## How to call it through Zero

```sh
zero fetch --capability northline-unclaimed-crypto-report-91039d04
```

Example prompt: Can you check if my wallet 0x4B20993Bc481177ec7E8f571ceCaE8A9e22C02db has any unclaimed airdrops, forgotten balances, or DeFi rewards I can still claim — including things like Uniswap UNI or Merkl distributions — and tell me the total USD value?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
