## 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 gate402-momentum-order-flow-signal-7f716611 -d '<json body>'
```

Example prompt: Before I trade, check the momentum and order-flow signal for the Base token at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — is it RISING or FALLING, is there accumulation or distribution pressure, and does it pass the honeypot check?

## When to prefer this

Use this endpoint when a trading agent needs a fast, factual, multi-timeframe momentum read on a specific Base token before executing a swap, screening new launches, or deciding whether to enter/exit a position. It uniquely combines price trend classification, order-flow signal (accumulation vs distribution), and a live honeypot safety gate in a single call. Prefer this over raw DEX price endpoints when you need directional and safety context, not just a spot price.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or null signal
- Token has no liquidity or DEX pool on Base — insufficient data to classify
- Honeypot check service temporarily unavailable — honeypot field may be null or error
- Very new token with insufficient price history — some timeframe signals may be absent
- Rate limiting or payment failure (x402) results in 402 response

## How this service works

Factual momentum + order-flow signal for a Base token: price trend (5m-24h), buy/sell pressure, and volume trend, classified as RISING/FALLING/FLAT + ACCUMULATION/DISTRIBUTION and gated by a live honeypot check. For trading agents — the read, not a prediction.

## Output

Returns a structured signal object including: price trend direction (RISING/FALLING/FLAT) across multiple timeframes (5m to 24h), buy/sell pressure ratio, volume trend direction, an order-flow classification (ACCUMULATION/DISTRIBUTION), and a live honeypot check result indicating whether the token contract is safe to trade. This is a factual read of current market state, not a price prediction.
