## 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 starchild-relay-lunarcrush-coins-list-effa4f34 -d '<json body>'
```

Example prompt: Pull me a list of up to 50 cryptocurrencies from LunarCrush with their social sentiment data — I want to see which coins are being talked about the most right now.

## When to prefer this

Use this endpoint when you need a structured directory of cryptocurrencies with LunarCrush social sentiment signals, especially when you want to avoid direct LunarCrush API setup and prefer a single x402 micropayment interface. Ideal when building crypto dashboards or sentiment-driven trading screens that need a full coin universe.

## Known failure modes

- 402 Payment Required — no valid X-PAYMENT header provided; must include a signed micropayment for $0.00001 USDC
- 400 Bad Request — invalid limit parameter type or value
- 504 Gateway Timeout — upstream LunarCrush API unavailable
- 429 Too Many Requests — rate limit exceeded on upstream provider
- Empty result set if LunarCrush returns no coins matching the query

## How this service works

All-in-one reputable data source for AI agents and developers. Crypto spot/OHLC, derivatives funding rates, open interest, liquidations, forex, commodities, indices, social sentiment, DeFi protocols, and more — 17+ upstream data sources behind a single x402 paywall.

Usage: Send requests to any proxied path (e.g. GET /coingecko/api/v3/...). Unauthenticated requests receive a 402 challenge with payment instructions. Include X-PAYMENT header with a valid signature to access data.

## Output

A list of cryptocurrency coins tracked by LunarCrush, including coin identifiers, symbols, and associated social sentiment and market metrics, limited to the requested number of results.
