How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns on-chain token metadata for the specified Ink network contract address, typically including the token name, symbol, decimal precision, and potentially other contract-level metadata fields derived from the deployed ERC-20 or similar token standard.
Example use cases
Identify unknown token contract
“I found this contract address on the Ink network — 0x4e3f...8a2c — can you tell me what token it is, its symbol, and how many decimals it uses?”
DeFi app token display enrichment
“I'm building a wallet UI and need the name and symbol for the token at contract 0x9d7c...1f4b on Ink so I can display it correctly to users.”
Verify token details before swap
“Before I execute this swap on Ink, can you confirm the token metadata for contract 0x2a8d...cc91 — I want to make sure I have the right symbol and decimal precision?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ink/token/metadataWhen to prefer
Choose this endpoint when you specifically need token metadata from the Ink blockchain network and want a pay-per-call model with no subscription. It is ideal for agents that need on-demand, low-cost token lookups on Ink without committing to a monthly API plan. Prefer alternatives if you need metadata across many chains simultaneously or need historical token data rather than current on-chain state.
Side effects
- Invalid or malformed contract address returns an error or empty result
- Contract address exists but is not a token contract (e.g. a multisig or proxy) may return null fields
- Ink network RPC unavailability causes timeout or 5xx error
- Payment failure via x402 protocol blocks the request before execution
- Contract address on a different chain (not Ink) returns no data or incorrect metadata
