# TraceFast Ethereum Token Metadata

> TraceFast Ethereum Token Metadata is a paid API for AI agents from mpp.tracefast.xyz, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Returns live on-chain metadata for a single ERC-20/ERC-721/ERC-1155 token contract on Ethereum mainnet, including standard, symbol, name, decimals, all-time transfer count, and distinct holder count.

## Facts

- Price: $0.005/call
- Payment: x402

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 tracefast-ethereum-token-metadata-01da806e
```

Example prompt: Look up the token standard, symbol, name, decimals, total transfer count, and distinct holder count for the Ethereum contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48.

## When to prefer this

Use this endpoint when you need quick, live token metadata for a specific Ethereum mainnet contract — especially when you need the token standard classification, symbol/name/decimals, and on-chain transfer or holder statistics in a single call. Prefer this over block explorer scraping or multicall setups when you want structured, indexed data with a predictable schema and cost.

## Known failure modes

- Invalid or malformed contract address returns an error
- Address is not a recognized token contract returns empty or null standard
- Contract has no indexed events yet returns zero counts
- Rate limiting or payment failure returns 402 or 429 status
- Address on a chain other than Ethereum mainnet (chain 1) is not supported by this endpoint

## How this service works

TraceFast live Ethereum data: one token contract — its standard as observed from its events (`erc20`, `erc721`, `erc1155`), the symbol, name and decimals it declares (verbatim, not verified), its all-time transfer count and, where indexed, its all-time distinct holder count. Path token: The token contract address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/token.md

## Output

Returns a JSON object with: the detected token standard (erc20, erc721, or erc1155), the self-reported symbol and name (verbatim from contract), decimal places (for fungible tokens), the all-time count of transfer events indexed, and where available the all-time count of distinct addresses that have held the token.
