What PDF.co does that Api2Pdf does not
PDF.co passes llms.txt published, llms-full.txt / full agent docs, openapi / spec quality, request examples provided, errors and status codes documented, agent-compatible signup flow, programmatic credential creation, cli available, structured, predictable output, machine-readable errors, observable execution, and Api2Pdf fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Api2Pdf fails llms.txt published, llms-full.txt / full agent docs, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, cli available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Api2Pdf loses the points
| Pillar | Api2Pdf | What it measures |
|---|---|---|
| Discover | 87 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 46 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 75 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 41 | Rate-limit headers, errors, status, and behaviour under load. |
Api2Pdf is weakest on operate at 41/100. Missing rate-limit headers mean an agent finds the limit by hitting it. If that is the part your agent depends on, take the ranking above seriously; if it is not, Api2Pdf may still be the right pick.
What an agent runs into with Api2Pdf
These are the findings from the last audit on 2026-08-23. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
- Return request IDs and expose status/usage so runs are observable.
- Add /llms.txt so agents can find and read your capabilities.
- Publish an AGENTS.md or llms-full.txt with full agent context.
- Add request examples to your API reference.
An agent can get this list directly: resolve("alternative to Api2Pdf") over the MCP server, or GET /v1/categories/pdf-documents.
