It also holds understand: limits / constraints documented. Selectpdf misses it.

And on adopt, agent-compatible signup flow, cli available and mcp integration available. Selectpdf misses those.

Finally, on operate, structured, predictable output and agent compatibility verified. Selectpdf misses those.

Where Selectpdf is ahead

Selectpdf passes clear product positioning, and Galileo does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: pricing understandable. Galileo misses it.

And on adopt, self-service signup, free trial or free allowance and fast time to first request. Galileo misses those.

What neither does

Both fail structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution. If your agent needs any of those, you will be building it yourself either way.
