How this service works
We score x402 endpoints, then try to buy from every gated one with real USDC. The only directory that buys from its own listings. Live counts from /v0/stats.
Output
Returns a JSON object confirming the subscription was created, including: ok (boolean), active (boolean), seller name, a unique sub_id (UUID), and the monitoring term in days (typically 30).
Example use cases
Daily uptime monitoring for x402 API
“Add my x402 endpoint at https://api.myproduct.com/v1/report to the RobotsShop Trust Index for daily monitoring — it accepts POST requests with a JSON body, and if it ever fails a payment test, send an alert to https://hooks.myproduct.com/alerts.”
Trust index enrollment for new x402 seller
“I just launched an x402-gated endpoint at https://api.startupxyz.io/generate and I want RobotsShop to score and monitor it daily — it's a POST with JSON, and my settlement payTo address is 0xABC123. My contact email is founder@startupxyz.io.”
Webhook alert setup for payment failure detection
“Register https://api.databroker.net/premium/fetch with RobotsShop's daily trust monitoring — it's a POST endpoint with a JSON body, and I want webhook notifications sent to https://databroker.net/webhooks/rs whenever a real USDC purchase attempt fails.”
Technical details
Endpoint
POSThttps://api.robotsshop.io/v0/monitor/subscribeWhen to prefer
Choose this endpoint when you want your x402-gated seller endpoint actively monitored and scored by the only directory that tests its own listings with real USDC purchases. Prefer this over generic uptime monitors when you specifically want x402 protocol compliance validated, trust scored, and listed in the RobotsShop Trust Index. Ideal for x402 API operators who want independent third-party verification that their payment-gated endpoints actually work end-to-end.
Side effects
- Missing required 'url' field in body — returns validation error
- Invalid URL format — returns schema validation failure
- Unsupported HTTP method (not POST/PUT/PATCH) — returns enum validation error
- Invalid webhook URL format — returns URI validation error
- Payment not completed — x402 payment of $10 USDC required before subscription is activated
- Duplicate subscription for same URL — may return conflict or existing subscription
- Unreachable endpoint URL — monitoring may start but immediately flag as unreachable
