How this service works
Coinlight charges USDC per API call with the x402 protocol on Solana and Base.
Output
Returns JSON indicating the address type (Solana base58 or EVM 0x), whether the address is valid, and the EIP-55 checksummed version for EVM addresses, allowing downstream processes to safely proceed or flag errors.
Example use cases
Pre-transfer address safety check
“I'm about to send ETH to 0xa30f3c68f2f6067EE5B9d5f651426E44ea8aDaE9 — can you verify it's a valid EVM address and give me the EIP-55 checksum form so I know it's not a typo?”
Identify unknown address chain
“Someone gave me this address: DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 — can you tell me if it's a Solana or Ethereum address and whether it looks valid?”
Catch user-entered wallet typo
“A user pasted this wallet address into our app: 0xABcD1234 — check if it's actually a valid EVM address or if they made a mistake before we try to send funds.”
Technical details
Endpoint
GEThttps://coinlight-app.vercel.app/p/address-validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent or application needs to validate a user-supplied crypto address before executing any on-chain transaction, especially when the address source (Solana vs EVM) is uncertain. It is ideal for pre-flight checks in wallet UIs, agent payment flows, or any form where a user types a destination address manually.
Side effects
- Empty or missing 'address' query parameter returns an error
- Completely non-address strings may return invalid with no type detected
- Very long or binary-encoded strings may produce unexpected results
- Network timeout on the Vercel deployment under high load
