How this service works
x402 hello-world: the cheapest live call on this node ($0.001), built for agents to smoke-test the full payment loop — 402 challenge, wallet signature, facilitator settlement, JSON delivery — against a real merchant....
Output
A signed JSON liveness receipt confirming the node is operational, the current node version string, and a structured map pointing to the free trial endpoint and the full paid catalog of Losbeto services. No upstream data calls are made; this is a pure local health-check response.
Example use cases
Smoke-test before market data pipeline
“Before my agent starts pulling crypto prices and forex data from Losbeto, run the $0.001 ping so I know the x402 payment loop is live and my wallet is correctly set up.”
Verify new wallet integration works
“I just configured a new Base wallet for USDC micropayments — can you fire the Losbeto ping endpoint for $0.001 to confirm the 402 challenge, signature, and facilitator settlement all complete without errors?”
Discover full Losbeto endpoint catalog
“Hit the Losbeto ping to get a liveness receipt and also pull back the map of all their available endpoints — I want to see what market data and LLM calls are available before I commit to anything.”
Technical details
Endpoint
GEThttps://api.losbeto.xyz/ping402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the absolute cheapest ($0.001) way to validate that the full x402 micropayment loop — challenge, signature, facilitator settlement, and JSON delivery — is functional before investing in more expensive Losbeto calls like LLM inference ($0.005) or market data. Prefer this over generic HTTP health checks when you specifically need to prove end-to-end payment flow, not just TCP reachability.
Side effects
- Insufficient USDC balance — payment settlement fails with 402 not resolved
- Wrong network — wallet on unsupported chain (not Base, Polygon, Solana, or Algorand)
- Facilitator timeout — 402 challenge issued but settlement confirmation not received in time
- Node downtime — endpoint returns 5xx if Losbeto node is offline
- Invalid wallet signature — 402 challenge response rejected by facilitator
