## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability scriptmasterlabs-airdrop-check-api-e0eafeb7
```

Example prompt: Can you check if the wallet address 0xAbC123...def456 is eligible for or has already received any airdrop — I want to know before I bother claiming.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.001 USDC) on-chain airdrop eligibility check for a specific wallet address and are already operating within an x402 micropayment infrastructure on Base. Best suited for agents that handle crypto portfolio management or DeFi workflows and need programmatic airdrop verification without a full blockchain indexer.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Address not found in any airdrop snapshot returns no eligibility
- API returns empty example response due to sparse schema documentation
- Payment failure via x402 prevents the call from completing
- Render.com hosting may cause cold-start latency or downtime for the free-tier deployment

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns airdrop eligibility or claim status for the queried wallet address, potentially including token allocation amounts, claim deadlines, and whether the airdrop has already been claimed. Response structure is minimal based on available schema.
