Cohere vs Exa

Exa scores higher on the AgentReady, 92/100 against 49/100. They differ on 19 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Cohere. Cohere is an AI company providing enterprise-ready AI solutions that keep data and infrastructure under customer control.

Exa. Exa is a custom search engine built for AIs, offering an API to search the largest index of public web and private information.

Where Cohere is ahead

Cohere passes agent-compatible signup flow, and Exa does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

Where Exa is ahead

Exa passes mcp discoverable, and Cohere does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented. Cohere misses those.

And on adopt, self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, cli available and mcp integration available. Cohere misses those.

Finally, on operate, machine-readable errors, rate-limit behavior predictable and agent compatibility verified. Cohere misses those.

What neither does

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