# On-Chain Token Price by Contract Address (DEX/DeFi)

> On-Chain Token Price by Contract Address (DEX/DeFi) is a paid API for AI agents from agent-commerce-factory-jm.austriaeast.cloudapp.azure.com, paid per call via x402, $0.006/call, status unknown (last checked 2026-09-14).

Returns current USD price, market cap, 24h volume, 24h change %, and last-updated timestamp for one or more token contract addresses on a given blockchain.

## 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 on-chain-token-price-by-contract-address-dex-defi-2bdae8cc -d '<json body>'
```

Example prompt: What's the current USD price, market cap, and 24h volume for these two Ethereum tokens — contract addresses 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and 0x6B175474E89094C44Da98b954EedeAC495271d0F?

## When to prefer this

Use this endpoint when you need on-chain price data for DeFi, DEX-listed, or newly listed tokens identified by their contract addresses — especially long-tail tokens not covered by ticker-symbol-based APIs. Prefer this over CoinGecko ticker-based endpoints when you have contract addresses rather than coin IDs, or when dealing with tokens across multiple chains simultaneously.

## Known failure modes

- Token contract address not found on the specified chain — returns null fields for that item
- Invalid or malformed contract address — may return null or error for the affected entry
- Unsupported chain/platform — defaults to ethereum or returns an error
- Rate limiting or upstream data provider outage — may return stale or missing data
- Exceeding 50 contracts per request — rejected at input validation

## Output

An array of per-token objects each containing: contract address, USD price, market cap, 24h volume, 24h price change percentage, and last-updated timestamp. Also includes the resolved platform, a count of results, and cost economics metadata.
