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 domain-normalize-api-f3c441f8 -d '<json body>'
```

Example prompt: Can you normalize the domain 'https://www.Example.COM/some/path' down to its canonical form so I can use it consistently in my code?

## When to prefer this

Use this endpoint when you need a cheap ($0.01 USDC), reliable, deterministic way to canonicalize domain strings within a coding agent or data pipeline — particularly when operating in an x402/AgentCash micropayment environment. Prefer this over custom regex normalization when consistency and correctness of edge cases matter.

## Known failure modes

- Missing or empty 'domain' field returns an error
- Malformed input that cannot be parsed as a domain may return an error or unexpected normalization
- Network timeout on the Cloudflare Worker edge
- Invalid JSON body returns a parse error

## How this service works

Free need-to-tool routing plus pay-per-call npm docs and TypeScript API signatures, npm breaking-change diffs, JavaScript-rendered browser snapshots and deterministic coding-agent checks via AgentCash/x402.

## Output

Returns a JSON object with a 'data' field containing the normalized domain string (e.g. 'example.com') and a 'meta' field indicating the engine used ('domain-normalize'). The domain is stripped of protocol, www prefix, paths, and casing inconsistencies.
