How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
Returns a JSON object indicating whether a change was detected (changed: true/false), the type of check performed (check: 'change_detection'), and the product identifier (product: 'GENESIS* Watch').
Example use cases
Price drop monitoring for products
“I had a product price recorded as $29.99 yesterday, and today it shows $24.99 — can you check if it actually changed?”
Config drift detection in automation
“My config setting was previously 'enabled: false' and now it's 'enabled: true' — run a change check and tell me if something shifted.”
Data pipeline state verification
“Before I trigger the next pipeline step, verify whether the record changed — previous state was 'pending' and current is 'processed'.”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/watch_change_detect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call change detection utility that integrates with x402 micropayment flows on Base USDC. It is ideal for autonomous agents that need to compare two discrete states without maintaining stateful monitoring infrastructure. Prefer this over webhook-based monitoring when you already have both previous and current values in hand and need a single deterministic comparison result.
Side effects
- Missing required 'previous' or 'current' fields in body causes validation error
- Malformed JSON body results in request rejection
- Payment failure via x402/USDC blocks request execution
- Non-POST method returns method not allowed error
- Network timeout on the Cloudflare Worker edge node
