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
Returns a watch_id and a capability URL you can poll anytime for free to get the current monitoring state. Additionally fires JSON POST webhooks to your specified URL whenever the endpoint flips state (up/down), latency changes significantly, or the advertised USDC price changes. Each check records uptime status, HTTP status code, latency, 402 shape correctness, and current price.
Example use cases
Monitor own x402 API uptime
“Keep an eye on my x402 endpoint at https://api.myservice.com/llm for the next 30 days — every 30 minutes check if it's up, returning proper 402s, and what USDC price it's advertising. Send any outages or price changes to my webhook at https://hooks.myapp.com/notify.”
Track competitor x402 pricing
“Watch https://api.competitor.xyz/prices every 30 minutes for 30 days and alert me at https://hooks.myapp.com/competitive-intel whenever their USDC price changes or the endpoint goes down.”
Validate x402 compliance before launch
“Before I go live, run a 30-day monitor on https://staging.myapp.com/x402-endpoint to make sure the 402 payment shape stays spec-compliant and latency stays reasonable — send failures to https://hooks.myapp.com/staging-alerts.”
Technical details
Endpoint
GEThttps://markets.losbeto.xyz/x402-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need long-running (30-day), automated monitoring of an x402-protocol endpoint specifically — tracking 402 shape compliance, USDC price changes, and uptime with webhook-driven alerting. Prefer it over generic uptime monitors when x402 protocol correctness and pay-per-call pricing surveillance are the primary concern.
Side effects
- Private or internal IP ranges refused — only public http/https URLs accepted
- Missing required 'url' or 'webhook' query parameters returns an error
- Invalid or unreachable webhook URL may result in missed alerts
- Non-x402 endpoints may still be monitored but 402 shape checks will fail
- Payment failure in USDC blocks the watch from being initiated
