Why the edge:
- Maintenance & community, Youtrust +51: Adobe Acrobat Sign 10 (The newest dated entry in the API release notes is November 2025, more than 180 days before this check, and the developer guide was last updated on 17 December 2025 (0). No dated API entries fall in the last 90 days (0). Closed service with release notes, a developer forum link and support. The GitHub repository's last commit is still 14 May 2026 (a redirect script), with the release notes page's content last changed on 30 October 2025 (its "Last update" line; a 22 January 2026 commit only added a redirect script), re-read from a clone on 4 November; its nine open issues are per the 8 October check. We didn't test a support channel (5 of 15). Adobe's SDK page says its SDKs are obsolete, and a Postman workspace is the suggested replacement (3 of 15). The SDK code hasn't changed since August 2022 and the repository has no CI workflow (2 of 10). Product release notes on helpx.adobe.com answered 403 and went unread, so newer product changes may exist. The developer guide and release notes on developer.adobe.com are per the 8 October check, not re-read on 4 November. 0+0+5+3+2 = 10.); Youtrust 61 (Read as a closed service. The changelog's newest entries are dated 21 October 2026 (30). Ten entries between 13 and 21 October 2026 (20). A help centre, contact@youtrust.com in the OpenAPI contact block, a changelog RSS feed and a feedback form for the AI connector. No public issue tracker (8 of 15). No official SDK; the GitHub organisation holds no client library and the docs point to generators and Postman (0 of 15). The OpenAPI file is current with the October changes and the MCP setup page was updated on 7 September 2026 (3 of 10). 30 + 20 + 8 + 0 + 3 = 61.)
- Schema & documentation, Youtrust +36: Adobe Acrobat Sign 54 (Graded on the REST v6 API. The live reference is a Swagger UI on secure.na1.adobesign.com, whose robots.txt disallows crawlers, so we didn't read it. The only downloadable contract found is a set of Swagger 1.2 files from August 2018 with 92 operations, and Adobe calls the SDKs built from it obsolete (12 of 25). developer.adobe.com/llms.txt returns 404 (0). The developer guide and a best practices page of 17 December 2025 state required scopes, valid state transitions and good and bad call patterns for each main endpoint (12 of 20). The 2018 files mark 231 of 489 parameters required and hold 99 enums (9 of 15). The guide has request and response examples and named error codes, with per-endpoint error lists in the reference we didn't read (10 of 15). The API is versioned in the path, and the release notes are dated by month, most recently November 2025 (11 of 15). Per the 8 October check, not re-read on 4 November, since Adobe's hosts are paused for this run.); Youtrust 90 (A public OpenAPI 3.0.0 file with 178 operations on 114 paths, a bearer scheme and 282 enums (25). developers.youtrust.com serves llms.txt, a per-section llms.txt and a Markdown twin of every page (10). Every operation has a description, 28 of them under 40 characters, and the guides explain the signature request lifecycle, when to use templates and the Tolerant Reader rule (14 of 20). Required fields, 282 enums, a Safe String type with stated rules, and a free-form metadata object (13 of 15). 1,307 examples in the file, every operation documents 400, 401, 403, 404, 405, 429 and 500, the error page gives the type, detail and invalid_params shape with retry guidance per code, and a list of error types is published (15). v3 in the path, a versioning page with compatibility rules, a Deprecated tag in the file, and a changelog with ten entries dated 13 to 21 October 2026 and an RSS feed, with no removal timeline (13 of 15). 25 + 10 + 14 + 13 + 15 + 13 = 90.)
- Reliability, Youtrust +24: Adobe Acrobat Sign 61 (Graded as a hosted API. status.adobe.com is Adobe's status page and the Unified SLA names it for outage notices, but the page is drawn by script and no Acrobat Sign component or component history was confirmed, so the line is scored as adobe-pdf-extract's is (15 of 20). No incident history could be read, so the last 90 days are scored as unreadable (5). Numbers are published for `/search` (1,000 a minute, 2,500 an hour, 7,200 a day) and for identical GET calls (three a minute on Global, Enterprise and Developer tiers). Per-endpoint limits depend on the plan and aren't published (9 of 15). 429 responses carry `Retry-After` and a `retryAfter` field, the guide asks for exponential backoff, and `If-Match` ETags stop stale updates. No idempotency key was found for `POST /agreements` (12 of 15). The Unified SLA of 3 August 2026 commits to 99.9 per cent for Acrobat Sign Solutions for Enterprise, with credits of 5 to 25 per cent (10). REST v6 is generally available (10). Per the 8 October check, not re-read on 4 November, since Adobe's hosts are paused for this run. 15+5+9+12+10+10 = 61.); Youtrust 85 (Read with the hosted lines and scored on the Public API v3 at api.yousign.app, the surface both MCP servers call. yousign.statuspage.io on Atlassian Statuspage has an incident history and a feed (20). Between 5 August and 3 November 2026 the feed records HTTP 500 errors on the public API from 11:24 to 11:35 and 14:42 to 15:19 CEST on 7 October, caused by an infrastructure provider; about 45 minutes of delayed advanced and unavailable qualified signatures on 13 August; identity verification delays at a third-party provider on 1 September (most of a day), 2 September, 14 September and 16 October (33 minutes); 16 minutes of delayed seals on 16 October; email delays to Microsoft mailboxes on 4 September; and Orange network routing on 2 October. Several incidents, mostly at identity providers, and no outage of the core API over an hour (20). Rate limits are published per minute and hour for each environment (15). 429 answers Too many requests with x-ratelimit headers and a Ratelimit-Reset in seconds, the docs say to slow down and increase the delay, and there are no idempotency keys and no Retry-After (10 of 15). The API pricing page states 99 per cent and 99.9 per cent SLAs on the Plus and Pro plans (10). v3 is generally available (10). 20 + 20 + 15 + 10 + 10 + 10 = 85.)
- Payments & pricing, Youtrust +15: Adobe Acrobat Sign 25 (Read with the hosted rubric. No x402, MPP or L402 found (0). Acrobat team plan prices are public, but the pricing page doesn't say they include API access, and Acrobat Sign Solutions is by quote with no per-transaction price. We scored between plan-only and contact sales (5). The Developer Edition is free with API access. The sign-up page says no commitments and doesn't mention a card, and we didn't run the form (20). A person must create an Adobe ID, register an application and approve OAuth in a browser (0). Per the 8 October check, not re-read on 4 November, since Adobe's hosts are paused for this run.); Youtrust 40 (Read with the hosted rubric. No x402, MPP or L402 (0). API plan prices are public without login, Plus from €104 a month and Pro from €129 with €2 per extra signature (20). The sandbox trial lasts 40 days and needs no credit card per the API pricing page (20). A person signs up in a browser and an Admin creates the key there (0). 0 + 20 + 20 + 0 = 40.)
- Agent ergonomics, Youtrust +8: Adobe Acrobat Sign 55 (List calls take `pageSize` and return ETags for 304 responses. No field selection was found (13 of 25). Cursor pagination with `page.nextCursor`, a `/search` endpoint and a 500-agreement page cap (15 of 20). Errors are JSON with a stable code and message, such as `INVALID_API_ACCESS_POINT`, `THROTTLING_TOO_MANY_REQUESTS` and `RESOURCE_MODIFIED` (15 of 20). No idempotency key. `If-Match` protects updates and a `DRAFT` state lets a caller build an agreement before sending (8 of 20). A caller must first discover the account's shard, sending a file takes an upload call and then an agreement call, and Adobe marks every SDK deprecated (4 of 15). Per the 8 October check, not re-read on 4 November, since Adobe's hosts are paused for this run.); Youtrust 63 (List calls take limit and filters, and a signature request's documents, signers and fields are fetched by their own calls, so responses stay moderate. No field selection (14 of 25). Cursor pagination with limit and after on 26 list operations, with status, workspace_id, created_at and date range filters (20). Errors carry a type an agent can branch on, a detail and invalid_params naming the field and reason, with guidance to retry only 500 and 503 (17 of 20). No idempotency keys. A request is a draft until activate, pause and cancel are explicit calls, and the MCP tools' annotations couldn't be read (6 of 20). A first send takes four calls (create, add document, add signer with fields, activate), identity and seal options add more, and there is no official SDK in any language (6 of 15). 14 + 20 + 17 + 6 + 6 = 63.)
