## 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-text-number-extractor-dacb6998 -d '<json body>'
```

Example prompt: Pull out all the numbers from this text for me: 'In Q3 2024, revenue grew by 14.7% to $2.3 billion, with operating costs at $890 million and a headcount of 4,200 employees.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call solution to extract numeric values from unstructured text without spinning up your own parsing logic. Best suited for agent pipelines that occasionally need number extraction and want to avoid per-seat SaaS subscriptions. At $0.004 per call it is cost-effective for moderate-volume use cases on the Base blockchain payment rail.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- Payment failure via x402 — 402 response with payment requirements
- Ambiguous numeric formats (e.g. written-out numbers like 'forty-two') may not be extracted
- Non-numeric content returns an empty result set

## How this service works

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