How this service works
Paste a public wallet address and see, for free, how many open airdrops, rewards, refunds and forgotten balances it can still claim. Read-only: no wallet connection, no signatures.
Output
A JSON object listing each open claim with token symbol, amount, program name, deadline (if any), and an official claim link; plus a count of total open claims and an approximate total USD value across all claimable assets.
Example use cases
Recovering forgotten DeFi rewards
“Check my Ethereum wallet 0x4B20993Bc481177ec7E8f571ceCaE8A9e22C02db for any unclaimed Merkl rewards, Uniswap UNI, or other token distributions I might have missed, and give me the amounts and where I can claim them.”
Pre-tax portfolio audit for unclaimed tokens
“Before I do my crypto taxes, can you pull up all the unclaimed airdrops and reward balances for 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B so I know what claimable income I might be overlooking?”
Checking a newly acquired wallet for claimable assets
“I just imported a wallet I hadn't touched in years — address 0x1234567890abcdef1234567890abcdef12345678 — can you check if there are any open airdrops, refunds, or forgotten token balances I can still claim, and how much they're worth in USD?”
Technical details
Endpoint
GEThttps://northline-unclaimed.northline-c86.workers.dev/v1/report?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a consolidated, multi-protocol unclaimed token report for a single wallet across major programs (Uniswap, Merkl on five chains, Doppler, Drift, CAPX, defunct DEX refunds) with USD estimates and direct claim links in one call. Prefer it over manual per-protocol lookups when you want a single-call answer and only pay if claims actually exist.
Side effects
- Wallet address has zero open claims — request refused before payment is charged
- Invalid or malformed wallet address returns an error
- Unsupported address format (non-EVM, non-Solana) returns an error
- Downstream airdrop data sources temporarily unavailable may cause incomplete results
- Rate limiting or payment failure may prevent report generation
