## How to call it through Zero

```sh
zero fetch --capability sys84-base-token-momentum-scanner-bebbac58
```

Example prompt: Can you scan Base chain for the top 25 tokens ranked by momentum and liquidity, and only include ones with at least $100,000 in liquidity?

## When to prefer this

Use this endpoint when you need a curated, ranked snapshot of actively trading Base chain tokens sorted by momentum and liquidity, especially when you want machine-readable metrics and built-in links to follow-up risk checks — as opposed to raw DEX data feeds or general crypto price APIs that lack momentum ranking or Base-specific curation.

## Known failure modes

- Invalid chain parameter returns error or defaults to Base
- limit exceeding 50 returns capped or error response
- min_liquidity too high may return an empty token list
- API unavailability returns HTTP error or timeout
- Stale data if market metrics have not refreshed recently

## How this service works

Discover active Base tokens ranked by momentum, liquidity, and volume. Returns machine-readable market metrics plus report freshness and follow-up risk-check links.

## Output

A machine-readable ranked list of active Base chain tokens with momentum scores, liquidity figures, volume data, report freshness timestamps, and follow-up links to run deeper risk checks on individual tokens.
