How this service works
Pay-per-call rug check for crypto smart contracts. Built for AI agents on Agentic.market (x402). USDC fractional pricing, no API key.
Output
Returns a watch_id, HMAC secret (store securely — only returned once), expiry timestamp, subscribed event types, check interval, and USDC cost settled. The HMAC secret is used to verify the X-RugGuard-Signature header on all incoming webhook POSTs from RugGuard.
Example use cases
Example prompt
“Set up a rug-pull watch on Ethereum contract 0xAbC123... and send alerts to https://mybot.example.com/rugalert — check every 60 seconds and keep the watch alive for 24 hours.”
Technical details
Endpoint
POSThttps://rugguard.redfleet.fr/v1/watch/%7Bchain%7D/%7Bcontract%7DWhen to prefer
Choose this endpoint when you need ongoing, automated monitoring of a smart contract rather than a one-time pre-trade check. Ideal for AI agents that hold or track positions and need webhook-driven alerts if a contract's risk profile changes over time. Use the single-call check endpoint for a quick pre-trade scan; use this watch endpoint when you want persistent surveillance with auto-expiry and HMAC-verified callbacks.
Side effects
- Invalid or non-existent contract address — 400 or 422 validation error
- Unsupported chain identifier — 400 bad request
- webhook_url missing or not HTTPS in production mode — 422 validation error
- Payment failure or insufficient USDC balance — 402 payment required
- Watch TTL or interval values out of acceptable range — 422 validation error
- Webhook endpoint unreachable — may create watch but first delivery fails silently
