# Delx Commerce — Agent Result Envelope Check

> Delx Commerce — Agent Result Envelope 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 that an agent's result object conforms to a standard delivery envelope schema, confirming presence of required fields and data integrity without retaining input.

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-envelope-check-1d3093ba -d '<json body>'
```

Example prompt: Can you check whether this result object I'm about to submit passes the Delx agent result envelope check — I need to confirm it has all required fields and a data or error value before I finalize delivery?

## When to prefer this

Use this endpoint when you need a lightweight, privacy-preserving, verifiable check that an agent result object conforms to the standard delivery envelope schema before submission or downstream processing. Prefer it over manual schema checks when you need a cryptographic evidence record (SHA-256) proving the check was performed without data retention, or when operating within a pay-per-result agent commerce workflow on Base or Solana via x402.

## Known failure modes

- Input object exceeds 128 properties (maxProperties limit) — request rejected
- Malformed JSON body — parsing error returned
- Result object missing entirely — validation cannot proceed
- Payment not included or insufficient USDC — 402 response before processing

## 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 'valid' boolean, a 'missing_fields' array listing any absent required fields, a 'has_data_or_error' boolean confirming payload content, an overall 'status' (pass/fail), and an evidence block containing the input SHA-256 hash, a 'retained: false' flag confirming no data is stored, and an external_calls count of 0.
