## 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-token-mentions-extractor-2571544e -d '<json body>'
```

Example prompt: Can you extract and count all the token mentions from this article text — I want to see which terms appear most frequently? Here's the text: 'Blockchain technology enables decentralized finance. Blockchain is transforming finance globally. Decentralized finance is growing rapidly.'

## When to prefer this

Choose this endpoint when you need a low-cost, per-call token mention extraction from text without standing up your own NLP infrastructure. Ideal for autonomous agents that process variable volumes of text and want pay-as-you-go pricing via x402 on Base. Best for text up to 50,000 characters where identifying or counting word/token occurrences is the primary goal.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty text input — may return empty result or error
- Malformed JSON body — 400 bad request
- Payment failure via x402 on Base — 402 response blocking processing
- Network timeout for very large text inputs near the character limit

## How this service works

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

## Output
