Crawlbase vs ScraperAPI

Crawlbase scores higher on the AgentReady, 68/100 against 66/100. They differ on 4 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.

ScraperAPI. ScraperAPI is a web scraping API service that allows users to collect data from any public website without worrying about proxies, browsers, or CAPTCHA handling.

Where Crawlbase is ahead

Crawlbase passes limits / constraints documented, and ScraperAPI 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: official python sdk and cli available. ScraperAPI misses those.

Where ScraperAPI is ahead

ScraperAPI passes structured api reference, and Crawlbase does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, structured, predictable output, 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.

Understand. ScraperAPI leads 46 to 38. Crawlbase misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented; ScraperAPI misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt is whether an agent can get a key and make its first successful call without a human in the loop. Crawlbase leads 81 to 65. Crawlbase misses no mandatory sales call, programmatic credential creation; ScraperAPI misses no mandatory sales call, programmatic credential creation, official python sdk, cli available.

Operate. Both sit at 53/100 here. Crawlbase misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; ScraperAPI misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable.

Pricing

Crawlbase does not publish a machine-readable starting price and has a free tier. ScraperAPI does not publish one with no free tier.
