> x402 tools – Token Price (Symbol/CoinGecko ID) is a paid API for AI agents from x402-tools-production-2755.up.railway.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

## 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 x402-tools-token-price-symbol-coingecko-id-62e00641
```

Example prompt: Can you pull the current prices, 24h and 7d changes, market caps, and volume for BTC, ETH, SOL, and AVAX — and also include the 7-day sparkline so I can see the trend?

## When to prefer this

Prefer this endpoint when you need to price a portfolio or watchlist of well-known tokens by ticker symbol or CoinGecko ID, especially when you want rich metadata (ATH/ATL distance, FDV, supply, multi-period changes) in a single call. It is the right choice for batch pricing of up to 50 symbols or 250 CoinGecko IDs. If you need to price long-tail or newly listed tokens by contract address that may not have a CoinGecko listing, use the contract-address pricing sibling endpoint instead.

## Known failure modes

- Symbol not found or ambiguous ticker resolves to wrong coin — no result returned, no charge
- CoinGecko ID misspelled or invalid — token silently omitted from response
- Exceeding 50 symbols or 250 CoinGecko IDs — request may be truncated or rejected
- Upstream CoinGecko rate limit or outage — may return stale or empty data
- Quote currency not supported — defaults to USD or returns error

## How this service works

Use to price a crypto portfolio or watchlist in one call. Market data for up to 50 symbols or 250 CoinGecko ids: price, 1h/24h/7d/30d change, 24h high/low, volume, market cap, rank, FDV, supply, and distance from all-time high/low; optional 7-day sparkline. One flat price per call; not charged if nothing is found.

## Output

Returns a list of market data objects, one per requested token, each containing: current price in the requested quote currency, percentage changes over 1h/24h/7d/30d, 24h high and low, 24h trading volume, market capitalization, market cap rank, fully diluted valuation, circulating and total supply, distance from all-time high and all-time low, and optionally a 7-day array of hourly prices (sparkline). If a single symbol or id is queried, returns a single object instead of a list. Nothing is returned (and the call is not charged) if no matching tokens are found.
