## 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-extraction-t7-4bfd107b -d '<json body>'
```

Example prompt: Scan this article text for any cryptocurrency or token mentions and tell me which tokens are referenced: 'Ethereum and Solana dominated last week's trading volume, while Bitcoin remained flat and a new Uniswap proposal stirred debate...'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call extraction of cryptocurrency or financial token mentions from arbitrary text. It is ideal for agents processing news articles, social media posts, research documents, or user-generated content where identifying referenced tokens is the primary goal. At $0.0065 USDC per call on Base via x402, it is well-suited for high-frequency autonomous agent workflows that require cost-efficient, per-request billing without subscription overhead.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Empty or whitespace-only text returns no mentions
- Text with no token references returns an empty mentions list
- Payment failure via x402 results in 402 response and no extraction
- Ambiguous token names (common words) may result in false positives or missed mentions

## How this service works

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

## Output
