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 structured token metadata for the given Mantle contract address, typically including the token name, symbol, number of decimal places, and total supply — useful for identifying and displaying ERC-20 tokens on the Mantle network.
Example use cases
Identify unknown Mantle token
“I've got a contract address on Mantle — 0x201EBa5CC46D216Ce6DC03F6a759e8E766e956aE — can you tell me what token this is, including its name, symbol, and decimals?”
DeFi dashboard token enrichment
“I'm building a portfolio tracker and need to display token info for 0x0A3BB08b3a15A19b4De82F8AcFc862606FB69A2D on Mantle — fetch me its name, symbol, and decimal places.”
Verify token contract details
“Before I swap on Mantle, can you verify the token details for contract 0xdEAddEaDdeadDEadDEADDEaddEADDEadDEADDEaD — show me the symbol and total supply so I know it's legitimate?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/mantle/token/metadataWhen to prefer
Use this endpoint when you specifically need token metadata from the Mantle blockchain network and want a pay-per-call model without managing your own RPC node or API key subscription. Prefer it over raw RPC calls when you need a simple REST interface for Mantle token lookups.
Side effects
- Invalid or malformed contract address returns an error response
- Contract address does not exist on Mantle network — returns not-found or empty metadata
- Address is a non-token contract (e.g. a DEX pool or NFT) — metadata fields may be missing or unexpected
- Network timeout or upstream RPC failure — transient error
- Payment not fulfilled via x402 — request rejected with 402 status
