## 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 one-engine-t9-phone-number-extractor-82981f7b -d '<json body>'
```

Example prompt: Can you pull out all the T9-encoded phone numbers from this text? Here it is: 'Call us at 484-968-3626 or reach support at 227-867-5309.'

## When to prefer this

Use this endpoint when you need to extract T9-encoded or numeric phone number sequences from unstructured text at low cost ($0.018 per call) on the Base blockchain via x402 micropayments. Prefer this over general-purpose NLP or regex solutions when working within an autonomous agent pipeline that already uses x402 payment rails.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- No T9 numbers found — empty result set returned
- Malformed JSON input — 400 error
- Payment not included or insufficient USDC — 402 payment required
- Ambiguous numeric sequences that may not be T9-encoded returned as false positives

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output
