Beam vs Exa

Exa scores higher on the AgentReady, 92/100 against 52/100. They differ on 13 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Beam. Serverless GPU cloud platform for running AI inference, agents, and task queues with sub-second cold starts.

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 mcp discoverable, and Beam 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, authentication documented, request examples provided, response examples provided and errors and status codes documented. Beam misses those.

And on adopt, programmatic credential creation and mcp integration available. Beam misses those.

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

What neither does

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

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Exa leads 100 to 87. Beam misses mcp discoverable; Exa misses nothing.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Exa leads 100 to 31. Beam misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented; Exa misses nothing.

Adopt. Exa leads 81 to 55. Beam misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, mcp integration available; Exa misses no mandatory sales call, agent-compatible signup flow.

Operate. Exa leads 88 to 35. Beam misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified; Exa misses retry behavior documented, idempotency support.
