How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
A JSON object with an 'ok' boolean field indicating whether the change detection operation completed successfully, plus any detected change metadata.
Example use cases
Monitor product price API for changes
“Watch this product pricing API endpoint and let me know if the response changes — POST to it with this JSON body and flag any differences.”
Detect website content updates
“Check if the content returned by this endpoint has changed since the last time we looked — use a POST request with the form-data body I gave you and tell me if it's different.”
Track API state changes for automation
“I need to know if this internal API's state has shifted — send a POST with this JSON payload and report back whether the response looks different from the baseline.”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/change-detectWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call change detection signal for HTTP-accessible resources without managing your own polling infrastructure. Best suited for agents that need to autonomously detect state changes on APIs or web endpoints and can pay $0.01 USDC per check via x402 multi-chain payment rails.
Side effects
- Missing required 'input' or 'output' fields returns a validation error
- Invalid HTTP method (e.g. GET instead of POST/PUT/PATCH) rejected by schema
- Payment failure or insufficient USDC balance blocks the request via x402 protocol
- Malformed body or unsupported bodyType enum value causes rejection
- Target endpoint unreachable results in error response
