How this service works
Returns ERC-20 metadata for a Base token, including address, symbol, name, and decimals.

Example use cases
Example prompt

Technical details
Endpoint
GEThttps://fathom-api.mioku-fathom.workers.dev/v1/metadataWhen to prefer
Use this endpoint when you need basic ERC-20 token metadata (name, symbol, decimals) for a known contract address on the Base network. Ideal for enriching token display information, validating token identity, or preparing data for DeFi operations. Prefer this over the sibling price endpoint when you only need token descriptive metadata rather than pricing or liquidity data.
Side effects
- Invalid or malformed token address (not matching 0x + 40 hex chars) returns a validation error
- Token address not found on Base network returns an empty or error response
- Payment of 0.001 USDC not provided results in HTTP 402 Payment Required
- Network or Cloudflare Worker downtime causes service unavailability
