## How to call it through Zero

```sh
zero fetch --capability ozmium-buy-sell-signal-feed-46da8463
```

Example prompt: What are Ozmium's current buy/sell signals for ETH — give me the bias, sentiment score, and conviction level?

## When to prefer this

Use this endpoint when you need a quick directional bias signal (buy/sell/neutral) with quantified sentiment and conviction for a crypto asset, particularly on Base mainnet context. Best suited for agents augmenting DeFi trading workflows or cross-referencing with news and on-chain data. Note: this is an experimental, unproven signal feed with no established out-of-sample edge — always corroborate before acting.

## Known failure modes

- Symbol not found or unsupported: empty or null signals object returned
- Rate limit or payment failure: 402 Payment Required if USDC micropayment not fulfilled
- Malformed query parameter: invalid symbols string may return empty results
- Service unavailable: 5xx error if the experimental API is down or under maintenance
- No signals available: signals may be sparse or absent for low-liquidity assets

## How this service works

EXPERIMENTAL / WIP- an early, unproven BUY/SELL signal feed (no established out-of-sample edge, not advice); corroborate with news + cross-asset context before acting. Full details: GET /v1.

## Output

Returns a JSON object containing per-symbol signal data including: bias (e.g. BUY/SELL/NEUTRAL string), sentiment (numeric score), and conviction (numeric score), along with the network context.
