# Vextorium Airdrop Candidates

> Vextorium Airdrop Candidates is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-28).

Returns a ranked list of DeFi protocols with high TVL but no token yet, surfacing likely airdrop candidates sourced from DefiLlama

## 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 vextorium-airdrop-candidates-c9e5e646 -d '<json body>'
```

Example prompt: Show me the top 10 DeFi protocols on Ethereum with at least $50M TVL that haven't launched a token yet — I want to find the best airdrop farming opportunities.

## When to prefer this

Use this endpoint when you want a curated, signal-based list of DeFi protocols likely to airdrop, filtered by TVL and network, without manually scraping DefiLlama. Prefer this over manual research when building airdrop farming workflows, agent-driven portfolio strategies, or community airdrop newsletters.

## Known failure modes

- Missing required 'input' wrapper object returns validation error
- Invalid network string returns empty candidates list
- Extremely high min_tvl filter returns zero candidates
- DefiLlama data may be stale if upstream source is delayed
- Rate limit exceeded returns HTTP 402 or payment error

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object containing a list of candidate protocols, each with project name, website, Twitter, DefiLlama link, TVL in USD, supported networks, DeFi category (e.g. CDP, RWA), task description for earning the airdrop, and difficulty level. Also includes a total count and a disclaimer note that these are signals, not confirmed airdrops.
