How this service works
Sylphy helps wallets, apps, and AI agents execute payments and settlements with encrypted intent, policy checks, and audit proofs — while final settlement remains verifiable on Base.
Output
A JSON object containing the token's name (e.g. 'USD Coin'), symbol (e.g. 'USDC'), contract address, and decimal precision (e.g. 6) for the specified ERC-20 contract on Base.
Example use cases
Example prompt

Technical details
Endpoint
GEThttps://api.sylphyagent.com/api/token/%7Baddress%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a raw ERC-20 contract address on Base to its human-readable token metadata (name, symbol, decimals) — especially useful before executing trades, payments, or settlements where you need to confirm token identity and precision.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not an ERC-20 token may return empty or null fields
- Address not deployed on Base network may return 404 or empty result
- Network congestion or RPC issues may cause timeouts
- Payment of 0.01 USDC not provided results in 402 Payment Required
