Exa scores higher on the AgentReady, 92/100 against 80/100. They differ on 20 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Anthropic. Anthropic is a public benefit corporation dedicated to securing the benefits of AI and mitigating its risks.

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 Exa is ahead

Exa passes search discoverable, clear product positioning, public docs discoverable and llms-full.txt / full agent docs, and Anthropic does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented. Anthropic misses those.

And on adopt, programmatic credential creation, fast time to first request, copyable quickstart, official typescript sdk and official python sdk. Anthropic misses those.

Finally, on operate, canonical workflow succeeds, structured, predictable output, machine-readable errors, rate-limit behavior predictable and observable execution. Anthropic 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.
