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 one-engine-text-number-extractor-7df0a62b -d '<json body>'
```

Example prompt: Can you extract all the numbers from this text for me? Here it is: 'The shipment of 42 units arrived on March 3rd at 09:15, weighing 1,200 kg with an invoice total of $5,849.99.'

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost, pay-per-call solution to extract numeric values from unstructured text without standing up your own parsing logic. It is ideal for autonomous agent pipelines that process documents, logs, invoices, or reports and need clean numeric data quickly. At $0.0015 USDC per call on Base via x402, it suits high-frequency, cost-sensitive workflows.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error
- No numbers present in text — returns empty result
- Payment failure via x402 — 402 response, call not processed
- Ambiguous number formats (e.g. mixed locale decimals) may be inconsistently parsed

## How this service works

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

## Output
