Endpoint

POSThttps://x402trustlayer.xyz/api/trust-network/transaction-auth?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to verify whether an HTTP request is authorized within the x402 trust network ecosystem, particularly after a USDC micropayment has been settled. Best suited for agents operating within x402-based access control flows needing a guard check on GET, HEAD, or DELETE methods.

Side effects

Payment not settled — transaction blocked, allowed returns false
Invalid HTTP method provided (only GET, HEAD, DELETE supported)
Missing required 'type' or 'method' fields returns 400 validation error
x402 network unavailable causes timeout or 5xx error
Insufficient USDC balance prevents payment and blocks authorization
