# Google Cloud Document AI > Google Cloud's service for OCR, layout parsing, chunking, form and table extraction, classification and splitting of documents. Work runs through processors created per project and location. Access is a REST and gRPC API with client libraries in eight languages. - Canonical: https://www.anchorterminal.com/tools/google-cloud-document-ai - Markdown: https://www.anchorterminal.com/tools/google-cloud-document-ai.md (~9,600 tokens) - Slim: https://www.anchorterminal.com/tools/google-cloud-document-ai.min.md (~2,080 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/google-cloud-document-ai.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-09 ## Overview **Grade BB · 73.9/100 · rank #82 of 950 · #1 in Document parsing & extraction · agent-ready · confidence medium** More from Google Cloud, listed separately because each is its own product: [Gemini Developer API](https://www.anchorterminal.com/tools/gemini-api.md) (Model APIs & inference), [Gemini Embedding](https://www.anchorterminal.com/tools/gemini-embedding.md) (Embeddings & rerankers), [Vertex AI Gemini tuning](https://www.anchorterminal.com/tools/vertex-ai-tuning.md) (Fine-tuning), [Google Cloud Model Armor](https://www.anchorterminal.com/tools/google-model-armor.md) (Guardrails & safety filters), [Google Imagen](https://www.anchorterminal.com/tools/google-imagen.md) (Image generation), [Google Veo](https://www.anchorterminal.com/tools/google-veo.md) (Video generation), [Google Lyria](https://www.anchorterminal.com/tools/google-lyria.md) (Music generation), [Google Cloud Speech-to-Text](https://www.anchorterminal.com/tools/google-speech-to-text.md) (Speech-to-text), [Gemini Live API](https://www.anchorterminal.com/tools/gemini-live.md) (Conversational voice agents), [Agent Development Kit (ADK)](https://www.anchorterminal.com/tools/google-adk.md) (Agent frameworks & SDKs), [Google Cloud Secret Manager](https://www.anchorterminal.com/tools/google-secret-manager.md) (Secrets & credential vaults), [Google Weather API (Maps Platform)](https://www.anchorterminal.com/tools/google-weather-api.md) (Weather & climate data), [Chrome DevTools MCP](https://www.anchorterminal.com/tools/chrome-devtools-mcp.md) (Browser automation), [Google Maps Platform + Grounding Lite MCP](https://www.anchorterminal.com/tools/google-maps-platform.md) (Maps, geocoding & places), [Google Cloud Translation](https://www.anchorterminal.com/tools/google-cloud-translation.md) (Translation), [Google Calendar API](https://www.anchorterminal.com/tools/google-calendar-api.md) (Calendars & scheduling), [Firebase Cloud Messaging](https://www.anchorterminal.com/tools/firebase-cloud-messaging.md) (Notifications), [Google Drive API + MCP](https://www.anchorterminal.com/tools/google-drive-api.md) (File storage & sharing), [Gemini CLI](https://www.anchorterminal.com/tools/gemini-cli.md) (Agent harnesses), [Google Search Console API](https://www.anchorterminal.com/tools/google-search-console.md) (SEO & search visibility), [Google Ads API](https://www.anchorterminal.com/tools/google-ads-api.md) (Advertising & campaign operations), [Google Forms API](https://www.anchorterminal.com/tools/google-forms.md) (Forms, surveys & structured intake), [Google Sheets API](https://www.anchorterminal.com/tools/google-sheets-api.md) (Spreadsheets & operational tables), [Gmail API](https://www.anchorterminal.com/tools/gmail-api.md) (Mailbox access). ## Assessment A public Discovery document with 42 methods, IAM roles that can limit a caller to processing, a `fieldMask` that trims responses, and a 99.9 per cent SLA on the US and EU endpoints. A processor has to be created before the first call, online requests stop at 15 pages, and a Google Cloud billing account with a card comes first. ## Facts | Field | Value | | --- | --- | | Vendor | Google Cloud (https://cloud.google.com/document-ai) | | Kind | HTTP API | | Category | Document parsing & extraction (https://www.anchorterminal.com/categories/document-extraction) | | Transport | HTTP | | Auth | OAuth · Access starts with a Google Cloud project that has the Document AI API and billing enabled, all self-serve in the console. Calls take an OAuth 2.0 bearer token from a service account or Application Default Credentials in the `Authorization` header, with the single scope `https://www.googleapis.com/auth/cloud-platform`. IAM decides what the caller can do, through four predefined roles from `roles/documentai.apiUser` (process only) to `roles/documentai.admin`, grantable on a project or one processor. The docs show no API key flow. Three pretrained processors are open to limited access customers only, by request form. | | Pricing | Freemium ($1.50 / 1k pages) · Pay as you go per page, with no plan. Enterprise Document OCR is $1.50 per 1,000 pages ($0.60 past 5 million), and the pricing page shows the first 1,000 at $0.00. Layout Parser is $10, Form Parser and Custom Extractor $30 ($20 past a million), Custom Classifier and Splitter $5 ($3 past a million), all per 1,000 pages. Invoice, expense and identity parsers are $0.10 per document of up to 10 pages. A deployed custom processor version costs $0.05 an hour to host. Failed requests are not billed. New customers get $300 of credit for 90 days, and sign-up needs a credit card or other payment method (https://cloud.google.com/document-ai/pricing, https://docs.cloud.google.com/free/docs/free-cloud-features). | | x402 | No · No x402, MPP or L402 in the docs, the Discovery document or the pricing page (checked 2026-10-09). | | Licence | Proprietary service under the Google Cloud Platform Terms of Service.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 90 | 18.0 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 81 | 13.2 | | Agent ergonomics | 13% | 16.2 | 70 | 11.4 | | Security & auth | 14% | 17.5 | 80 | 14.0 | | Payments & pricing | 10% | 12.5 | 20 | 2.5 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 80 | 7.0 | | Transparency & trust (editorial 80, provenance 99) | 7% | 8.8 | 90 | 7.9 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **73.9 → BB** | ### Why each score - Reliability 90: Hosted reading. Google Cloud status page with a JSON incident feed (20). The feed lists five incidents since 11 July 2026 and none names Document AI, among them the 20 August outage that lists 27 products. The page shows only broad incidents (30). Quotas published with numbers, 1,800 requests a minute per user, 120 online process requests a minute per processor type in `us` and `eu` and 5 concurrent batch requests (15). No retry or backoff guidance was found on the quotas, limits or request pages. Processing changes no state and failed requests are not billed, so a retry is safe (5 of 15). 99.9 per cent monthly SLA for online and batch prediction on a multi-region endpoint, with none for the best effort tier (10). v1 is GA (10). - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 81: A public Discovery document for v1, revision 20260929, with 42 methods and 326 schemas, and a second for v1beta3 (25). docs.cloud.google.com/llms.txt answers 404 and `Accept: text/markdown` returns HTML. A page address with `.md.txt` added answers as Markdown, which no page we read links, so half (5 of 10). Method descriptions are one line each. The overview has a table of which processor fits which job (15 of 20). 952 of 966 properties carry a description and 58 are enums. Required fields are marked only in prose, the three document sources are a union stated in a comment, and `advancedOcrOptions` is a free list of strings (11 of 15). The request page has samples in curl, PowerShell, C#, Go, Java, Node.js, Python and Ruby. No Document AI page listing error codes was found (10 of 15). v1 and v1beta3, and dated release notes with a feed (15). - Agent ergonomics 70: API reading. `fieldMask` picks top-level and page fields of the response, `imagelessMode` removes page images, and page selectors limit what is read. Without a mask the Document carries every token with geometry (20 of 25). List calls page with `pageSize` and `pageToken`, operations take a filter, and Layout Parser takes a chunk size. An online request stops at 15 pages, or 30 with `imagelessMode`, and longer files go through a batch job and Cloud Storage (15 of 20). Errors follow Google's status and message model, with no Document AI error page found (12 of 20). No idempotency key. Failed requests are not billed and processing changes no state, while a repeated successful call bills again. Batch operations can be polled (12 of 20). A processor has to be created before the first call and the host depends on its location. Client libraries in eight languages (11 of 15). - Security & auth 80: OAuth 2.0 bearer tokens from service accounts with IAM. The docs and samples send the token only in the `Authorization` header (30). `roles/documentai.apiUser` allows processing only, roles can be granted on one processor, and deny policies and VPC Service Controls are supported. Nothing asks for confirmation before a processor is deleted (17 of 20). The service returns text from untrusted documents and no guidance on injected instructions was found in the pages read (0 of 15). The audit logging page lists each method by permission type. `ProcessDocument` writes Data Access logs, which Google Cloud leaves off until the owner enables them (13 of 15). google.com security.txt valid to 1 April 2030 with the reward programme. The Document AI security page states ISO 27001, SOC 2 and SOC 3 audits, FedRAMP High and HIPAA (20). - Payments & pricing 20: No x402, MPP or L402 (0). Per-page prices for every processor published without a login (20). The first 1,000 OCR pages show at $0.00 and new customers get $300 of credit, but the Free Trial page says sign-up needs a credit card or other payment method (0). A person creates the project and billing account in a browser (0). - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 80: Read as a closed service with official SDKs. The newest release note is 21 September 2026 and the Node.js client 10.2.0 shipped on 8 October 2026 (30). Release notes on 17 July and 21 September, Node.js releases on 4 August, 8 September, 28 September and 8 October, and Python 3.16.0 on 1 October, all in the last 90 days (20). Release notes with a feed, Google Cloud support and public issue trackers for each client library. We did not read the trackers (10 of 15). Official client libraries in eight languages, with Python and Node.js current (15). Python declares 3.10 to 3.15 and Node.js 22 or later. CI results were not checked (5 of 10). - Transparency & trust 90: Closed service under the Google Cloud terms, with Apache-2.0 client libraries (15 of 30). The security page says online requests are processed in memory, batch documents are deleted after processing with a failsafe of one day, and content is never used to train Document AI models. The service terms' training restriction and the Data Processing Addendum agree. Layout Parser versions on Gemini 3.0 route globally, which the docs state (27 of 30). The lifecycle page promises six months' notice for stable versions and lists a deprecation date per version, and the Cloud terms promise 12 months before a backwards-incompatible API change. The legacy processor notice of 17 February 2026 gave until 30 June 2026, about four and a half months (18 of 20). `us` and `eu` multi-regions, seven single regions and a public sub-processor list (20). Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (18 items): https://www.anchorterminal.com/fixes/google-cloud-document-ai.md (JSON https://www.anchorterminal.com/fixes/google-cloud-document-ai.json) ### What we couldn't check - unchecked: the status feed held seven incidents back to February 2026. Whether smaller Document AI incidents are shown anywhere else was not established. - unchecked: the pricing page shows the first 1,000 Enterprise Document OCR pages at $0.00 and does not say on the page whether that allowance is monthly. - unchecked: how quota errors are returned (HTTP status and body) and whether the client libraries retry them. No Document AI page read says. - unchecked: the GitHub issue trackers and CI results for the client libraries were not read. - unchecked: Google Cloud security bulletins were not searched for Document AI. - The Markdown twin address (`.md.txt` added to a docs page address) was tried from knowledge of Google's docs platform and is not linked from the pages read. One page was fetched that way. Schema counts it as half. - The Discovery document lists `access_token` and `key` as query parameters common to Google APIs. No deduction was taken, following the Speech-to-Text and Model Armor dossiers. The Gmail and Sheets dossiers took 10 on the same evidence. - `provenance.privacy` points at the Google Cloud Privacy Notice, not policies.google.com/privacy as the older Google Cloud listings do. - `lastRelease` is the Node.js client 10.2.0 of 8 October 2026. The service's newest release note is 21 September 2026. - The lead's facts held. Its `interface` did not mention gRPC, which the docs also give. ### Sources - docs overview: (seen 2026-10-09) - release notes: (seen 2026-10-09) - Discovery document v1: (seen 2026-10-09) - REST reference: (seen 2026-10-09) - process method reference: (seen 2026-10-09) - pricing: (seen 2026-10-09) - quotas: (seen 2026-10-09) - limits: (seen 2026-10-09) - SLA: (seen 2026-10-09) - security and compliance: (seen 2026-10-09) - audit logging: (seen 2026-10-09) - IAM roles: (seen 2026-10-09) - setup and authentication: (seen 2026-10-09) - sending a processing request: (seen 2026-10-09) - Layout Parser: (seen 2026-10-09) - processor version lifecycle: (seen 2026-10-09) - regions: (seen 2026-10-09) - client libraries: (seen 2026-10-09) - file types (Markdown twin): (seen 2026-10-09) - status incident feed: (seen 2026-10-09) - Google Cloud Platform Terms of Service: (seen 2026-10-09) - Service Specific Terms: (seen 2026-10-09) - Google Cloud Privacy Notice: (seen 2026-10-09) - Cloud Data Processing Addendum: (seen 2026-10-09) - sub-processor list: (seen 2026-10-09) - Free Trial terms: (seen 2026-10-09) - security.txt: (seen 2026-10-09) - Python client changelog: (seen 2026-10-09) - Node.js client changelog: (seen 2026-10-09) - npm weekly downloads: (seen 2026-10-09) - PyPI weekly downloads: (seen 2026-10-09) ## Who's behind it (provenance 99/100, checked 2026-10-09) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | Google LLC | 20/20 | | Domain age | google.com, registered 1997-09-15 (29 years) | 15/15 | | Endpoint on the vendor's domain | google.com | 15/15 | | Terms of service | read, states 7 of the 7 things a reader expects | 10/10 | | Privacy policy | read, states 7 of the 8 things a reader expects | 9.3/10 | | Status page | status.cloud.google.com | 10/10 | | Changelog | published | 10/10 | | security.txt | valid | 10/10 | The endpoints are on googleapis.com, Google's API domain.

Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | Enterprise Document OCR | $1.50 | per 1,000 pages | Up to 5 million pages. $0.60 after. The page shows the first 1,000 at $0.00 | | OCR add-ons | $6 | per 1,000 pages | On top of the OCR price, Enterprise Document OCR v2 only | | Layout Parser | $10 | per 1,000 pages | Includes the first chunking. DOCX and HTML count 3,000 characters as a page | | Form Parser | $30 | per 1,000 pages | First million pages. $20 after | | Custom Extractor | $30 | per 1,000 pages | First million pages. $20 after. Hosting is $0.05 an hour per deployed version | | Custom Classifier or Splitter | $5 | per 1,000 pages | First million pages. $3 after | | Invoice, expense or identity parser | $0.10 | per transaction | Per document of up to 10 pages. Each further 10 pages is another $0.10 | | Bank statement parser | $0.75 | per transaction | Per classified document | Across all listings: https://www.anchorterminal.com/prices/index.md ## Strengths - Discovery document for v1 (revision 20260929) with 42 methods and 326 schemas, and descriptions on 952 of 966 properties - `fieldMask`, `imagelessMode` and page selectors on the process request limit what comes back and what is billed - The Document AI API User role allows processing only, roles can be granted on one processor, and process calls write Data Access audit logs once enabled - The security page says online requests are processed in memory and not written to disk, and content is never used to train Document AI models - 99.9 per cent monthly uptime SLA for online and batch prediction on the `us` and `eu` multi-region endpoints - Layout Parser returns layout-aware chunks with ancestor headings at $10 per 1,000 pages, and reads PDF, HTML, DOCX, PPTX and XLSX ## Weaknesses - An online request reads at most 15 pages (30 with `imagelessMode`). Longer files need a batch job through Cloud Storage - A processor must be created in a project and location before any document can be sent, and the endpoint host changes with the location - No guidance on retrying quota errors was found on the quotas, limits or request pages, and there is no idempotency key - The $300 trial credit and the free first 1,000 OCR pages both sit on a billing account that needs a card or other payment method - Legacy processor versions were discontinued on 30 June 2026 on a notice dated 17 February 2026, under the six months the version lifecycle page states - No guidance on instructions hidden in document text was found in the pages read - Layout Parser versions built on Gemini 3.0 use a global endpoint and, per the docs, do not meet data residency ## Before you call it (notes for agents) 1. Create a processor first (`processors.create` or the console), then POST to `https://LOCATION-documentai.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/processors/PROCESSOR_ID:process` 2. Use the host that matches the processor's location, `us-documentai.googleapis.com` or `eu-documentai.googleapis.com` 3. Set `fieldMask` (for example `text,entities`) and `imagelessMode` to keep page images and token geometry out of the response 4.

The badge or a plain link to this page verifies the listing, from a page on google.com or one of its subdomains, or the README of github.com/googleapis/google-cloud-python. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "google-cloud-document-ai", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
