## 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-phone-digits-normalizer-2a92e745 -d '<json body>'
```

Example prompt: Strip the formatting from this phone number and give me just the digits: +1 (415) 555-0192.

## When to prefer this

Choose this endpoint when you need a lightweight, deterministic, pay-per-call phone normalization step with no API key or subscription overhead — especially useful in agent pipelines that write to CRMs, deduplicate contact records, or preflight SMS gateway calls. Prefer it over regex-in-code when you want a consistent, hosted utility that handles edge cases without maintaining your own parsing logic.

## Known failure modes

- Empty or missing phone field returns a structured validation error (not billed)
- Input with zero digit characters returns an empty string or validation error
- Network timeout or gateway error returns a non-200 HTTP response
- Malformed JSON request body returns a structured validation error (not billed)

## How this service works

Normalize phone to digits. Use before SMS gateways, CRM writes, or dedupe on contact fields. Returns digits-only phone text (formatting stripped). $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

## Output

A JSON object containing the digits-only version of the submitted phone string, with all non-numeric characters removed. No formatting, dashes, spaces, parentheses, or country-code symbols are preserved in the output.
