Swift Bot Labs Toolbox – EVM Token Info
x402
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

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.
Example use cases
DeFi token discovery for unknown address
“I just found this contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — can you tell me what token it is, its symbol, how many decimals it has, and its total supply?”
Verify token metadata before integration
“Before I integrate this token into my app, can you confirm that 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon is a valid ERC-20 and tell me its decimals and name?”
Audit unfamiliar token in a wallet
“My wallet is showing a token at address 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC6 on Arbitrum — what is it called, what's the symbol, and how much is in total supply?”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/evm/token?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
