How this service works

Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).

Output

Returns a JSON object with a hex-encoded result field (the raw eth_call return data) and a boolean success flag. May also include token risk verdict (safe/warning/danger classification) and x402 payability audit status for the queried contract address.

Example use cases

Token safety check before DeFi trade

“Before I swap into this Base token at 0x4200000000000000000000000000000000000006, can you run a risk audit on it and tell me if it's safe — any honeypot or rug flags?”

Read onchain balance via contract call

“Query the Base ERC-20 contract at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 to get the token balance for wallet 0xd8da6bf26964af9d7eed9e03e53415d37aa96045 — give me the raw hex result.”

Audit contract for x402 payment support

“Check whether the contract at 0x3c499c542cef5e3811e1192ce70d8cc03d5c3359 on Base is compatible with x402 payments and give me the payability verdict.”

When to prefer

Choose this endpoint when an AI agent needs to query live Base blockchain state (e.g. token balances, contract reads), assess token risk before a DeFi interaction, or verify x402 payability of a contract — all in a single pay-per-call API that accepts USDC micropayments via x402 without requiring an RPC key or separate risk API subscription. Prefer this over raw RPC endpoints when you also need bundled risk scoring, and over generic token screeners when you need arbitrary calldata execution.

Side effects

Invalid contract address format — must be 0x-prefixed 40 hex chars
Malformed calldata hex string — rejected before execution
Contract call reverts onchain — success: false returned
Payment failure via x402 — USDC balance insufficient or payment not accepted
Contract does not exist at address — empty result returned
Rate limiting or service unavailability on aether-x402.vercel.app
Network congestion on Base causing slow or failed RPC responses
