How this service works
Search supported ERC-20 tokens by symbol or address across 6 chains (Base, Ethereum, Arbitrum, Polygon, BSC, Avalanche). 5000+ tokens from CoinGecko.
Output
Returns a list of matching ERC-20 tokens with their symbol, contract address, chain ID, and metadata for tokens matching the search query on the specified chain — drawn from a CoinGecko-sourced dataset of 5000+ tokens across Base, Ethereum, Arbitrum, Polygon, BSC, and Avalanche.
Example use cases
Example prompt
“Search for the token USDC on Base (chain ID 8453) and give me its contract address and any other details you find.”
Technical details
Endpoint
GEThttps://x402-trading.useotto.xyz/supported-tokensWhen to prefer
Use this endpoint when you need to resolve a token symbol to a contract address (or vice versa) across major EVM chains before executing a trade, portfolio lookup, or DeFi operation. Prefer this over on-chain queries when you need fast, pre-indexed token discovery without RPC calls. It complements the sibling trading and portfolio endpoints on the same platform.
Side effects
- No tokens found matching the search term on the specified chain — returns empty tokens array
- Invalid or unsupported chain ID provided — may return empty results or error
- Malformed 0x address in search param — may return no matches
- Payment failure via x402 protocol — request blocked before reaching token lookup logic
- Rate limiting or quota exhaustion — request rejected
