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 attestation and metadata for the specified token contract, including details about the token's on-chain state and any attestation records associated with that contract address on the requested chain (Base, Ethereum, or Solana).
Example use cases
Verify Ethereum token contract legitimacy
“Can you pull the on-chain attestation info for this Ethereum ERC-20 contract — 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — so I can check if it's legitimate before interacting with it?”
Fetch Solana SPL mint metadata
“Get the attestation data for this Solana SPL mint address: EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — I want to verify the token details on-chain.”
Enrich Base token data for a DeFi dashboard
“Fetch the on-chain token info for the Base contract 0x4200000000000000000000000000000000000006 so I can display verified token metadata on my dashboard.”

Endpoint
POSThttps://attest.tollkit.dev/chain/token?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need on-chain token attestation or metadata for a specific ERC-20 or SPL mint address on Base, Ethereum, or Solana, and you want frictionless per-call access without setting up an account or API key — ideal for agents that pay in-band via x402 USDC micropayments.
Side effects
- Invalid or malformed contract address returns a validation error
- Token address not found on specified chain returns empty or not-found response
- Insufficient USDC payment via x402 causes payment rejection before data is returned
- Wrong chain specified for a given address type (e.g. Solana address with Base chain) returns an error
- Network or RPC unavailability may cause timeout or 5xx errors
