How this service works
Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.
Output
Returns on-chain token metadata for the specified contract or mint address, including details such as token name, symbol, decimals, and other chain-specific attributes available for that token on the requested blockchain.
Example use cases
Identify unknown token in wallet
“I see this contract address 0x4200000000000000000000000000000000000006 in my Base wallet — can you look up what token it is, what the symbol is, and how many decimals it uses?”
DeFi app token enrichment
“I'm building a DeFi dashboard and need to display token info for the Ethereum contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — fetch the on-chain metadata like name, symbol, and decimals for me.”
Solana SPL token metadata fetch
“Can you pull the token metadata for Solana mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v? I need the name and symbol without having to set up any API account.”

Endpoint
POSThttps://data.tollkit.dev/chain/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain token metadata for a specific ERC-20 or SPL token and want to avoid setting up an account or managing API keys — payment is handled inline via x402 USDC micropayments. Ideal for lightweight, ad-hoc token lookups on Base, Ethereum, or Solana in agentic or automated workflows where traditional API key management is impractical.
Side effects
- Invalid contract address format returns a validation error
- Token address not found on the specified chain returns a 404 or empty result
- Incorrect chain specified for the address type (e.g., Solana address on Base) causes a mismatch error
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Network or RPC node errors for the specified chain may cause timeouts
