How this service works
Paid liveness probe for the MimirAPI counter. Returns pong, the SKU id, and a server timestamp. One tenth of a cent buys a complete challenge, sign, settle, serve round trip — the cheapest possible proof that your x402 client wiring works before you spend real money on real SKUs.
Output
A JSON object with three fields: `pong` (boolean true), `sku` (string identifier for the endpoint SKU), and `ts` (ISO-8601 server timestamp) — confirming a full x402 challenge, sign, settle, and serve round trip completed successfully for $0.001 USDC.
Example use cases
Example prompt
“Run the MimirAPI ping liveness probe to confirm my x402 client wiring works — I want to see the pong response, the SKU id, and the server timestamp back.”
Technical details
Endpoint
GEThttps://mimirapi.com/v1/pingWhen to prefer
Use this endpoint when you need the cheapest possible end-to-end validation that your x402 payment client is correctly wired — challenge, sign, settle, and serve — before committing real money to more expensive MimirAPI SKUs or other x402-enabled services. It is purpose-built as a developer smoke test for the x402 payment protocol.
Side effects
- Payment not provided or malformed x402 headers — server returns 402 Payment Required
- Insufficient USDC balance in wallet — payment settlement fails
- Incorrect x402 client configuration — challenge/sign step rejected
- Network timeout before settlement completes
- Invalid or expired payment challenge — 402 with re-challenge required
