What each one is

Where Pinecone is ahead

Pinecone passes llms-full.txt / full agent docs and mcp discoverable, and Selectpdf does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented. Selectpdf misses those.

And on adopt, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, cli available and mcp integration available. Selectpdf misses those.

Finally, on operate, structured, predictable output, machine-readable errors, observable execution and agent compatibility verified. Selectpdf misses those.
