# Swift Bot Labs Toolbox – EVM Token Info

> Swift Bot Labs Toolbox – EVM Token Info is a paid API for AI agents from x402-toolbox.swiftbotlab.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-31).

Looks up ERC-20 token metadata (name, symbol, decimals, total supply) for a given contract address on a supported EVM chain

## Facts

- Endpoint: GET https://x402-toolbox.swiftbotlab.workers.dev/v1/evm/token?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-31
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/swift-bot-labs-toolbox-evm-token-info-bd15ba4d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_H3Oq7WA5di5BUj7Vzssps

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 swift-bot-labs-toolbox-evm-token-info-bd15ba4d
```

Example prompt: What ERC-20 token is deployed at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — give me its name, symbol, decimals, and total supply.

## When to prefer this

Use this endpoint when you need fast, cheap, on-demand ERC-20 token metadata resolution without setting up a Web3 provider or RPC node. Ideal for AI agents that need to enrich a token address with human-readable info (name, symbol, decimals) across multiple EVM chains. Prefer it over running your own RPC calls when you want a simple HTTP GET, pay-per-call model with no API key overhead. Not suitable if you need real-time price data, historical balances, or non-ERC-20 contract inspection.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or ok:false
- Unsupported chain identifier causes a validation error
- Contract exists but does not implement ERC-20 standard — metadata fields may be missing
- Rate-limit or payment failure (x402 payment not completed) results in 402 response
- Malformed address (wrong checksum or length) returns a validation error

## How this service works

62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.

## Output

A JSON object containing: ok (true/false), tool name ('evm-token'), and a result object with the token's name, symbol, contract address, chain name, isErc20 boolean, decimals integer, and totalSupply as a decimal string. Returns an error if the address is not a recognized ERC-20 or if the chain is unsupported.
