# Delx Control Coverage Checker

> Delx Control Coverage Checker is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-02).

Computes what percentage of required control fields are implemented, returning missing fields and a coverage score

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-control-coverage-checker-f6101833 -d '<json body>'
```

Example prompt: Check which required controls are missing from my implementation — my required controls are ['auth','approval','logging'] and I've implemented ['auth','logging'] so far.

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.003 USDC) programmatic check of control implementation completeness — especially in agent pipelines that need to gate on coverage thresholds before proceeding. Ideal when you have explicit lists of required vs. implemented controls and want a machine-readable coverage score with gap analysis. Prefer over manual diffing when automating compliance checks across multiple agent workflows.

## Known failure modes

- Missing or malformed 'required' or 'implemented' arrays returns a validation error
- Empty 'required' array may result in undefined coverage percentage
- Payment failure via x402 prevents endpoint access
- Non-array values for required/implemented fields cause schema rejection

## 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 schema identifier 'delx/util-control-coverage/v1', the list of missing required fields, the total required count, the number implemented, and the coverage percentage (0–100) as a decimal.
