All scored in Web Search & Research.
What Exa does that Valyu does not
Exa passes structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, machine-readable errors, rate-limit behavior predictable, observable execution, agent compatibility verified, and Valyu 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.
Why people look for an alternative
Valyu fails structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, agent-compatible signup flow, programmatic credential creation, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
