## Which one, for what

### Datalab (B)

Good for: Hosted PDF and Office conversion and schema extraction with citations, from the team behind Marker.

Ahead on:
- Reliability, 58 against 45
- Schema & documentation, 89 against 61
- Agent ergonomics, 73 against 47
- Security & auth, 56 against 30
- Payments & pricing, 40 against 35
- Maintenance & community, 79 against 8

Watch for: API keys carry no scopes; spend caps per key are the only limit

### Nanonets API + MCP (E)

Good for: A team that wants schema-shaped JSON from mixed documents and is happy to sort out the two API generations.

Watch for: No public changelog and no dated release in the last 90 days


## Why the edge

### Maintenance & community: Datalab +71

- Datalab (79): Closed hosted service. Python SDK 0.9.1 on 6 November 2026 and a changelog entry on 4 November (30). Over twenty dated changelog entries since 8 August (20). Support by email, a Discord and public GitHub repositories for the open-source models; replies not sampled (12 of 15). An official Python SDK, current, no other languages (12 of 15). Package health not checked beyond release dates (5 of 10). 30+20+12+12+5 = 79.
- Nanonets API + MCP (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).

### Schema & documentation: Datalab +28

- Datalab (89): An OpenAPI 3.1 operation embedded in each reference page (spec version 0.0.1), no single downloadable file found (22 of 25). llms.txt with 159 pages and Markdown twins (10). Recipes say when to use each processor and mode (15 of 20). Typed request schemas with enums for output format and mode (12 of 15). An error table with type, HTTP code and whether to retry, plus SDK exception mapping (15). A written version policy and a dated changelog (15). 22+10+15+12+15+15 = 89.
- Nanonets API + MCP (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: Datalab +26

- Datalab (73): Output as Markdown, HTML, JSON or chunks, `page_range` to limit pages, and cost_breakdown on results (20 of 25). File listing and pipeline endpoints, little else to paginate (14 of 20). Typed errors with retry guidance an agent can follow (18 of 20). No idempotency key; the docs say to poll a known request ID instead of resubmitting, and webhooks may be retried (12 of 20). Official Python SDK and CLI, one language (9 of 15). 20+14+18+12+9 = 73.
- Nanonets API + MCP (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: Datalab +26

- Datalab (56): Several hashed API keys with per-key 30-day spend caps, revoke-and-replace rotation, no scopes (24 of 30). Spend caps limit damage; results and files can be deleted by the key holder, and there's no read-only key (10 of 20). Returns document text with no prompt-injection guidance (2 of 15). cost_breakdown per request and usage tracking in the dashboard (8 of 15). A Secureframe trust centre and a SOC 2 report on the Team plan, TOTP enforcement for teams; no disclosure policy or security.txt found (12 of 20). 24+10+2+8+12 = 56.
- Nanonets API + MCP (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).

### Reliability: Datalab +13

- Datalab (58): Hosted lines. Status page at status.datalab.to (incident.io) with Website and Datalab API components; the history page is drawn by script, so components are confirmed and history isn't (15 of 20, 5 for history). Rate limits per plan with numbers, plus page and size limits (15). 429 is retryable with sample backoff, and 500 and 529 say to check a known request ID before resubmitting; webhooks deduplicate by request_id (13 of 15). Custom SLAs only for Enterprise (0). Generally available (10). 15+5+15+13+0+10 = 58.
- Nanonets API + MCP (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).

### Payments & pricing: Datalab +5

- Datalab (40): No x402, MPP or L402 (0). Per-1,000-page rates for every processor and add-on on the public pricing page (20). A $10 to $20 monthly allowance with no card (20). A person signs up in a browser (0). 0+20+20+0 = 40.
- Nanonets API + MCP (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).

## Verdicts

**Datalab.** Datalab's hosted API from the Marker and Surya team converts and extracts documents with published per-1,000-page rates, a monthly free allowance with no card, typed retryable error codes, a written version policy and an active dated changelog. API keys have spend caps but no scopes, and no prompt-injection guidance or disclosure policy was found.

**Nanonets API + MCP.** Extraction API returns Markdown, CSV or JSON, with named fields or a JSON schema. No public changelog and no dated release in the last 90 days.

## Before you call either

### Datalab

1. Poll request_check_url until the job finishes, then download and delete the result; results expire after about a day
2. Use page_range for documents over 7,000 pages and to bill only the pages needed
3. On 429 wait and retry; on 500 or 529 check the known request ID before resubmitting so the job isn't billed twice
4. Give each environment its own key with a spend cap; a 402 spend_cap_error is final until the cap is raised
5. Treat converted text as untrusted input, never as instructions

### Nanonets API + MCP

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
