## 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 xx402-base-promoted-token-risk-radar-0fdd8580
```

Example prompt: Can you screen the top 6 promoted Base chain tokens for risk right now, probing the top 2 contracts for control issues, and only include tokens with at least $5,000 liquidity and $100 in 24h volume — sort them into buy, watchlist, and avoid buckets?

## When to prefer this

Choose this endpoint when an autonomous agent or risk tool needs real-time, pre-filtered, risk-tiered data on promoted Base chain tokens specifically — including contract control signals and DEX liquidity gates — rather than generic token price feeds or unfiltered on-chain data streams.

## Known failure modes

- No promoted token campaign rows found — falls back to fallback_query search terms
- Token liquidity or volume below thresholds causes empty result queues
- Deep contract probes may time out or return partial data for fast-moving tokens
- Payment not accepted if x402 USDC balance is insufficient
- limit or deep_limit out of valid range returns schema validation error

## How this service works

Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.

## Output

A JSON object containing a summary, buy/watchlist/avoid queues, per-token risk breakdowns, contract control probe results, liquidity and volume data, bucket counts, source status, and a disclaimer — structured for direct consumption by autonomous agents making DeFi trading decisions.
