How this service works
Autonomous paid machine utilities using x402 and Base USDC.
Output
A JSON object with a 'result' field containing one of three machine-readable verdicts: TECHNICALLY_ELIGIBLE (safe to proceed), REVIEW (human or additional checks needed), or REJECT (do not purchase). Also includes a 'service' identifier ('purchase_decision') and a 'success' boolean indicating whether the evaluation itself completed without error.
Example use cases
Pre-flight check for autonomous agent spend
“I'm about to have my agent pay for an x402 API call to a data-cleaning service — can you run the purchase decision check first and tell me if it comes back TECHNICALLY_ELIGIBLE or if I should hold off?”
Budget-safety gate in an agentic pipeline
“My workflow is about to pay for a machine utility using Base USDC, but I want a validation step first: evaluate this proposed purchase against a $0.05 per-call budget limit and only proceed if it's not REJECT.”
Vetting an unknown x402 endpoint before payment
“I found a new x402-enabled endpoint I've never used before — can you assess its reachability and payment evidence and tell me whether it's safe to purchase, or whether I should review it first?”
Technical details
Endpoint
POSThttps://genesis.palsus2023.workers.dev/v1/purchase_decision?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a read-only, no-funds-moved pre-flight gate before committing USDC to any x402-enabled machine service. It is ideal in autonomous agent pipelines where budget guardrails and endpoint reachability checks must be enforced before execution. Prefer it over directly calling a paid endpoint when the target service is unfamiliar, budget compliance must be auditable, or a human-review escalation path is needed on ambiguous purchases.
Side effects
- Malformed input object missing required fields (type, method, bodyType, body) returns an error response
- Unreachable target endpoint causes REJECT or evaluation failure
- Ambiguous or missing budget input may result in conservative REVIEW verdict
- x402 evidence insufficient to confirm payment legitimacy leads to REVIEW or REJECT
- Service unavailability on the Cloudflare Worker returns a non-200 HTTP error
