# Delx Commerce — Agent Delivery Partial Result Check

> Delx Commerce — Agent Delivery Partial Result 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 partial delivery of items meets a minimum coverage fraction threshold, returning an acceptance decision and coverage metrics.

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-delivery-partial-result-check-041735f9 -d '<json body>'
```

Example prompt: Check if delivering 95 out of 100 expected items is acceptable given a minimum coverage fraction of 0.90 — I need to know if it passes and how many items are missing.

## When to prefer this

Choose this endpoint when an AI agent needs a cryptographically evidenced, pay-per-result check of whether a partial delivery satisfies a minimum coverage threshold — especially in agent-to-agent commerce scenarios where verifiable, tamper-evident delivery confirmation matters. Prefer this over custom logic when you need an immutable SHA-256 input hash and a no-data-retention guarantee baked into the response, or when settling pay-per-result contracts on Base or Solana via x402.

## Known failure modes

- Missing required fields (expected_items, delivered_items, or minimum_fraction) returns a validation error
- Non-integer values for expected_items or delivered_items may cause schema rejection
- minimum_fraction outside 0–1 range may produce unexpected behavior
- Payment failure via x402 protocol results in 402 response before computation occurs
- expected_items of 0 may cause division-by-zero or undefined coverage_fraction

## 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: accepted (boolean indicating pass/fail), missing_items (integer count of items not delivered), coverage_fraction (decimal ratio of delivered to expected), a status field ('pass' or 'fail'), and an evidence block including a SHA-256 hash of the input, a flag confirming no data was retained, and a count of external calls made (always 0).
