## 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 batch-token-prices-by-coingecko-id-or-chain-address-398805f7 -d '<json body>'
```

Example prompt: What are the current prices for Bitcoin, Ethereum, and USDC — can you look them up using their CoinGecko IDs coingecko:bitcoin, coingecko:ethereum, and coingecko:usd-coin all at once?

## When to prefer this

Choose this endpoint when you need prices for multiple tokens simultaneously and want to minimize round-trips — it batches up to 25 tokens in one paid call. Prefer it over single-token lookups when building portfolio trackers, DeFi dashboards, or arbitrage bots that need current prices across several assets. Supports both CoinGecko IDs (coingecko:bitcoin) and on-chain contract addresses (chain:0x...) making it flexible for both well-known coins and long-tail EVM tokens.

## Known failure modes

- Exceeding 25 tokens in one request returns a validation error
- Unknown or misspelled CoinGecko IDs return null or error for that token
- Invalid chain:address format causes parse errors
- Unsupported chain prefix for chain:address lookups returns no data
- Payment failure (x402) blocks the request entirely
- Tokens with very low liquidity may return stale or missing prices
