# Cambrian x402 EVM Tokens

> Cambrian x402 EVM Tokens is a paid API for AI agents from x402.cambrian.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a list of EVM token data for blockchain networks, served pay-per-use via the x402 micropayment protocol.

## 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 cambrian-x402-evm-tokens-de4088fa
```

Example prompt: Can you pull the list of EVM tokens available from Cambrian's x402 blockchain data API? I want to see what tokens are supported across EVM chains.

## When to prefer this

Choose this endpoint when you need a structured, pay-per-use list of EVM tokens from a blockchain-native data provider that supports the x402 micropayment protocol. Ideal for autonomous agents that need token metadata without long-term API subscriptions, or when building DeFi workflows that require on-demand token discovery across EVM-compatible chains.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Invalid or unsupported query parameters — may return empty array or 400 error
- Network connectivity issues to x402.cambrian.org — connection timeout
- Rate limiting or usage caps exceeded — may return 429 Too Many Requests
- Requested chain or token filter returns no results — empty array response

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of EVM token records, likely including token addresses, names, symbols, and chain identifiers for supported EVM networks. Each call costs $0.05 USDC via x402 micropayment.
