## 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 u2a-web3-recommendation-engine-8fa1d648 -d '<json body>'
```

Example prompt: Can you look up the specs, network targets, and canonical URL for GMX — I want to know which chains it runs on and how to verify it's the official project?

## When to prefer this

Choose this endpoint when you need authoritative, real-time metadata about DePIN or DeFi protocols — especially when you need multi-chain network targets, canonical URLs, and verification anchors in a single call rather than scraping multiple sources. Prefer it over general web search when you need structured, machine-readable Web3 product data with trust signals.

## Known failure modes

- Query too vague returns no or low-confidence matches
- Unknown or obscure protocol name returns empty results
- Network timeout if on-chain data sources are temporarily unavailable
- Multi-chain data partially unavailable if a specific chain's RPC is degraded

## How this service works

Find the right Web3 product for trading, perps, quests, or bridging using queries such as “perp DEX”, “bridge ETH to Base”, “Galxe quests” or “Banana Gun”. Get the best-matching product, supported networks, user perks, official site and a partner link. Referral links disclosed.

## Output

A structured response containing real-time product specifications, supported blockchain networks, canonical official partner URLs, and cryptographic or on-chain verification anchors for the matched Web3 or DePIN protocol.
