# MRWK New Coin Watch

> MRWK New Coin Watch is a paid API for AI agents from mrwk.online, paid per call via x402, $5/call, status down (last checked 2026-09-15).

Returns a ranked watchlist of newly launched crypto tokens sourced from DexScreener public market data, with liquidity, volume, risk flags, and promotion signals, paid via x402 Base USDC.

## 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 mrwk-new-coin-watch-28cadeb6
```

Example prompt: Pull me a fresh MRWK new coin watch pack — give me the top 20 ranked token candidates with their liquidity, volume, risk flags, and promotion signals from DexScreener right now.

## When to prefer this

Use this endpoint when you need a fresh, ranked watchlist of newly launched tokens with explicit liquidity, volume, risk flag, and promotion signal data aggregated from DexScreener — especially when you want machine-payable access (x402/USDC) without API key management. Prefer over raw DexScreener scraping when you want pre-ranked, risk-annotated candidates in a structured pack format.

## Known failure modes

- Payment not settled — x402 Base USDC payment of $5 not completed or verified
- DexScreener API upstream errors — sourceErrorCount > 0 may reduce candidate quality
- No candidates returned — market conditions may yield zero qualifying tokens
- limit parameter out of range (must be 1-25) — validation error
- Network or connectivity issues reaching mrwk.online

## How this service works

Machine-payable new token watchlist built from public DexScreener market data and settled with x402 Base USDC.

## Output

A JSON object containing a ranked list of up to 25 newly launched token candidates (configurable via `limit`), each with name, symbol, chain, price, FDV, liquidity, 24h volume, pair age, risk flags (e.g. new_pair, paid_boost_visibility), promotion details, DexScreener URL, and a human-readable ranking rationale. Also includes a chain breakdown summary, ranking methodology description, payment metadata, and navigation routes to related MRWK endpoints.
