## 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-t8-0d8ce84c -d '<json body>'
```

Example prompt: Scan this article for any cryptocurrency or token mentions: 'Bitcoin surged today as Ethereum holders moved liquidity into Solana and Base-native tokens like BRETT showed strong volume.'

## When to prefer this

Choose this endpoint when you need to quickly and cheaply extract token or cryptocurrency mentions from a text passage without running a full NLP pipeline. At $0.01 per call it is cost-effective for high-volume document scanning. Prefer this over general NLP APIs when your use case is specifically focused on crypto/token entity extraction in the Base/x402 ecosystem.

## Known failure modes

- Text exceeds 50,000 character limit — request will be rejected or truncated
- Empty or whitespace-only text input returns no mentions
- Text with no recognizable token references returns an empty mentions list
- Ambiguous abbreviations may produce false positive or missed token matches
- Network or payment failure via x402 returns a 402 or 5xx error

## How this service works

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

## Output
