How this service works
Routheus: live DEX token prices and best-route swap quotes from a real-time pool-state engine, executable routes with calldata (Permit2), simulation-verified outputs, token metadata, search and pool data on 13+ EVM chains. Pay per call in USDC via x402 — no API keys, no subscription.
Output
Returns a JSON object with ok=true and a data object containing the token's name, symbol, decimals, contract address, and balance_slot details (slot_type and slot_number for eth_call overrides). If the token is unknown, returns ok=false with an error string and no charge is applied.
Example use cases
Validate token before swap
“Before I execute a swap, can you pull the metadata for 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum so I can confirm it's DAI with 18 decimals?”
Display token info in wallet UI
“I'm building a portfolio tracker — fetch the name, symbol, and decimals for 0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599 on Ethereum so I can label it correctly.”
Retrieve storage slot for simulation
“Get the full metadata including balance slot info for 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I need the slot number to run an eth_call balance override in my simulation.”
Technical details
Endpoint
GEThttps://routheus.xyz/%7Bchain%7D/api/tokens/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative on-chain token metadata (name, symbol, decimals, storage slot) for EVM tokens without requiring an API key or subscription — especially useful in DeFi automation pipelines, swap routing, and simulation workflows where balance slot data is needed for eth_call overrides. Prefer over generic blockchain RPC calls when you want structured, pre-validated metadata with pay-per-call USDC pricing via x402.
Side effects
- Unknown or unindexed token address returns ok=false with an error field (no charge applied)
- Invalid chain identifier in path returns an error response
- Malformed token address (not a valid 0x hex address) returns a validation error
- Chain not among the 13+ supported EVM chains returns an error
- Network or upstream pool-state engine timeout may result in a transient 5xx error
