How this service works
Robinhood Chain address watcher: register an https callback and we POST to it whenever the address has a new ERC-20 transfer (60s polling, persisted). Agent-infra: stop polling, get pushed. Send { address, callbackUrl }.
Output
A confirmation that the watch has been registered, linking the specified address to the provided callback URL. Subsequently, whenever a new ERC-20 transfer is detected for that address (checked every 60 seconds), the registered callback URL receives a POST with transfer event details including the address and transfer data.
Example use cases
Payment confirmation for commerce agent
“As soon as the address 0x1234...abcd on Robinhood Chain receives any ERC-20 token transfer, POST a notification to https://shop.mysite.com/api/payment-received so I can automatically confirm the order.”
DeFi yield deposit watcher
“Keep an eye on my vault address 0xDEAD...BEEF on Robinhood Chain and push an alert to https://alerts.mybot.io/defi-deposit whenever a new ERC-20 comes in — I want to know the moment funds hit.”
Agent-to-agent settlement detection
“Register a watch on Robinhood Chain address 0xF00...B4R and call back https://orchestrator.internal/settlement-hook each time there's a new ERC-20 transfer, so the downstream agent knows it's been paid and can proceed.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/rhchain/watchWhen to prefer
Choose this endpoint when you need event-driven notifications for ERC-20 transfers on Robinhood Chain without implementing your own polling loop. It is ideal for AI agents and automated pipelines that need to react to on-chain payment or token events without maintaining persistent connections or polling infrastructure. Prefer this over general-purpose blockchain RPC polling when you want a managed, persistent watcher with webhook delivery semantics on Robinhood Chain specifically.
Side effects
- Invalid or malformed EVM address returns an error
- Unreachable or invalid callback URL may fail silently or return an error at registration
- Duplicate registrations for the same address/callback pair may create duplicate notifications
- The 60-second polling window means events are not truly real-time, only near-real-time
- Service restarts could lose in-flight polling state before persistence is confirmed
- Payment of 0.01 USDC not included or failing causes request rejection
