How this service works
OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.
Output
A JSON object containing a signed liveness receipt (proving the full x402 payment loop completed), the current node version, a pointer to the free trial, and a map of the full Losbeto endpoint catalog. No upstream calls are made; response is generated locally by the node.
Example use cases
Pre-flight agent wallet check
“Before I send my agent into production, run the $0.001 Losbeto ping to make sure its Base wallet can actually complete the full x402 payment loop — I need a signed receipt back as proof.”
x402 integration smoke test
“I just wired up x402 USDC payments to my agent — can you hit the Losbeto /ping402 endpoint to do a live end-to-end test of the 402 challenge and facilitator settlement for just $0.001?”
Discover Losbeto catalog cheaply
“Use the Losbeto ping call to get the node version and a map to all the market data and LLM endpoints available, and confirm everything is live — it should only cost a tenth of a cent in USDC.”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/ping402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the absolute cheapest ($0.001 USDC) live end-to-end test of an x402 payment pipeline against a real merchant node. It is the canonical smoke-test call for agents integrating x402 micropayments — use it to validate wallet configuration, chain support, facilitator connectivity, and JSON delivery before committing to higher-cost calls on the same node. Prefer it over other liveness checks when you specifically need a signed receipt proving payment completed.
Side effects
- Insufficient USDC balance in agent wallet — payment rejected before data is returned
- Unsupported blockchain network — payment attempted on a chain not supported (only Base, Solana, Algorand, Polygon accepted)
- Facilitator settlement failure — 402 challenge completed but facilitator cannot confirm payment
- Invalid format query param — unexpected value causes malformed request
- Node downtime — merchant node offline, no 402 challenge issued
