# Wave Radar — Base Chain Token Momentum Scanner

> Wave Radar — Base Chain Token Momentum Scanner is a paid API for AI agents from store.agentexchange.work, paid per call via x402, $0.09/call, status unknown (last checked 2026-09-14).

Scans Base chain DEX activity to surface early-momentum token candidates ranked by liquidity, buying flow, and traction score with risk classification.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 wave-radar-base-chain-token-momentum-scanner-d49efc85
```

Example prompt: Show me the top 5 momentum tokens on Base right now — ones with at least $10,000 in DEX liquidity, ranked by traction score and flagged if they look risky.

## When to prefer this

Choose this endpoint when you need a ready-ranked, risk-annotated shortlist of momentum tokens on Base with traction scoring baked in — rather than raw DEX feeds that require your own scoring logic. Ideal for trading agents, sniper bots, and daily watchlist generators that want an opinionated signal rather than raw data. Prefer over generic token launch feeds (like Dexscreener new launches) when you want momentum signals with liquidity filters already applied, not just recency.

## Known failure modes

- No candidates returned if no tokens meet the min_liquidity threshold at query time
- Stale or low-signal results during low-activity market periods
- limit parameter out of range (must be 1-8) may return error or default
- Payment failure via x402 if USDC balance is insufficient
- Transient 402 if x402 payment flow is not properly handled by calling agent

## How this service works

Machine-payable data APIs for AI agents across web search, on-chain reads, trading data, market judgment, and AI visibility. The canonical x402 catalog currently exposes 85 paid routes. Pay per call in USDC via x402 on Base. No API keys, no signup.

## Output

Returns a JSON object with the chain name, count of candidates found, and an array of ranked token entries each containing: symbol, contract address, classification (WATCH/REVIEW), traction_score, liquidity_usd, volume_24h_usd, risk_flags array, and a 'why' array explaining the ranking rationale. Also includes a methodology object describing the scoring approach.
