How this service works
24 paid x402 infrastructure APIs for AI agent fleets: buy advisor, audition coach, guard, proxy, MPP, attestations, and pipeline orchestration.
Output
A JSON object containing a boolean 'ok' field indicating request success, a boolean 'allowed' field indicating whether the route is permitted, and a 'summary' string describing the routing decision outcome after x402 payment settlement.
Example use cases
Agent fleet request gating
“Before my agent fleet sends out GET requests to external APIs, run them through the rail optimizer to check if each one is allowed and get a routing summary back.”
Pre-flight route validation
“I need to validate whether a HEAD request is permitted by the x402 route optimizer before my agent actually dispatches it — can you check and tell me if it's allowed?”
Safe DELETE authorization check
“My agent is about to fire a DELETE request — can you run it through the x402 rail optimizer first to confirm the route is authorized and get a summary of the decision?”
Technical details
Endpoint
POSThttps://x402-agent-suite-production.up.railway.app/api/rail-optimizer/route?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, x402-native route authorization check specifically for idempotent HTTP methods (GET, HEAD, DELETE) within an AI agent fleet context. It is ideal when you want a fast allow/deny routing decision with a human-readable summary before dispatching requests, and when your infrastructure already integrates with x402 payment flows. Prefer it over generic API gateways when operating within the x402 ecosystem and needing per-call micropayment-gated routing decisions.
Side effects
- Payment settlement failure if x402 USDC payment of $0.04 is not completed, returning a 402 Payment Required response
- Invalid HTTP method supplied (only GET, HEAD, DELETE are accepted) returns a 400 or validation error
- Missing required 'input' object or 'type'/'method' fields causes schema validation failure
- Network timeout or Railway infrastructure downtime results in a 503 or connection error
- Unsupported request type (not 'http') causes const validation rejection
