What each one is

It also holds adopt: official python sdk. Redocly misses it.

Where Redocly is ahead

Redocly passes clear canonical domain, public docs discoverable and machine-readable metadata, and Pylon 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 and pricing understandable. Pylon misses those.

And on adopt, self-service signup, agent-compatible signup flow and free trial or free allowance. Pylon misses those.

Finally, on operate, structured, predictable output. Pylon misses it.

What neither does

Both fail llms-full.txt / full agent docs, 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, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. 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.

Operate. Redocly leads 65 to 53. Pylon misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Redocly misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.
