# ArgonautWorks Trending Base Tokens and Token Lookup API

> ArgonautWorks Trending Base Tokens and Token Lookup API is a paid API for AI agents from argonaut-base-token-momentum-pulse.vercel.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Looks up and ranks Base network tokens by USDC swap volume and buy/sell activity derived from a sealed 300-block onchain window, returning trending candidates or matching a query string.

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 argonautworks-trending-base-tokens-and-token-lookup-api-d3ba4f53 -d '<json body>'
```

Example prompt: Search for the top 5 trending tokens on Base matching the query 'uni', ranked by USDC swap volume from the last 300 blocks of onchain activity.

## When to prefer this

Choose this endpoint when you need real-time, onchain-validated token momentum data on the Base network specifically — particularly when you want USDC swap volume and buy/sell activity ranked from actual DEX logs rather than aggregated off-chain price feeds. It is especially useful for token discovery by prefix or partial name when you need to resolve a symbol to an address alongside fresh trading metrics.

## Known failure modes

- Query string matches no tokens — empty candidates array returned
- Limit parameter out of bounds — may return error or default result count
- Network or Vercel cold-start latency causing slow response
- Stale data if the 300-block window has not refreshed
- Malformed POST body causing 400-level error
- Token address provided does not exist on Base — no match returned

## How this service works

Trending Base token data ranked by exact USDC swap volume and buy/sell activity, plus a bounded active-token lookup, derived from a sealed 300-block window of validated direct onchain logs.

## Output

Returns a list of candidate tokens ranked by USDC swap volume, each including the token name, symbol, and address, the match method used (e.g. prefix), atomic USDC volume, participating liquidity pools, and the count of unique swap transactions — all derived from a sealed 300-block window of validated onchain logs.
