# Stock x402: RSL rights before RAG ingestion and AI training

`POST /v1/rights/preflight/x402`

## Request

- Base URL: `https://api.getacqpath.com`
- URL: `https://api.getacqpath.com/v1/rights/preflight/x402`
- Auth: none declared

RSL rights before RAG ingestion, AI input, training and search. Stock x402 v2 EIP-3009 fresh Rights Preflight, 0.02 USDC on Base. One authorization binds one request on first valid use; no SIWX, no pre-signature body binding. Reviewed origins only. Diagnostic report, not a license or legal clearance. First unpaid valid POST returns a 402 without source work. No verifiable declaration after authorized observation means no settlement; that authorization remains bound to this attempted input. Preserve the exact signed retry privately for recovery. Secure SIWX remains recommended when supported.

## Request body
