It also holds adopt: cli available and mcp integration available. OpenRouter misses those.

Where OpenRouter is ahead

OpenRouter passes clear product positioning 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. Anthropic misses it.

What neither does

Both fail search discoverable, public docs 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, canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution. 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.
