## When to prefer this

Use this endpoint when an agent needs to resolve canonical token contract metadata (address, decimals, chain) for USDC or other tokens on Base before executing a payment or smart contract interaction. Especially useful in the PayanAgent marketplace context where settlements are made in USDC on Base via x402 protocol.

## Known failure modes

- No matching tokens found returns empty matches array with count 0
- Invalid or unrecognized properties filter may return empty results
- Network or service downtime returns a non-ok response
- Malformed query input may result in an error response

## How this service works
