## 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-dns-record-diff-66feb2af -d '<json body>'
```

Example prompt: Compare these two sets of DNS records for me and tell me exactly what changed — what was added, what was removed, and whether anything is different: before had an A record pointing to 192.0.2.1 and after has an A record pointing to 192.0.2.2.

## When to prefer this

Choose this endpoint when you need a structured, programmatic diff of two DNS record sets — especially in agent workflows where you want machine-readable output (added/removed arrays, counts, changed boolean) rather than a human-readable diff. It is ideal for monitoring pipelines, post-deployment verification, and security auditing. At $0.001 USDC per call with no signup required, it is well-suited for frequent automated checks.

## Known failure modes

- Input arrays exceed 500 item limit — request rejected
- Malformed DNS record objects in before/after arrays — parsing error
- Empty or missing before/after fields — may return trivially empty diff
- Payment failure via x402 — 402 response with payment requirements
- Network timeout for large record sets approaching the 500-item limit

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object containing arrays of added and removed DNS records (each with type and value), counts of before/after/unchanged records, and a boolean 'changed' flag indicating whether any differences exist. The schema identifier 'delx/util-dns-record-diff/v1' is also returned.
