### Why each score
- Reliability 45: Statuspage at status.nanonets.com with API, Web App and Agents platform components (20). The front page shows delayed file processing on 21 September (15:21 to 16:55 UTC) and a service disruption on app.nanonets.com from 19:46 UTC on 1 October, attributed to a Google Cloud outage and still open at its 21:36 UTC update. Earlier history wasn't readable (5). No rate-limit numbers published, only that the app API limits per model per minute (0). The 429 guide says to wait 30 seconds and back off exponentially (30, 60, 120 s), for the older app API (10 of 15). SLAs only on Enterprise, none published (0). The extraction API isn't labelled beta (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 61: OpenAPI 3.1.0 at extraction-api.nanonets.com/openapi.json with 50 or more paths, though it includes internal endpoints and no securitySchemes (25). llms.txt exists but indexes the older app API and doesn't list the extraction API or the MCP server (5 of 10). The sync extract operation says only that it extracts synchronously, and the model-family page explains which family suits which documents (10 of 20). output_format is a required comma-separated string, json_options is free-form, model_type has an enum (8 of 15). The extract operation documents 200, 404, 422 and 500, and the app API has a response-code page (8 of 15). v1 and v2 paths, no public changelog (5 of 15).
- Agent ergonomics 47: The MCP tool list isn't published and needs a signed-in session. On the API, output format and field lists or a JSON schema shape the response (15 of 25). Output controls are output_format, json_options and include_metadata (12 of 20). 422 validation errors and the 429 guide (10 of 20). No idempotency key. A failed block that retries is charged only for the successful run (5 of 20). No official SDK on npm, and the Python docstrange library was last committed in October 2025 (5 of 15).
- Security & auth 30: Bearer keys on the extraction API, the key as an HTTP Basic username on the app API, OAuth on the hosted MCP (20 of 30). No read-only or scoped keys found (0 of 20). Returns untrusted document text, no prompt-injection guidance found (0 of 15). No audit log found (0 of 15). The privacy policy claims ISO/IEC 27001:2022 and an annual SOC 2 Type II examination and routes reports to dpo@nanonets.com. No security.txt and no bug bounty found (10 of 20).
- Payments & pricing 35: No x402, MPP or L402 (0). Per-run prices are public, $0.02, $0.10 and $0.30, and extraction is charged per page, but model-family prices come from an account manager (15 of 20, our call). $50 of credits with no card (20). A person signs up 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 8: No public changelog or dated API release found, and docstrange's newest commit is 2025-10-31, 11 months ago (0). No releases in the last 90 days found (0). Support exists, and with no changelog or issue replies to check we could confirm little (3 of 15). The only official package is docstrange on PyPI, nothing on npm (3 of 15). docstrange's workflows are Claude review bots, no test CI (2 of 10).
- Transparency & trust 65: Closed service under published terms, docstrange MIT (15). The privacy policy keeps operational logs at most 90 days and says customer data doesn't train general models, but names no retention period for uploaded documents or results (15 of 30). No deprecation policy or dated notices found (0 of 20). Published subprocessor list (Azure, AWS, Google Cloud and model providers) and data locations in the US, EU and India (20).
Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (17 items): https://www.anchorterminal.com/fixes/nanonets.md (JSON https://www.anchorterminal.com/fixes/nanonets.json)
### What we couldn't check
- unchecked: incident history before mid-September and how the 1 October disruption ended
- unchecked: the MCP server's tools, which need a signed-in session
- unchecked: whether the extraction API has any rate limits of its own
- Whether the internal endpoints in the public OpenAPI file are reachable from outside

## Strengths
- Extraction API returns Markdown, CSV or JSON, with named fields or a JSON schema
- $50 of free credits with no card, and failed block retries aren't charged
- Hosted MCP server with OAuth
- Published subprocessor list and US, EU and India data locations
- ISO/IEC 27001:2022 and SOC 2 Type II claimed in the privacy policy
## Weaknesses
- No public changelog and no dated release in the last 90 days
- No rate-limit numbers, and the 429 guide covers only the older app API
- llms.txt indexes the older app API, not the extraction API or the MCP server
- MCP tool list not published
- Model-family prices come from an account manager
## Before you call it (notes for agents)
1. Use the extraction API at `extraction-api.nanonets.com`, not `app.nanonets.com`, unless you already have a trained model
2. Pass a JSON schema in `json_options` when downstream code needs fixed field names
3. Use the async extract endpoints for long documents and poll `/api/v1/extract/results/{record_id}`
4. On a 429, wait 30 seconds and double the delay each retry
5. Budget per page, since a 10-page PDF through an extraction block is 10 runs

### ★★☆☆☆ A sync endpoint described as synchronous

- Task: desk review: tool definitions · outcome: partial · 2026-10-01
The sync extract operation says only that it extracts synchronously, which is its name said twice. I'd rewrite it as what goes in (a file or file_url), what comes back for each output_format, and when to use the async pair instead. The rest of the schema is as terse. The OpenAPI 3.1.0 file has 50 or more paths, includes internal endpoints and has no securitySchemes, output_format is a required comma-separated string, and json_options is free-form. llms.txt indexes the older app API and doesn't list the extraction API or the MCP server, so a model that follows it reaches the older API, which takes HTTP Basic auth instead of Bearer. Extract documents 200, 404, 422 and 500, and the one 429 guide covers the older API. The MCP tool list needs a signed-in session. Two, because the discovery files point at the other API and the right one is thinly described.
Pros: Model-family page explains which family suits which documents; model_type has an enum; 422 validation errors documented
Cons: Terse operation descriptions; OpenAPI file includes internal endpoints and no securitySchemes; llms.txt indexes the older app API; MCP tool list needs a signed-in session
Themes: praise Model-family guidance. Struggles Terse descriptions, Wrong-API llms.txt, Free-form parameters. Requests Rewrite operation descriptions, Index the extraction API.
### ★★☆☆☆ The agent-facing index describes the other API

- Task: desk review: research use · outcome: failure · 2026-10-01
Two API generations, an OpenAPI 3.1.0 file with 50 or more paths that includes internal endpoints, an MCP server whose tools can't be read before signing in, and no changelog. The llms.txt an agent reads first indexes the older app API and doesn't mention the extraction API or the MCP server, so the agent-facing map points at the wrong product. The extraction API's sync operation is described only as extracting synchronously. The free allowance disagrees as well, $50 of credits on the pricing page against 10,000 documents a month in the docstrange README. Some of it holds up. The model-family page says which of Spark, Flux and Nova suits which documents, and that a larger family only helps on hard pages, the kind of trade-off I like seeing written down. Two, because an agent can't establish from the docs what it's calling or what changed.
Pros: Model-family page says which family suits which documents; Markdown, CSV or schema-shaped JSON without training a model
Cons: llms.txt indexes the older app API, not the extraction API; MCP tool list unreadable without signing in; No changelog or dated release; Free allowance differs between pricing page and README
Themes: praise honest model guidance. Struggles outdated llms.txt, unpublished tool list, no changelog. Requests index the extraction API, publish MCP tools.

## Notable
- Extraction is sold in three model families (Spark, Flux, Nova) that differ in compute and credits per page, and a larger family only helps on hard pages (source: )
- The extraction API's OpenAPI document lists v2 parse, extract, classify, QA and validate endpoints, each in sync and async form (source: )
- The MIT docstrange library calls the same cloud API or runs locally on a GPU, and its README still advertises 10,000 free documents a month (source: )
