How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
Returns a JSON object with token metadata fields such as token name, symbol, decimals, and other ERC-20 contract-level information for the specified contract address on the requested EVM network.
Example use cases
Identify unknown token contract
“I found this contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — can you tell me what token it is, its symbol, and how many decimals it uses?”
DeFi portfolio token enrichment
“I have a list of ERC-20 contract addresses on Arbitrum and I need the name and symbol for each one — start with 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8.”
Cross-chain token research
“What are the token details for 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619 on Polygon? I want to know the full name, ticker symbol, and decimal precision.”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/token/meta?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain ERC-20 token metadata (name, symbol, decimals) for a specific contract address on EVM-compatible networks including Base, Ethereum, Arbitrum, Optimism, Polygon, or BNB Chain. It is best suited for lightweight, per-token lookups rather than bulk indexing.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty result
- Unsupported network name causes a validation error
- Contract address not found on the specified network returns failure
- Malformed 0x address format rejected by schema validation
- Network RPC unavailability may cause timeouts
