Relay x402
Abstract commerce network with verification, routing, and ledger paths
Live on Stellar testnet

Verified commerce infrastructure for autonomous agents.

Relay lets agents discover machine-payable services, verify whether they work, route by policy, pay over Stellar x402, and produce auditable commerce receipts.

What Relay does

Relay is not a wallet or a new payment protocol. It is the trust, discovery, routing, and audit layer around standard Stellar x402 payments.

Payment

Stellar x402 facilitator

Standard /supported, /verify, and /settle compatibility through a Stellar x402 facilitator.

Discovery

Bazaar-compatible catalog

Services expose capability, schema, endpoint, provider, network, asset, and price metadata.

Verification

Health and price evidence

Relay models liveness, payment-interface health, latency, pricing consistency, confidence, and reliability.

Routing

Deterministic provider choice

Agents express constraints. Relay filters and ranks providers without asking an LLM to decide financial policy.

Policy

Machine spending controls

Budget, network, asset, reliability, latency, confidence, and provider rules are evaluated as hard constraints.

Receipts

Auditable commerce trail

Receipts connect request intent, selected provider, routing reason, payment metadata, and response hash.

Discoverable services

Relay starts with Atlas, a paid Stellar RWA intelligence service, plus comparable providers that exercise policy-aware routing and failover.

Policy-aware routing

Try a live route request: inspect a Stellar RWA under $0.005, on USDC, with at least 99% reliability. Relay returns the selected service, fallbacks, and rejection reasons.

How to use Relay

Everything public is HTTPS and machine-readable. Agents can discover, route, and then call x402-protected resources.

1. Check x402 support

curl https://api.relayx402.xyz/x402/supported

2. Route by capability

curl -X POST https://api.relayx402.xyz/v1/routes \
  -H 'content-type: application/json' \
  -d '{"capability":"rwa.asset.inspect","constraints":{"networks":["stellar:testnet"],"assets":["USDC"],"maxPricePerRequestUsd":0.005,"minProviderReliability":0.99},"optimizeFor":"balanced"}'

3. Call the paid service

curl -i -X POST https://atlas.relayx402.xyz/atlas/v1/rwa/inspect \
  -H 'content-type: application/json' \
  -d '{"asset":"C..."}'

4. Inspect catalog data

curl https://api.relayx402.xyz/v1/resources

Capability clusters

Relay is designed around agent intent instead of hard-coded vendor integrations.
