Where Exa is ahead

Exa passes fast time to first request and copyable quickstart, and Replicate 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: rate-limit behavior predictable and agent compatibility verified. Replicate misses those.

What neither does

Both fail no mandatory sales call, agent-compatible signup flow, retry behavior documented, idempotency support. If your agent needs any of those, you will be building it yourself either way.
