## 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 402-com-tr-token-momentum-1ded739c
```

Example prompt: What's the current momentum for the Base token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — give me the price changes across 1h, 6h, and 24h windows and tell me whether it's trending strong up, neutral, or strong down.

## When to prefer this

Use this endpoint when you need multi-window momentum context (1h, 6h, 24h) for a Base token rather than a simple 24h price snapshot. It is ideal for agents making trading decisions, alerting on trend reversals, or comparing short vs. long window momentum with a single call.

## Known failure modes

- Invalid or non-Base contract address returns an error or empty result
- Token not listed on supported DEX data sources returns no data
- Network timeout if on-chain data is slow to aggregate
- Malformed address string causes a 400-level error

## How this service works

Price change and trading volume across 1h, 6h and 24h windows for a Base token, plus a trend read (strong_up → strong_down). Lets agents gauge momentum, not just a single 24h number.

## Output

Returns price percentage changes for 1h, 6h, and 24h windows, trading volume data, and a trend label (e.g. strong_up, up, neutral, down, strong_down) for the specified Base token contract address.
