How this service works
x402-paid TokenSense routes, with parallel MPP routes under /mpp/*.
Output
Returns a JSON object with the resolved token's Base network contract address, token name, token symbol, chain ID (8453 for Base), number of decimals, verification status, and API pricing information. Includes a success flag and the route path used.
Example use cases
DeFi swap contract resolution
“I'm building a swap and need the exact Base chain contract address for USDC — can you look it up by ticker and confirm if it's a verified token?”
Token metadata enrichment pipeline
“For the ticker WETH, resolve its Base network contract address and give me the token name, decimals, and chain ID so I can populate my token registry.”
Verify unknown token ticker
“Someone just sent me a token with ticker DAI — can you resolve it on Base and tell me if it's a verified contract or not?”
Technical details
Endpoint
GEThttps://x402.wach.ai/resolveTokenWhen to prefer
Use this endpoint when you need to resolve a token ticker symbol to a verified Base network contract address with full metadata (name, decimals, chain ID, verification status). Prefer this over generic blockchain explorers when you specifically need Base-chain token resolution with built-in verification signals and structured JSON output. Ideal for DeFi agents, token registry pipelines, and any workflow that must programmatically map human-readable tickers to on-chain contract addresses on Base.
Side effects
- Ticker not found on Base network — returns success: false with no tokenAddress
- Invalid or empty ticker parameter — request may fail schema validation
- Token exists but is unverified — tokenIsVerified returns false
- Payment failure via x402 protocol — 402 response if USDC payment not completed
- Network or upstream data source unavailable — may return error response
