# Delx Commerce — Agent Result Confidence Check

> Delx Commerce — Agent Result Confidence Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Validates whether a given confidence score falls within specified minimum and maximum bounds, returning a verifiable pass/fail result with cryptographic evidence.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-agent-result-confidence-check-335872b4 -d '<json body>'
```

Example prompt: Check whether a confidence score of 0.8 is within bounds — minimum 0.5 and maximum 0.95 — and give me a verifiable result I can use as proof.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
