What Exa does that Cerebras does not
Exa passes clear canonical domain, llms-full.txt / full agent docs, structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, cli available, structured, predictable output, machine-readable errors, rate-limit behavior predictable, agent compatibility verified, and Cerebras fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
