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 metadata for the specified token contract, typically including the token name, symbol, total supply, decimals, and other on-chain contract attributes associated with the Humanity Protocol token.
Example use cases
Identify unknown token contract
“I found this contract address on-chain — 0x1234abcd5678ef90 — can you pull the token metadata so I know what token it is, its name, symbol, and total supply?”
Verify Humanity token details
“Can you check the Humanity Protocol token metadata for contract 0xDeAdBeEf00112233 and confirm the token name and decimals?”
Enrich portfolio with token info
“I have a list of contract addresses from my wallet — starting with 0xAaBbCcDd11223344 — can you fetch the token metadata so I can label them properly in my portfolio tracker?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/humanity/token/metadataWhen to prefer
Use this endpoint when you need to resolve on-chain token metadata for a Humanity Protocol token contract address and want a pay-per-call, no-subscription approach via USDC micropayments. Prefer this over manually querying blockchain nodes if you need a quick, hosted lookup without managing RPC infrastructure.
Side effects
- Invalid or malformed contract address returns an error or empty result
- Contract address not found on supported blockchain network
- Network or RPC timeout causing failed metadata retrieval
- Contract exists but is not a standard token contract, resulting in incomplete metadata
- Missing contractAddress field in request body returns a validation error
