How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object with the queried wallet address, eligibility details for each active airdrop, potential reward amounts, total number of active airdrops checked, number of transactions scanned, and the timestamp of the check.
Example use cases
Portfolio airdrop eligibility scan
“Check my wallet 0x4B20993Bc481177ec7E8f571ceCaE8A9e22C02db for any airdrops I'm eligible to claim right now — I want to know how many active ones there are and what the potential rewards look like.”
DeFi user missed airdrop check
“I've been using DeFi protocols for a while. Can you scan 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B to see if I'm eligible for any current airdrops I might have missed?”
New wallet onboarding airdrop lookup
“I just set up a new Ethereum wallet at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — can you check if it's eligible for any airdrops and how many transactions were scanned?”
Technical details
Endpoint
GEThttps://klymax402.com/api/airdrop-checker/api/checkWhen to prefer
Use this endpoint when you need a quick, pay-per-call airdrop eligibility check for any Ethereum wallet address without managing API keys. Ideal for agents that need on-demand DeFi airdrop lookups without committing to a subscription service. Choose this over manually querying individual airdrop protocols when you want aggregated results across multiple active airdrops in a single call.
Side effects
- Invalid or malformed Ethereum address returns an error
- No eligible airdrops found returns empty eligibility object
- Wallet with no transaction history may return zero scanned transactions
- Network or provider downtime may cause timeout or 5xx error
- Payment failure (insufficient USDC balance) prevents the call from completing
