x402
Orbit Chain Reads: ERC-20 Token Metadata is a paid API for AI agents from orbit-chain.orbit-builder.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).
Fetches on-chain ERC-20 token metadata (name, symbol, decimals, total supply, bytecode size, optional holder balance) from Base, Ethereum, Arbitrum, Optimism, or Polygon.

How this service works
ERC-20 token metadata, $0.001 USDC per call: ERC-20 metadata read directly from the contract on Base, Ethereum, Arbitrum, Optimism or Polygon: name, symbol, decimals, total supply (raw + decimal), bytecode size, and optionally one holder's balance. Non-contract address returns 404 (not charged). Raw chain data, no price or risk opinion. No params = runs the example input.
Output
Returns a JSON object with the token's on-chain name, symbol, decimals, raw total supply, human-readable total supply, bytecode size, and (if a holder address was provided) that holder's token balance. Returns 404 (uncharged) if the address is not a deployed contract.
Example use cases
Verify token details before DeFi trade
“Before I swap, can you check the name, symbol, and decimals for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum so I know it's actually DAI?”
Check holder balance for portfolio tracking
“What's the USDC balance of wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base — look up the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913?”
Audit new token contract on Arbitrum
“I want to verify a new token listing — can you pull the on-chain metadata for contract 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum, including total supply and bytecode size?”
Technical details
Endpoint
GEThttps://orbit-chain.orbit-builder.workers.dev/v1/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need raw, trustless on-chain ERC-20 metadata directly from the contract without any price data, risk scoring, or third-party enrichment. Ideal for verifying token identity, checking decimals before a calculation, confirming total supply, or reading a specific holder's balance across Base, Ethereum, Arbitrum, Optimism, or Polygon at very low cost ($0.001 per call).
Side effects
- 404 returned for non-contract addresses (EOAs, undeployed addresses) — not charged
- Invalid or malformed contract address returns an error
- Unsupported chain name returns an error
- Network/RPC timeouts for congested chains
- Token contract that doesn't implement standard ERC-20 interface may return partial or missing fields
