# Delx Commerce — Agent Result Completeness Check

> Delx Commerce — Agent Result Completeness 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 an agent's result object contains all required fields/paths, returning a pass/fail verdict with a list of any missing paths and a cryptographic evidence hash.

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-completeness-check-54a47c78 -d '<json body>'
```

Example prompt: Check whether this result object I just got back from my agent is complete — the required paths are ['user.name', 'user.email', 'order.items', 'order.total'] — and tell me if anything is missing.

## When to prefer this

Use this endpoint when you need a lightweight, cryptographically verifiable, stateless check that a structured agent result object contains all required fields before delivery, payment, or handoff. It is ideal for agentic pipelines where you need an auditable receipt (SHA-256 hash) proving what was checked, without storing any data. Prefer this over custom validation code when you want a pay-per-call, no-signup, chain-verifiable completeness assertion.

## Known failure modes

- Malformed result object (exceeds 128 properties) — request rejected
- required_paths array exceeds 256 items — request rejected
- Individual path string exceeds 8192 characters — validation error
- Missing or malformed POST body — 400 error
- Payment failure or insufficient USDC balance — 402 Payment Required
- Path syntax errors in required_paths may cause unexpected miss-matches

## 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: a boolean 'complete' flag, an array 'missing_paths' listing any required paths absent from the result, a 'status' of 'pass' or 'fail', and an 'evidence' block containing the SHA-256 hash of the input (for verifiability), a 'retained: false' flag confirming no data storage, and an external_calls count of 0 confirming fully local processing.
