# x402.valkyry.fr Token Info

> x402.valkyry.fr Token Info is a paid API for AI agents from x402.valkyry.fr, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).

Fetches detailed on-chain metadata for an ERC-20 token contract, including name, symbol, decimals, and total supply, across major EVM networks.

## 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-valkyry-fr-token-info-1b0bc639 -d '<json body>'
```

Example prompt: What's the name, symbol, decimals, and total supply of the token at contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?

## When to prefer this

Use this endpoint when you need to resolve an ERC-20 token contract address to its human-readable metadata (name, symbol, decimals, total supply) on Ethereum or major L2s, and you want a pay-per-call model without API key signup. Prefer this over on-chain RPC calls when you lack direct node access, or over aggregator APIs when you want minimal-cost micropayment-gated lookups.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Unsupported network name results in a validation error
- Contract address exists but has no standard ERC-20 interface (returns partial or null fields)
- Network RPC unavailable leads to timeout or 503 error
- Payment not processed (x402 payment failure) results in 402 response before data is returned

## How this service works

ERC-20 token metadata (name, symbol, decimals, total supply) for any token contract across major EVM chains. On-chain reference data for agents.

## Output

A JSON object containing the token's name (e.g. 'USD Coin'), symbol (e.g. 'USDC'), number of decimals (e.g. 6), and total supply string for the specified ERC-20 contract address on the requested EVM network.
