# Parsa

> Parsa (Parsa Labs) is an anti-bot solver API at https://api.parsalabs.io. A client sends the challenge a site served it (a script, a challenge page, cookies) and gets back the payload a browser would have sent, then posts that payload itself, from its own IP. No browser runs on either side. It covers Akamai Bot Manager, DataDome, Imperva Incapsula, PerimeterX (HUMAN) and Queue-it BotDeflector. Pricing is per successful solve, prepaid in euros: only HTTP 200 answers are billed.

Authentication: `Authorization: Bearer parsa_…` (or `x-api-key`). Keys are created in the dashboard at https://parsalabs.io/dashboard; balance is prepaid from €5, with no plan or monthly fee. Errors (4xx, 5xx, unknown script builds, timeouts) cost nothing. A 409 unknown_build asks for the script once more. A 503 carries Retry-After.

The client must keep one TLS fingerprint, header order, user agent, exit IP and cookie jar per session, and pass that IP and Accept-Language to the API: the payload describes a device consistent with them.
