Agent commerce, verified on Stellar.
The x402 facilitator that enforces the buyer's spending policy at settlement, using independent verification of the seller.
The operating layer around machine payments.
Relay settles standard Stellar x402 payments. What it adds is a refusal: a payment that breaks the buyer's declared policy does not settle — decided on the settlement path, where a compromised agent cannot route around it.
Relay is the facilitator
Relay settles on-chain itself through /verify and /settle, sponsoring network fees so buyers need no XLM.
Bazaar-compatible catalog
Capability, endpoint, provider, schema, network, asset, and price metadata in a machine-readable index.
Evidence, not listings
Relay tracks liveness, payment-interface validity, price consistency, latency, reliability, and confidence.
Provider choice by policy
Agents express constraints. Relay filters, ranks, and explains which providers qualify or fail.
Hard spend limits
Network, asset, price, reliability, confidence, latency, and provider rules are evaluated deterministically.
Auditable commerce trail
Receipts connect intent, selected service, route reasoning, payment metadata, and response hash.
From intent to paid result.
The agent does not need to hard-code a vendor. It asks for a capability, then Relay resolves the safest eligible purchase path.
Capability search
Search Relay for resources matching capability, network, asset, schema, and budget.
Payment-interface verification
Check that the service is alive and returns valid Stellar x402 payment requirements.
Policy-aware route
Reject providers that exceed price, reliability, latency, confidence, network, or asset rules.
Standard x402 payment
The buyer signs locally, Relay verifies and settles, and the provider returns the paid response.
Commerce receipt
Create a durable record linking request intent, provider selection, transaction evidence, and result hash.
Live infrastructure signals.
The current public environment is testnet-first while mainnet operations are prepared separately.
Discoverable services.
Relay starts with Atlas, a paid Stellar RWA intelligence service, plus comparable provider records for routing and failover behavior.
| Service | Capability | Price | Status | Endpoint |

Policy-aware routing, live.
POST /v1/routes
Click Run route to evaluate every indexed
provider against the constraints on the left.
Relay returns the selection, the fallbacks,
and the reason each rejected provider failed.Use Relay from any agent stack.
Everything public is HTTPS and machine-readable. Agents can discover, route, then call x402-protected resources.

Relay is designed around capabilities, not vendor lock-in.
Ship an agent that can pay for itself.
Point your agent at the catalog, express a policy, and let Relay resolve the safest provider on Stellar testnet.
