# x402 DeFi Intel – Token Resolve

> x402 DeFi Intel – Token Resolve is a paid API for AI agents from cryptodefidataintel-production.up.railway.app, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Resolves a token name or symbol query to cross-chain contract addresses and metadata across multiple blockchains

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-defi-intel-token-resolve-d49c2dd9
```

Example prompt: Can you resolve the token 'USD Coin' or 'USDC' and give me its contract addresses across all supported chains — I want to see where it's deployed on Ethereum, Base, and other networks?

## When to prefer this

Use this endpoint when you need to resolve a human-readable token name or ticker symbol to its on-chain contract addresses across multiple chains. Ideal for pre-swap, pre-bridge, or pre-approval workflows where you need the canonical contract address for a token on a specific network before executing further DeFi operations.

## Known failure modes

- Token not found: empty data array with low confidence score
- Ambiguous query returns multiple candidates requiring disambiguation
- CoinGecko upstream timeout causing delayed or failed response
- Missing required 'query' parameter returns 400 validation error
- Rate limit exceeded if payment not settled via x402

## How this service works

Crypto-agent toolkit: cross-chain DeFi intelligence + execution helpers + retrieval for agents. 16 endpoints: funding, open interest, long/short, token-safety, yield, prices, gas, tx-simulate, approval-check, bridge-quote, governance-search, lending, liquidations, protocol-search, swap-quote, token-resolve. Pay-per-call via x402.

## Output

Returns an array of matched tokens with their name, symbol, and per-chain contract addresses; a signal string (e.g. 'resolved'), a human-readable insight summary (e.g. 'USDC -> contracts on 12 chain(s)'), data source attribution (CoinGecko), and a confidence score between 0 and 1.
