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-ef0c4dcc -d '<json body>'
```

Example prompt: Can you extract all the numbers from this text for me: 'The shipment weighed 34.5 kg, arrived on the 12th, and cost $1,200 with a 15% discount applied to 3 items'?

## 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. At $0.001 USDC per call, it is ideal for high-volume agent workflows where pulling numbers from text is a recurring subtask. Prefer this over general-purpose LLM calls when you want deterministic, structured numeric extraction at minimal cost.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected
- Empty or missing 'text' field — validation error returned
- No numbers present in text — likely returns empty result set
- Malformed JSON request body — parse error
- Payment failure via x402 — 402 response before processing begins

## How this service works

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