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 Avalanche contract address, typically including the token name, symbol, number of decimals, and potentially additional ERC-20 or ERC-721 metadata fields stored on the contract.
Example use cases
DeFi portfolio token identification
“I have this Avalanche contract address 0x60781C2586D68229fde47564546784ab3fACA982 and I need to know what token it is — can you get the name, symbol, and decimals for it?”
Token explorer enrichment pipeline
“For my on-chain analytics dashboard, fetch the token metadata for Avalanche contract 0xB97EF9Ef8734C71904D8002F8b6Bc66Dd9c48a6E so I can display the token name and symbol next to the wallet holdings.”
Smart contract audit token verification
“I'm auditing a set of Avalanche contracts and need to verify what token is behind address 0x9702230A8Ea53601f5cD2dc00fDBc13d4dF4A8c7 — please pull its on-chain metadata including name, symbol, and decimals.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/avalanche/token/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, pay-per-call token metadata lookups on the Avalanche network without managing your own RPC infrastructure. It is ideal for agents that encounter unknown Avalanche contract addresses and need to identify the token (name, symbol, decimals) in real time. Prefer this over self-hosted solutions when low operational overhead and per-call pricing are priorities.
Side effects
- Invalid or malformed contract address returns an error
- Contract address exists but is not a standard token contract (no metadata methods), leading to empty or error response
- Network congestion or RPC node issues may cause timeouts
- Non-Avalanche contract addresses will not resolve correctly on this endpoint
- Rate limiting or payment failure (x402) if USDC balance is insufficient
