Why the edge:
- Agent ergonomics, ConvertAPI +27: ConvertAPI 79 (Four MCP tools that list, search and describe converters before one convert tool (25). `StoreFile=true` returns a URL and FileId instead of base64, and converters can be filtered by tag or search; nothing to paginate (14 of 20). Numbered codes such as 4014 balance exhausted and 5003 password protected an agent can act on (17 of 20). No idempotency key; a repeated conversion is billed again, and MCP tool annotations weren't found (8 of 20). SDKs in nine languages and a CLI, with one required file parameter on most converters (15). 25+14+17+8+15 = 79.); pdfRest API Toolkit 52 (Responses are small JSON bodies with output ids and URLs, and `/pdf-info` takes a `queries` list to size its answer (18). Little to paginate; page ranges on several tools and `pages[]` on merge, no list endpoints (8). Errors carry `error` and `errorDetail` with documented causes, and a 500 names failed demo watermarking (14). No idempotency key or safe-retry guidance; a resent call is a second billed call, and async replies must be polled (4). Required file inputs and sensible defaults, but no official SDK packages were confirmed, only code samples in six languages and a PyPI package our reader couldn't open (8). 18 + 8 + 14 + 4 + 8 = 52.)
- Security & auth, ConvertAPI +18: ConvertAPI 55 (Tokens per environment with usage limits, JWTs with expiry and IP restriction, a separate Master Token for admin endpoints, OAuth on the hosted MCP (30), less 10 for the documented `Token` query parameter and its `Secret` and `Auth` aliases (20 of 30). Usage limits per token, but no read-only token, and stored files can be deleted (8 of 20). Extracted text and OCR output come from the documents, with no prompt-injection guidance (3 of 15). Usage statistics and per-environment consumption through the Master Token (10 of 15). ISO 27001 certificate linked, SOC 2 Type 2 stated with the report on request, cyber insurance; no disclosure policy, security.txt or bug bounty found (14 of 20). 20+8+3+10+14 = 55.); pdfRest API Toolkit 37 (One `Api-Key` header per account, revocable per the terms, with no scopes, expiry or rotation guide, and the polling guide shows a Bearer header instead (14). No read-only key; `/delete` removes uploaded files and there is no confirmation step, though demo output is watermarked (4). Extracted text, Markdown, summaries and translations return document content as text with no injection guidance (2). The container edition logs audit events; nothing documents per-call visibility for cloud accounts beyond usage counts (5). SOC 2 Type 2 through Datalogics' trust centre, HIPAA BAAs and a DPA, but no security.txt, disclosure policy or bug bounty found (12). 14 + 4 + 2 + 5 + 12 = 37.)
- Payments & pricing, pdfRest API Toolkit +15: ConvertAPI 25 (No x402, MPP or L402 (0). Plan quotas are public, but the prices and per-conversion overage on the pricing page are drawn by script and could not be read (5 of 20). A free trial of 250 conversions with no card, per llms.txt (20). A person signs up in a browser (0). 0+5+20+0 = 25.); pdfRest API Toolkit 40 (No x402, MPP or L402 (0). Plan prices, per-call overage, EU and Pro Tools per-call fees and file-size overage are on the public pricing page and in llms.txt (20). Starter is free with 100 calls a month and no card (20). A person signs up in a browser and the key is shown in the account (0). 0 + 20 + 20 + 0 = 40.)
- Maintenance & community, ConvertAPI +10: ConvertAPI 80 (Closed service. Newest changelog entry 5 November 2026 (30). Twelve dated entries from 1 October to 5 November (20). Public changelog, support email, phone and form, and SDK repositories on GitHub; issue replies not sampled (10 of 15). Current official SDKs, npm 1.16.0 on 26 October and PyPI 2.0.1 on 20 October 2026 (15). The MCP repository's last commit is 12 May 2026 and has no LICENSE file though its README says MIT; SDK CI not checked (5 of 10). 30+20+10+15+5 = 80.); pdfRest API Toolkit 70 (Read as a closed service. 2.56.7 released 14 October 2026 (30). Nine dated releases between 7 August and 14 October 2026 (20). Support through a Jira service desk and email on paid plans; Datalogics links a Discord; no public issue tracker for the API (10 of 15). Code samples in six languages are kept on GitHub, but no official SDK package was confirmed (5). The status repository's CI runs daily; nothing else to assess (5). 30 + 20 + 10 + 5 + 5 = 70.)
