Technical details
Endpoint
POSThttps://x402-agent-suite-production.up.railway.app/api/quality-escrow/settle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to finalize an x402 quality escrow — i.e., after a paid service call has completed and you want to programmatically decide whether the escrowed USDC should be released to the provider based on a quality score threshold. Prefer this over general refund or payment endpoints when the escrow decision is quality-driven rather than dispute-driven.
