How this service works
Select an exactly compatible x402 v2 requirement without receiving private keys
Output
A selected, exactly compatible x402 v2 payment requirement object that the calling agent can use to satisfy the payment gate of a target API, without any private key material being transmitted or exposed in the process.
Example use cases
Pre-call payment requirement matching
“Before my agent calls this paid API, can you use the x402 v2 router to find the right payment requirement that matches what I support, without sending my private keys anywhere?”
Multi-option x402 requirement selection
“My agent is about to hit an x402-protected endpoint and got back multiple payment options — can you route it through the x402 v2 router to select the exactly compatible v2 requirement?”
Safe payment routing in autonomous pipeline
“I'm building an autonomous agent workflow that calls x402-gated APIs — use the x402 v2 router to handle payment requirement selection at each step so private keys are never transmitted.”
Technical details
Endpoint
POSThttps://phion.systems/v1/paid/trust/x402-v2-router?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to automatically select a compatible x402 v2 payment requirement before calling a paid API, especially when security is a priority and private keys must never leave the agent's secure context. Prefer this over manual payment negotiation or generic payment routers when you need deterministic x402 v2 compatibility matching with a signed, trustworthy selection outcome.
Side effects
- No compatible x402 v2 requirement found for the given input — returns an error or empty selection
- Malformed or missing input schema fields cause a validation error
- The target payment requirement version is not v2 — incompatible and not matched
- Service returns an error if the request exceeds rate limits or the $0.003 USDC fee is not settled
