How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the echoed confidence value, a boolean 'within_bounds' indicating whether it falls between the supplied minimum and maximum, a 'truth_verified' flag, a 'status' of pass or fail, the operation identifier, and an evidence block containing a SHA-256 hash of the input and confirmation that no data was retained and no external calls were made.
Example use cases
Gate agentic action on confidence threshold
“Before my agent takes any irreversible action, check that its confidence score of 0.72 falls between the required minimum of 0.6 and maximum of 0.9 — I need a cryptographic receipt confirming the check passed.”
Audit trail for regulated AI decision
“I need to verify and record that the model's confidence of 0.91 is within our policy bounds of 0.85 to 0.99 — can you run a confidence check and return the SHA-256 evidence hash for our compliance log?”
Reject low-confidence classification results
“My classifier returned a confidence of 0.43 — check whether that's within the acceptable range of 0.7 to 1.0 and tell me if it passes or fails so I can decide whether to escalate to a human reviewer.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-result-confidence-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, cryptographically evidenced confirmation that a confidence score is within a defined range — especially in agentic pipelines where auditability matters. Prefer it over in-code comparisons when you need a verifiable, tamper-evident receipt of the check, or when operating under compliance requirements that demand external proof of decision thresholds. At $0.001 USDC per call with no signup, it suits high-frequency automated pipelines.
Side effects
- Missing required fields (confidence, minimum, maximum) — returns validation error
- Confidence value outside representable numeric range — may return unexpected bounds result
- Payment failure via x402 protocol — request blocked before processing
- Malformed JSON body — returns parse error
