## 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 alchemy-token-prices-by-contract-address-55b1f3d3 -d '<json body>'
```

Example prompt: What's the current price of the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on eth-mainnet?

## When to prefer this

Use this endpoint when you have a specific ERC-20 token contract address and need its current price — especially for newer, obscure, or unlisted tokens that may not appear in name-based lookups. Prefer this over name-based price endpoints when you need precise on-chain contract-level price resolution across multiple EVM networks including eth-mainnet and base-mainnet.

## Known failure modes

- Invalid or unrecognized contract address returns empty or null price data
- Unsupported network slug causes a 400 or error response
- Contract address exists but token has no price feed — returns missing or zero price
- Malformed addresses array causes validation error
- Rate limiting or payment failure returns 402 or 429
- Network slug mismatch between top-level and per-address fields causes inconsistent results

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

Returns a JSON object mapping each queried contract address to its current price data, including token valuation information sourced from Alchemy's price feeds for the specified network.
