# DeFi Airdrop Candidate Scanner

> DeFi Airdrop Candidate Scanner is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-16).

Returns a ranked list of DeFi protocols with high TVL and no token yet, flagging them as potential future airdrop candidates with suggested on-chain activities and difficulty ratings.

## 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 defi-airdrop-candidate-scanner-aa183e09 -d '<json body>'
```

Example prompt: Show me the top 20 DeFi protocols with no token yet and at least $50M TVL that could be airdrop candidates — I want to see what activity to do on each one and how hard it is.

## When to prefer this

Choose this endpoint when you need a curated, up-to-date signal list of tokenless DeFi protocols worth farming for potential future airdrops, sourced from DefiLlama TVL data. It is ideal for agents automating airdrop research workflows, filtering by chain or minimum TVL, and providing human-readable activity suggestions with difficulty ratings — rather than building this aggregation manually from raw DefiLlama APIs.

## Known failure modes

- Missing required 'input' wrapper object returns validation error
- Invalid bodyType enum value causes request rejection
- tvl_min set too high may return zero candidates
- Network/chain filter ('red') not matching any protocols returns empty candidatos array
- Payment failure (insufficient USDC) blocks access entirely

## How this service works

DeFi protocols with significant TVL and no token yet (potential future airdrops): category, suggested activity and difficulty, chains, TVL and links. Signals only, not confirmed airdrops. DefiLlama data.

## Output

A JSON object containing a disclaimer note (signals only, not confirmed airdrops), a total count of candidates, and an array of protocol objects each with: project name, category (e.g. CDP, RWA, Dexs), TVL in USD, suggested on-chain task to qualify, difficulty level (fácil/media/difícil), supported chains, website URL, Twitter URL, and DefiLlama profile URL.
