How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
Returns a JSON object with: ok (boolean health status), t (ISO-8601 timestamp), paymentVerified (boolean confirming x402 USDC payment processed), receiptId (payment receipt string), testRunId (echoed correlation ID), next (array of sibling endpoint paths available to call), and nextAction hint string.
Example use cases
Agent boot self-check before trading
“At startup, run a quick ping against the crypto microdata API with test run ID 'boot-run-001' so I can confirm my x402 wallet payment is working and see which data endpoints are available to call.”
CI validation of x402 payment pipeline
“Run a connectivity and payment verification ping on the crypto microdata service with echo tag 'ci-test-42' so I can confirm the x402 micropayment flow is healthy in our staging pipeline.”
Discover available crypto data routes
“Hit the crypto microdata ping endpoint so I can see what paid data routes are available — things like Base gas, token risk scores, Hyperliquid book data, and kimchi premium — before I decide which ones my agent needs.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/x402/ping?utm_source=zero.xyzWhen to prefer
Use this endpoint as the first call when bootstrapping a trading or onchain AI agent: it simultaneously verifies that the agent's x402/USDC micropayment stack is functional, returns a payment receipt for accounting, and provides a discovery manifest of available paid data endpoints — all for $0.001 USDC. Prefer it over hitting paid data endpoints directly when you need to confirm connectivity or payment plumbing before committing to more expensive calls.
Side effects
- Payment not received or insufficient USDC balance → 402 Payment Required with x402 challenge
- Invalid or malformed echo/testRunId (exceeds maxLength) → 400 Bad Request
- Worker cold-start latency spike → increased response time but no error
- Base network congestion delaying payment settlement → payment verification timeout
- Worker region outage → 503 Service Unavailable
