What Exa does that OpenRouter does not

Exa passes search discoverable, public docs discoverable, mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk, cli available, mcp integration available, canonical workflow succeeds, structured, predictable output, machine-readable errors, rate-limit behavior predictable, observable execution, and OpenRouter 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

OpenRouter fails search discoverable, public docs discoverable, mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk, official python sdk, cli available, mcp integration available, canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.

Where OpenRouter loses the points

Pillar	OpenRouter	What it measures
Discover	100	Can an agent find it at all: sitemap, robots, structured data.
Understand	92	Is there a spec, an llms.txt, a machine-readable description.
Adopt	88	Signup, keys, SDKs, and whether a human has to be involved.
Operate	44	Rate-limit headers, errors, status, and behaviour under load.

OpenRouter is weakest on operate at 44/100. Missing rate-limit headers mean an agent finds the limit by hitting it. If that is the part your agent depends on, take the ranking above seriously; if it is not, OpenRouter may still be the right pick.
