Crawlbase vs Extract

Extract scores higher on the AgentReady, 71/100 against 68/100. They differ on 16 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Crawlbase. Crawlbase provides web crawling, scraping, and parsing APIs at scale.

Extract. Vend API Merchant — Six pay-per-call APIs for AI agents settled in Nano (XNO), no signup, no API key.

Where Crawlbase is ahead

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

It also holds understand: limits / constraints documented. Extract misses it.

And on adopt, agent-compatible signup flow, fast time to first request and copyable quickstart. Extract misses those.

Finally, on operate, observable execution and agent compatibility verified. Extract misses those.

Where Extract is ahead

Extract passes structured api reference, response examples provided and errors and status codes documented, and Crawlbase does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: no mandatory sales call and programmatic credential creation. Crawlbase misses those.

And on operate, structured, predictable output, machine-readable errors and retry behavior documented. Crawlbase misses those.

What neither does

Both fail openapi / spec quality, request examples provided, 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.

Discover. Crawlbase leads 100 to 80. Crawlbase misses nothing; Extract misses public docs discoverable, llms-full.txt / full agent docs.

Operate. Both sit at 53/100 here. Crawlbase misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Extract misses idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.
