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 metadata for the specified token contract, typically including the token name, symbol, and decimal precision. May also include additional contract-level metadata depending on the token standard.
Example use cases
Identify unknown token in wallet
“I see a token at contract 0x1234567890abcdef1234567890abcdef12345678 in my wallet — can you look up its name, symbol, and decimals on Katana?”
Verify token contract before trading
“Before I trade, can you pull the token metadata for 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef on the Katana network so I can confirm it's the right asset?”
Enrich DeFi dashboard with token info
“I'm building a dashboard and need the official name and symbol for the token deployed at 0xaabbccddeeff00112233445566778899aabbccdd on Katana — can you fetch that?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/katana/token/metadataWhen to prefer
Use this endpoint when you need to resolve on-chain token metadata specifically for contracts on the Katana network. Prefer this over generic blockchain explorers when you need a programmatic, pay-per-call API response suitable for agent workflows. It is ideal for DeFi dashboards, wallet applications, or any automation that needs to identify tokens by contract address without scraping block explorer UIs.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a token contract — metadata fields may be missing or empty
- Contract not deployed on the Katana network returns a not-found or null response
- Network or RPC timeout causes a service unavailable error
- Missing contractAddress field in request body returns a validation error
