It also holds understand: authentication documented. Capsolver misses it.

And on adopt, fast time to first request, copyable quickstart, cli available and mcp integration available. Capsolver misses those.

Finally, on operate, agent compatibility verified. Capsolver misses it.

What neither does

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