## 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 crypto-coin-profile-e6dc8d8a
```

Example prompt: Can you pull up the full profile for Ethereum — I want to see its description, website, GitHub, contract addresses across chains, current market cap, price, and how it's changed over the last 24h, 7 days, and 30 days?

## When to prefer this

Choose this endpoint when you need a rich, all-in-one profile of a single cryptocurrency including social links, contract addresses across multiple chains, full price history changes, and supply details — rather than just a price ticker. It's ideal for due diligence, research reports, or enriching token data in an agent workflow. Prefer the sibling 'Top Crypto by Market Cap' endpoint when you need a ranked list of many coins instead of deep data on one specific coin.

## Known failure modes

- Unknown or misspelled coin symbol/ID returns a 404 or empty result
- Ambiguous symbol (e.g. 'USDT' matching multiple tokens) may return unexpected coin
- CoinGecko rate limits or downtime cause upstream errors
- Very new or obscure tokens may have incomplete metadata (missing description, links, or price history)
- Network timeout from the hosted Render.com instance under load

## How this service works

Full profile of a coin by symbol or CoinGecko id: description, website, X/Twitter, GitHub, categories, contract addresses per chain, price, market cap, FDV, volume, 24h/7d/30d/1y change, all-time high/low and supply. Use for token research or due diligence.

## Output

A structured JSON object containing the coin's full name, description, official website, X/Twitter and GitHub URLs, category tags, contract addresses indexed by blockchain, current USD price, market cap, fully diluted valuation, 24-hour trading volume, percentage price changes over 24h/7d/30d/1y, all-time high and low prices with dates, and circulating/total supply figures.
