Airdrop Checker API

br0ski777/airdrop-checker-x402

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.
