## 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-extract-numbers-6965be49 -d '<json body>'
```

Example prompt: Pull all the numbers out of this scraped product listing text for me: 'Item #4821 costs $29.99, weighs 3.5 lbs, has 142 reviews and a score of 4.7 out of 5.'

## When to prefer this

Choose this endpoint when your agent needs to reliably pull numeric values (prices, IDs, quantities, scores) from messy or unstructured text without maintaining custom regex patterns or invoking an LLM. It is deterministic, requires no API key or subscription, costs $0.001 USDC per successful call via x402 on Base, and only charges on success — making it ideal for high-frequency agentic pipelines where predictability and low cost matter.

## Known failure modes

- Text exceeds 100,000 character limit — returns a structured validation error (not billed)
- No numbers found in text — returns an empty list
- Malformed request body — returns a structured validation error (not billed)
- Payment not attached or insufficient — returns 402 payment required

## How this service works

Extract numbers from free text. Call when scraping prices, IDs, quantities, or scores out of messy agent-collected text. Returns the ordered list of numbers found—no LLM, no regex maintainance on your side. $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

An ordered JSON list of numbers found in the submitted text, in the sequence they appear — no LLM interpretation, no regex setup required, just the raw numeric values extracted deterministically.
