Summary
This connects Claude to a remote API that checks crypto wallet addresses against active airdrop campaigns from LayerZero, EigenLayer, and Scroll. You give it a wallet address and it tells you if that address qualifies for any unclaimed token distributions. The server runs as a hosted service over SSE transport, so there's no local setup. Useful if you're building workflows that need to verify airdrop eligibility or track potential token claims across multiple protocols. The codebase is TypeScript and the repository doesn't include much documentation, but the core function is straightforward: wallet in, eligibility status out.

Airdrop Checker API
Check wallet eligibility for active crypto airdrops -- token, value, deadline, claim URL via Etherscan. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
{
"mcpServers": {
"airdrop-checker": {
"url": "https://airdrop-checker.api.klymax402.com/mcp"
}
}
}
Quickstart -- HTTP (x402)
curl "https://airdrop-checker.api.klymax402.com/api/check?address=0x0000000000000000000000000000000000dEaD"
# -> 402 Payment Required, with an x402 payment challenge in the response body
Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.
