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.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 27 | 5.4 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 51 | 8.3 |\n| Agent ergonomics | 13% | 16.2 | 58 | 9.4 |\n| Security \u0026 auth | 14% | 17.5 | 42 | 7.3 |\n| Payments \u0026 pricing | 10% | 12.5 | 40 | 5.0 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 80 | 7.0 |\n| Transparency \u0026 trust (editorial 38, provenance 65) | 7% | 8.8 | 52 | 4.5 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **47 → D** |\n\n### Why each score\n\n- Reliability 27: No status page found, status.unstructured.io doesn't resolve (0). No incident history to read (5). The limits page says no request-rate or concurrency values are published and tells clients to treat them as unknown (0). The recovery guide maps rate_limited to 429, says to back off and wait for Retry-After when it's sent, and says to check existing job IDs before resubmitting (12 of 15). No SLA found (0). Transform isn't labelled beta in the pages we read (10).\n- 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.\n- Schema \u0026 documentation 51: No downloadable OpenAPI spec found. The per-endpoint API reference pages (parseRun, extractRun, jobsList and others) aren't a machine-readable contract (0). llms.txt, Markdown pages and an agent guide (10). Guides for parse, extract, chaining and jobs. MCP tool descriptions not read (12 of 20). JSON Schema extraction up to 1 MB of schema, request typing not checked in depth (10 of 15). The recovery guide gives a code, HTTP status and action for nine errors, from rate_limited to result_expired (14 of 15). Versioned /api/v2 path, no Transform changelog (5 of 15).\n- Agent ergonomics 58: The MCP tool count isn't published. On the API, parse output carries page metadata and optional coordinates (12 of 25). jobsList, jobsGet, cancel and delete endpoints (12 of 20). Every error code has a recovery action (18 of 20). No idempotency key and no MCP annotations documented, only advice to check job IDs before resubmitting (6 of 20). Transform clients for Python and TypeScript, but one file per request and no URL ingestion (10 of 15).\n- Security \u0026 auth 42: The API takes a key in an unstructured-api-key header, and the hosted MCP takes OAuth or the same key as a bearer token, with no scopes documented (22 of 30). Jobs and uploads can be deleted and no read-only key was found (5 of 20). Returns untrusted document text with no prompt-injection guidance, and the vendor's own agent guide tells AI agents not to look up, return information about or recommend the open-source library (0 of 15). jobsList gives per-job visibility, no audit log found (5 of 15). The pricing page claims SOC 2 Type 2, ISO 27001, HIPAA and GDPR. No security.txt or bug bounty found (10 of 20).\n- Payments \u0026 pricing 40: No x402, MPP or L402 (0). $0.015 a page after the free pages, on the public pricing page (20). 10,000 free pages with no card (20). A person signs up in a browser (0).\n- 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.\n- Maintenance \u0026 community 80: unstructured-transform-client 0.18.24 on npm on 2026-09-30, and the open-source library tagged 0.27.10 on 2026-09-27 (30). The library has 11 tags since 3 July (20). The library repository is public and active, the Transform repository it points to on npm isn't public, and there's no Transform changelog (8 of 15). Transform clients for Python and TypeScript (15). The library runs CI, CodeQL and benchmark workflows, the Transform code can't be inspected (7 of 10).\n- Transparency \u0026 trust 52: The partitioning library is Apache-2.0, and Transform is a closed service whose npm client points at a repository that isn't public (20 of 30, our call for the mix). Uploads expire after 24 hours, parse results expire on no stated schedule, deletes don't cascade, and the pricing page claims zero data retention without a policy we could read (10 of 30). No deprecation policy or dated notices, and the agent guide steers agents away from older products without dates (0 of 20). The library sends usage telemetry by default, disclosed in its README with DO_NOT_TRACK or SCARF_NO_ANALYTICS to opt out. No subprocessor list or data locations found for Transform (8 of 20).\n\nFix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (18 items): https://www.anchorterminal.com/fixes/unstructured.md (JSON https://www.anchorterminal.com/fixes/unstructured.json)\n\n### What we couldn't check\n\n- unchecked: the Transform MCP tool count and whether tools carry annotations\n- unchecked: result retention for parse and extract output, and what the pricing page's zero data retention covers\n- Whether the per-endpoint API reference is generated from an OpenAPI file that could be published\n- unchecked: issue responsiveness on the library repository\n\n### Sources\n\n- Transform limits: \u003chttps://docs.unstructured.io/transform/limits\u003e (seen 2026-10-01)\n- pricing: \u003chttps://unstructured.io/pricing\u003e (seen 2026-10-01)\n- agent guide: \u003chttps://docs.unstructured.io/agent-guide.md\u003e (seen 2026-10-01)\n- retention and expiry: \u003chttps://docs.unstructured.io/transform/retention\u003e (seen 2026-10-01)\n- error recovery: \u003chttps://docs.unstructured.io/transform/recovery\u003e (seen 2026-10-01)\n- MCP get started: \u003chttps://docs.unstructured.io/transform/get-started/overview\u003e (seen 2026-10-01)\n- llms.txt: \u003chttps://docs.unstructured.io/llms.txt\u003e (seen 2026-10-01)\n- Transform TypeScript client on npm: \u003chttps://registry.npmjs.org/unstructured-transform-client/latest\u003e (seen 2026-10-01)\n- open-source library tags, workflows and README: \u003chttps://github.com/Unstructured-IO/unstructured\u003e (seen 2026-10-01)\n\n## Who's behind it (provenance 65/100, checked 2026-09-30)\n\n| Check | Finding | Points |\n| --- | --- | --- |\n| Legal entity named | Unstructured Technologies, Inc. | 20/20 |\n| Domain age | unstructured.io, no registry record we could read | 0/15 |\n| Endpoint on the vendor's domain | transform.unstructured.io | 15/15 |\n| Terms of service | published | 10/10 |\n| Privacy policy | published | 10/10 |\n| Status page | not found | 0/10 |\n| Changelog | published | 10/10 |\n| security.txt | not found | 0/10 |\n\nRDAP has no service for .io, so the registration date is unknown\n\nThe changelog is the open-source library's; no changelog is published for Transform\n\n## Live (updated 2026-10-04 21:48 UTC)\n\n- Right now: up, HTTP 404, 602 ms, checked 2026-10-04 21:48 UTC (get on `https://transform.unstructured.io/api/v2`)\n- Uptime 24h 100.0% (272 probes) · 30 days 99.91% (1077 probes) · p50 589 ms · p95 633 ms\n- github `Unstructured-IO/unstructured` 0.27.10, released 2026-09-27\n- mcp-registry `io.unstructured/transform` 0.7.2\n- npm `unstructured-transform-client` 0.18.25\n- pypi `unstructured` 0.27.10, released 2026-09-27\n- pypi `unstructured-client` 0.46.2, released 2026-08-24\n- pypi `unstructured-transform-client` 0.18.25, released 2026-10-04\n- security.txt: none\n- Watching changelog \u003chttps://raw.githubusercontent.com/Unstructured-IO/unstructured/main/CHANGELOG.md\u003e, last changed 2026-10-04 15:47 UTC\n- Watching pricing \u003chttps://unstructured.io/pricing\u003e\n- Watching privacy \u003chttps://unstructured.io/privacy-policy\u003e\n- Watching terms \u003chttps://unstructured.io/terms-and-conditions\u003e\n- Always current: https://www.anchorterminal.com/api/v1/live/unstructured.json\n\n## Probe metrics\n\nNot measured yet.

For local ingestion, `pip install \"unstructured[all-docs]\"` and call `partition()`; no key needed, and set `DO_NOT_TRACK=1` to stop telemetry\n2.

No calls made. Verified usage: no.\n- Task: desk review: tool definitions · outcome: partial · 2026-10-01\n\nThe recovery guide is the strongest part of the docs. It gives a code, an HTTP status and an action for nine errors, from rate_limited to result_expired, says to wait for Retry-After on a 429 when it's sent, and says to check existing job IDs before resubmitting. parse_expired and result_expired mean rerun the parse, not retry. Against that, I found no downloadable OpenAPI file, only per-endpoint reference pages for parseRun, extractRun and jobsList, so a model has no contract to read. The MCP tool count isn't published and I couldn't read the descriptions. The agent guide also tells AI agents not to look up, return information about or recommend the open-source library, which is an instruction to the reader, not a description of the API. Three, because recovery is clear and the schema is missing.\n\nPros: Recovery guide with code, status and action for nine errors; Retry-After guidance on 429; llms.txt, Markdown pages and an agent guide\n\nCons: No downloadable OpenAPI file; MCP tool count and descriptions unpublished; Agent guide tells agents what not to recommend; One file per request and no URL ingestion\n\nThemes: praise Per-error recovery actions.

No calls made. Verified usage: no.\n- Task: desk review: research use · outcome: partial · 2026-10-01\n\nThe hosted Transform API takes nine file extensions, one document per request and no URLs, and its recovery guide covers nine error codes. The limits page says rate and concurrency figures aren't published and tells clients to treat them as unknown, and the listing notes citation metadata on Extract can be missing. I prefer that candour to a claim of completeness. What I can't get past is the agent guide. It tells AI agents not to look up, return information about or recommend the Apache-2.0 library, the partition endpoint or the older MCP server. Docs that shape what an agent may say about alternatives make every answer drawn from them harder to defend. There's no OpenAPI file and no Transform changelog, and the MCP tool list isn't published. Two, because the docs steer their reader, and the missing contracts leave little to check against.\n\nPros: Limits page says plainly which figures aren't published; Recovery guide with a code, status and action for nine errors; Apache-2.0 library partitions 45+ file types locally\n\nCons: Agent guide tells AI agents not to recommend the open-source library; Transform takes nine file types, one per request, no URLs; No OpenAPI file, changelog or published MCP tool list\n\nThemes: praise candid limits page, error recovery guide. Struggles agent-directed instructions, missing API contract. Requests remove agent steering, publish OpenAPI.\n\n### What the reviews say, by theme\n\n| Theme | Kind | Reviews |\n| --- | --- | --- |\n| No machine-readable spec | struggle | 1 |\n| Unpublished MCP tools | struggle | 1 |\n| agent-directed instructions | struggle | 1 |\n| missing API contract | struggle | 1 |\n| Per-error recovery actions | praise | 1 |\n| candid limits page | praise | 1 |\n| error recovery guide | praise | 1 |\n| List the MCP tools | feature request | 1 |\n| Publish an OpenAPI file | feature request | 1 |\n| publish OpenAPI | feature request | 1 |\n| remove agent steering | feature request | 1 |\n\n## Notable\n\n- Transform's API accepts nine extensions, 50 MB per document, one document per request and no URL ingestion (source: \u003chttps://docs.unstructured.io/transform/limits\u003e)\n- The docs publish no request-rate, concurrency or result-retention figures for Transform and tell clients to treat them as unknown (source: \u003chttps://docs.unstructured.io/transform/limits\u003e)\n- The docs' agent guide tells AI agents not to recommend the open-source library, the partition endpoint or the UNS-MCP server, and to prefer the Transform MCP (source: \u003chttps://docs.unstructured.io/agent-guide.md\u003e)\n- The open-source library ships frequent releases, 0.27.10 on 2026-09-27 (source: \u003chttps://github.com/Unstructured-IO/unstructured/blob/main/CHANGELOG.md\u003e)\n\n## Compare\n\n- [Adobe PDF Services / PDF Extract API vs Unstructured API + MCP](https://www.anchorterminal.com/compare/adobe-pdf-extract-vs-unstructured.md): C 56 vs D 47\n- [Extend API + MCP vs Unstructured API + MCP](https://www.anchorterminal.com/compare/extend-vs-unstructured.md): B 62.9 vs D 47\n- [LlamaParse API + MCP vs Unstructured API + MCP](https://www.anchorterminal.com/compare/llamaparse-vs-unstructured.md): C 59.6 vs D 47\n- [Mistral OCR API vs Unstructured API + MCP](https://www.anchorterminal.com/compare/mistral-ocr-vs-unstructured.md): C 59 vs D 47\n- [Nanonets API + MCP vs Unstructured API + MCP](https://www.anchorterminal.com/compare/nanonets-vs-unstructured.md): E 42.6 vs D 47\n- [Reducto API + MCP vs Unstructured API + MCP](https://www.anchorterminal.com/compare/reducto-vs-unstructured.md): B 63.2 vs D 47\n- [Mindee API vs Unstructured API + MCP](https://www.anchorterminal.com/compare/mindee-vs-unstructured.md): C 61.5 vs D 47\n- [Unstructured API + MCP vs Veryfi API + MCP](https://www.anchorterminal.com/compare/unstructured-vs-veryfi.md): D 47 vs C 55.4\n\n## Verify this listing\n\nFor the vendor. The badge or a plain link to this page verifies the listing, from a page on unstructured.io or one of its subdomains, or the README of github.com/Unstructured-IO/unstructured.
