Agent Result Provenance Check
x402
Agent Result Provenance Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Validates the provenance of an agent result by checking its source, observation time, and collection method, returning acceptance or rejection status with normalized evidence and mismatch reasons.

How this service works
Agent Result Provenance Check: Agent Result Provenance Check checks result provenance for source, observed time, and method from bounded caller-supplied values without an external provider. Call Agent Result Provenance Check before paying for or accepting an x402 or agent delivery assembled from caller-supplied challenge and result metadata. Returns contract-specific checks, normalized evidence, mismatch reasons, and an explicit acceptance or rejection status for Agent Result Provenance Check a…
Output
Returns a structured response with contract-specific validation checks, normalized evidence derived from the provenance fields, a list of mismatch reasons if any discrepancies are found, and an explicit acceptance or rejection status indicating whether the agent result should be trusted or rejected.
Example use cases
Pre-payment provenance gate
“I just got an agent result back for my x402 task and I want to pay out, but first check the provenance object — source, observed time, and method — and tell me if there are any mismatches or if I should accept it.”
Automated delivery audit
“Run a provenance check on this agent delivery result before I accept it: verify the source, when it was observed, and how it was collected, and flag anything suspicious.”
Rejecting a stale or mismatched result
“I have a result from an agent that looks like it might be using outdated or spoofed provenance data — can you check its source and observed time metadata and let me know if it passes or gets rejected?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/agent-result-provenance-checkWhen to prefer
Choose this endpoint when you need to gate acceptance of an agent-delivered result on verifiable provenance before settling an x402 payment or triggering a downstream workflow. It is purpose-built for agentic result validation where source, observation time, and method must be checked against bounded caller-supplied values without external lookups, making it lightweight and fast. Prefer this over manual inspection when operating in automated agent pipelines where trust decisions must be auditable and normalized.
Side effects
- Provenance object exceeds 128 properties — rejected with validation error
- Missing or malformed observed time field — may result in rejection with mismatch reason
- Unknown or unsupported collection method — flagged in mismatch reasons
- Empty provenance object — may produce rejection with insufficient evidence
- Payment not included or underpaid — x402 payment required error
