What each one is

Api2Pdf. A REST API for generating PDFs and Office documents from HTML, URLs, Microsoft Office Documents (Word, Excel, PPT), Email files, and images.

PDF.co. PDF.co is a low-code REST API platform for automating PDF conversion, editing, extraction, and more.

Where Api2Pdf is ahead

Api2Pdf passes agent compatibility verified, and PDF.co does not. That is operate, whether an agent can run against it in production and recover when a call fails.

Where PDF.co is ahead

PDF.co passes llms.txt published and llms-full.txt / full agent docs, and Api2Pdf does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: openapi / spec quality, request examples provided and errors and status codes documented. Api2Pdf misses those.

And on adopt, agent-compatible signup flow, programmatic credential creation and cli available. Api2Pdf misses those.

Finally, on operate, structured, predictable output, machine-readable errors and observable execution. Api2Pdf misses those.

What neither does

Both fail response examples provided, limits / constraints documented, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
