# Crosschain Radar — Multi-Chain Token Attention Scanner

> Crosschain Radar — Multi-Chain Token Attention 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).

Returns a ranked list of cross-chain token candidates gaining attention across Solana, Base, Ethereum, and Robinhood, with liquidity, volume, traction scores, and classification labels.

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 crosschain-radar-multi-chain-token-attention-scanner-fa2ec1f8
```

Example prompt: Give me the top 12 cross-chain token candidates right now across Solana and Base, filtering to at least $25,000 in DEX liquidity — I want traction scores, 24h volume, and classification labels so I can decide what needs diligence.

## When to prefer this

Choose this endpoint when you need a ranked, multi-chain view of tokens gaining attention with liquidity and volume context — especially when you want cross-chain comparison rather than single-chain feeds. Prefer this over single-chain token launch feeds (like Dexscreener new launches) when you care about relative attention across chains rather than raw recency. Best for pre-trade screening, watchlist building, and chain-level momentum analysis. Not suitable for historical data queries or detailed on-chain contract reads.

## Known failure modes

- Invalid chain name in 'chains' parameter returns error or empty results
- Limit value outside 1-16 range may be clamped or rejected
- min_liquidity set too high may return zero candidates
- Payment not received (402) — call not fulfilled without valid x402 USDC payment on Base
- Transient upstream data lag may cause stale traction scores
- Safety coverage may be 'unavailable' for some tokens, reducing signal quality

## 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

A JSON object containing: an array of ranked token candidates (each with rank, chain, liquidity_usd, classification label, traction_score, volume_24h_usd, and safety_coverage status), the attention_leader chain, and a chain_distribution array showing each chain's candidate count and boost share percentage. Also includes a methodology object explaining the ranking logic.
