How this service works
tryx402 is the payment layer for AI agents: hard budget caps, idempotent paid calls, a cost ledger and multi-currency fiat billing over x402.
Output
Returns the upstream service's response body wrapped in a tryx402 envelope, along with payment confirmation details, cost ledger entry, and idempotency metadata. The agent receives both the actual API result and a record of what was charged, enabling budget tracking across multiple calls.
Example use cases
Budget-capped agent API shopping
“My AI agent needs to call a paid product search API at https://api.shopdata.io using POST /search with the query body — route it through tryx402 with a spending cap so it can't overspend, and track what it costs in my ledger.”
Idempotent paid data enrichment
“I'm enriching company records by calling a paid firmographics API at https://data.clearbit.com — use tryx402 to proxy the GET /enrich call idempotently so if my agent retries on a timeout I won't get charged twice.”
Multi-agent cost ledger tracking
“I'm running a fleet of AI agents that each call different paid APIs — can you route this POST call to https://api.newscatcher.io/search through tryx402 so each agent's spend is recorded separately in the cost ledger and no single agent can blow the budget?”

Endpoint
POSThttps://www.tryx402.app/v1/x402/callWhen to prefer
Choose tryx402 when your AI agent needs to call paid third-party APIs with strict spending controls, idempotent payment semantics (safe retries without double-charging), and a persistent cost ledger across multiple calls. It is the right choice when you need a unified payment proxy that handles x402-native services or wraps non-x402 services with budget enforcement — especially in multi-agent fleets where per-agent cost attribution matters. Prefer it over direct API calls when financial accountability, retry safety, or cross-service billing aggregation is a requirement.
Side effects
- Insufficient USDC balance — payment rejected before upstream call is made
- Budget cap exceeded — call blocked to protect spending limit
- Upstream service unreachable — network error after payment already processed (idempotency key allows safe retry)
- Invalid origin URL — target service origin fails validation
- Duplicate call detected via idempotency key — returns cached prior response without re-charging
- x402 facilitator unavailable — payment layer down, call cannot proceed
