Identify unknown Ronin token
“I found this contract address on Ronin — 0xa8754b9fa15fc18bb59458815510e40a12cd2014 — can you tell me what token it is, including its symbol and how many decimals it uses?”
DeFi portfolio enrichment on Ronin
“I have a list of Ronin contract addresses from my wallet transactions. Can you look up the token name and symbol for 0x97a9107c1793bc407d6f527b77e7fff4d812bece so I can label it in my portfolio tracker?”
Validate token contract before swap
“Before I swap on a Ronin DEX, can you pull the metadata for contract 0xc6344bc1604fcab1a5aad712d766796e2b7a70b9 to confirm it's the official token I think it is?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ronin/token/metadata?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to resolve token metadata on the Ronin blockchain (the network powering Axie Infinity and Sky Mavis ecosystem). Prefer this over generic multi-chain APIs when you know the asset is on Ronin, or when you need pay-per-call pricing without a subscription.
Side effects
- Invalid or malformed contract address returns an error
- Contract address not found on Ronin network returns empty or error response
- Non-token contract (e.g. NFT, proxy) may return unexpected or incomplete metadata
- Network timeout or RPC failure on Ronin chain
- Payment failure via x402 protocol blocks the request
