API Reference
What authentication does ParseThis.ai use?
ParseThis.ai accepts two authentication methods: Bearer token (API key) and x402 USDC payment. Include your API key in the Authorization header for all authenticated endpoints. Alternatively, attach an X-PAYMENT header with a signed USDC transfer on Base L2 — no API key needed.
Authorization: Bearer pfa_live_...Generate an API key at POST /v1/keys/generate (no auth required). Keys expire in 30 days and have scopes: analyze, evaluate, chat.
POST /v1/parse
Screen a prompt for injection attacks, jailbreaks, and adversarial patterns. This is the primary endpoint for prompt safety screening.
