How this service works
What are the symbol, name, decimals, contract address and issuer of this stablecoin on this chain? Cited stablecoin token facts from a prepared dataset (USDC, EURC, USDT, PYUSD, DAI on the chains /v1/chain covers, where a permissively licensed source lists them): symbol, name, decimals, contract address, chain, issuer, each with a source citation and license. Fields not established from a source are the string "unknown". Malformed input and tokens not in the dataset return 400/404 and are never
Output
A structured object with fields: symbol, name, decimals, contract address, chain, and issuer — each accompanied by a source citation and license. Fields not established from a permissively licensed source are returned as the string 'unknown'. Malformed input or tokens not in the dataset return HTTP 400 or 404.
Example use cases
Pre-payment token address verification
“Before I build the transfer, can you look up the official USDC contract address and decimals on Polygon so I know I'm sending to the right place?”
Cross-chain stablecoin metadata comparison
“What are the token details for USDT on Ethereum versus on Solana — symbol, contract address, decimals, and issuer for both?”
Issuer identity check for compliance
“I need to confirm who issues EURC on Base — can you pull the verified issuer and source citation for that token?”

Endpoint
GEThttps://payments-intel-production.up.railway.app/v1/token?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, citation-backed stablecoin token metadata (contract address, decimals, issuer) for a specific chain before executing payments, building integrations, or verifying on-chain data. Prefer it over general blockchain explorers or web searches when you need structured, machine-readable facts with source provenance for a curated set of major stablecoins (USDC, EURC, USDT, PYUSD, DAI).
Side effects
- 400 returned for malformed chain slug, CAIP-2 id, or token symbol/address
- 404 returned for valid but unsupported token/chain combinations not in the dataset
- Missing required 'chain' query parameter causes 400
- Tokens other than USDC, EURC, USDT, PYUSD, DAI are not in dataset and return 404
- Chains not covered by the dataset return 404
