What PDF.co does that Documint does not
PDF.co passes mcp discoverable, structured api reference, openapi / spec quality, authentication documented, request examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, cli available, mcp integration available, structured, predictable output, machine-readable errors, observable execution, and Documint 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
Documint fails mcp discoverable, structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, cli available, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Documint loses the points
| Pillar | Documint | What it measures |
|---|---|---|
| Discover | 87 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 23 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 62 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 24 | Rate-limit headers, errors, status, and behaviour under load. |
Documint is weakest on understand at 23/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Documint may still be the right pick.
What an agent runs into with Documint
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.
- Ship an MCP server so agents can call you as a tool.
- Publish MCP install instructions so agents can discover the server.
- Publish an OpenAPI spec so agents can generate a client.
- 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.
An agent can get this list directly: resolve("alternative to Documint") over the MCP server, or GET /v1/categories/pdf-documents.
