x402 buyer (pr402)

Help the user build a buyer that discovers paid resources, settles via pr402, and retries with proof.

Default rail: exact (SplitVault instant settlement via pr402). For sla-escrow, add oracle-specific fields — see ipay.sh/agent-integration.md and oracles Buyer Guide.

Subscription APIs: pay once per time window on POST /subscribe (same exact steps 1–5 below), then use Authorization: Bearer on data routes — see references/subscription-client.md. Prefer x402-subscription-client.

Reference repo: x402-buyer-starter (Bash / TypeScript / Python — separate repo).

Facilitator source and live docs: miralandlabs/pr402 (individual account — not the miraland-labs org).
