Where Crawlbase is ahead

Crawlbase passes agent-compatible signup flow, fast time to first request and copyable quickstart, and Jina AI does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

It also holds operate: agent compatibility verified. Jina AI misses it.

Where Jina AI is ahead

Jina AI passes structured api reference, openapi / spec quality, request examples provided, response examples provided and errors and status codes documented, and Crawlbase does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail no mandatory sales call, idempotency support. If your agent needs any of those, you will be building it yourself either way.
