API Reference

What authentication does Parse use?

Parse accepts two authentication methods: Bearer token (API key) and x402 USDC payment. Include your API key in the Authorization header for authenticated endpoints. Alternatively, use the x402 402 flow and retry with a payment-signature header. Legacy clients may still send x-payment.

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, adversarial patterns, and private-disclosure requests that require owner approval. This is the primary endpoint for prompt safety screening.

Auth required: Yes (scope: evaluate)

Request body

Response (200 OK)
