# xx402 Base Token Watchlist Risk Digest

> xx402 Base Token Watchlist Risk Digest is a paid API for AI agents from x402.xx402.icu, paid per call via x402, $0.01/call, status down (last checked 2026-10-24).

Discovers, ranks, and performs multi-layer risk analysis on Base chain tokens, returning a prioritized watchlist with trade-safety checks, threat flags, and DeFi risk breakdowns.

## 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-token-watchlist-risk-digest-ae67d973
```

Example prompt: Search Base chain tokens matching 'aerodrome,virtual,base', rank the top 5 candidates, run deep contract probes on 2 of them, and give me a full risk breakdown and watchlist with trade-safety checks using the last 100 blocks.

## When to prefer this

Use this endpoint when an autonomous agent or risk tool needs a one-call, multi-layer Base chain token risk digest — combining Dexscreener discovery, contract-control probing, trade-safety flow checks, and holder subchecks into a single ranked output. Prefer this over generic token price APIs when you need threat classification, honeypot detection signals, and actionable watchlist/avoid queues for DeFi trading or risk management on Base.

## Known failure modes

- No tokens found matching the query terms — try broadening the search query or lowering liquidity/volume thresholds
- Payment not processed (x402 protocol failure) — agent must handle 402 response and retry with valid USDC payment
- Rate limiting or upstream Dexscreener API unavailability causing empty discovery results
- Invalid parameter values (e.g. limit out of range 2-8, window_blocks below 100) return validation errors
- Slow on-chain RPC responses may cause incomplete trade-safety packet data for some candidates

## 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

Returns a JSON object containing a ranked list of Base chain token candidates with trade-safety packets, risk breakdowns, flagged tokens, threat type counts, watchlist/review/avoid queues, a bot execution plan, a priority queue, discovery radar data, source status, and a disclaimer. Keys include: summary, ranked_tokens, trade_safety_packets, flagged_tokens, risk_breakdown, watchlist, review_queue, avoid_queue, priority_queue, threat_type_counts, bot_execution_plan, discovery_radar, and others.
