Technical details
Endpoint
GEThttps://quietstore-production.edge-7e13f.workers.dev/v1/packs/x402-retry-safe-seller-v1When to prefer
Choose this endpoint when you need a concrete, production-tested reference for implementing an x402-compliant seller endpoint that safely handles agent retries and avoids double-billing. Prefer it over generic HTTP 402 documentation when you need Base USDC-specific patterns, ledger idempotency guidance, or buyer recovery message templates.
Side effects
- Payment not received or 402 not resolved — endpoint returns 402 requiring USDC payment before content is served
- Invalid pack identifier — returns 404 if the pack name does not match a known playbook
- Network or worker error — Cloudflare edge worker may return 500 or 503 transiently
- Expired or stale payment facilitator — facilitator may reject payment if configuration is outdated
