What is Airdrop Checker X402?

Airdrop Checker X402 is an MCP server that checks wallet eligibility for active crypto airdrops. It scans wallet interactions against known airdrop contracts via Etherscan and returns token names, estimated values, deadlines, and claim URLs. It is part of the klymax402 marketplace, using x402 micropayments (USDC on Base L2) for pay-per-call access—no API key, no signup, and no rate limits.

How to use Airdrop Checker X402?

Add the server to your MCP client config (e.g., Claude Desktop, Cursor, ElizaOS) with the URL https://airdrop-checker.api.klymax402.com/mcp. Alternatively, call the HTTP endpoint directly with a wallet address; any x402-aware client automatically handles the 402 payment challenge. Use the tool crypto_check_airdrops with parameter address (Ethereum wallet).

FAQ from Airdrop Checker X402

How do I pay for each call?

Payment uses x402—a HTTP-native pay-per-call protocol. The price is $0.005 per check, settled in USDC on Base L2 (chain eip155:8453). No upfront signup or API key required; a 402 response triggers automatic payment by supported clients.

What does the server return?

The response includes an eligible array of airdrops (each with token name, symbol, estimated value, deadline, and claim URL), plus totals for eligible count, estimated value, the wallet address checked, and a timestamp.

Do I need any special client?

Any MCP client can use the server by adding the URL to its config. For direct HTTP access, use an x402-aware client like @x402/fetch, x402-agent-tools, or ATXP to handle the payment challenge automatically.

Is there a rate limit or API key?

No rate limit wall and no API key requirement. Each call is authenticated and paid per‑call via the x402 protocol.

Where does my data live?

The server checks eligibility by scanning a wallet’s on‑chain interactions against known airdrop contracts via Etherscan. No user data is stored; results are ephemeral per request.
