AI-readable files

PDF4.dev provides machine-readable documentation files for AI agents that browse or ingest docs rather than using the MCP server.

llms.txt

A short overview of PDF4.dev: what it does, the main endpoints, and links to further resources. Follows the llms.txt spec.

https://pdf4.dev/llms.txt

Use this when you want an agent to quickly understand what PDF4.dev is and what it can do, without ingesting the full API reference.

llms-full.txt

Complete API documentation in plain markdown: all endpoints, request/response schemas, authentication, error codes, and cURL examples. Designed for agents that need full context to write integration code.

https://pdf4.dev/llms-full.txt

When to use: provide this file to your agent when asking it to write integration code, build a wrapper, or debug API calls.

agents.md

Agent-specific instructions: how to authenticate, which tools to use for which tasks, error handling, and primary actions. Follows the agents.md spec.

OpenAPI spec

The full OpenAPI 3.1 specification, usable by any tool that supports it (Postman, code generators, type-safe clients):

https://pdf4.dev/api/v1/openapi.json

Keeping agents updated

These files are kept in sync with every API change. If you cache them locally, refresh them periodically to pick up new endpoints or changed schemas.
