## 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 heurist-mesh-semantic-search-crypto-projects-973a88cf -d '<json body>'
```

Example prompt: Find me DeFi projects that were funded by Paradigm or a16z in 2024 and are listed on Binance — I want their names, one-liners, and any upcoming airdrop events.

## When to prefer this

Use this endpoint when you need to discover or filter across a large corpus of crypto projects using multi-dimensional criteria (investor, tag, funding year, exchange, event type). Prefer this over get_project when you don't have an exact project name/symbol/address and want to explore a category or find projects matching investment or event criteria. Best for research, portfolio scouting, and trend discovery across 10k+ projects.

## Known failure modes

- No matching projects found for overly specific or obscure criteria
- Missing data for new, small, or VC-unbacked projects
- Ambiguous natural language queries may return loosely relevant results
- Payment failure if insufficient USDC balance (x402 protocol)
- Rate limiting or timeout for very broad queries spanning many filters

## How this service works

Search crypto projects using natural language criteria. Supports investor filters, tag/category filters, funding years, event years, exchange listings, and event keywords. You can combine multiple constraints in one query. Example queries: 'DeFi projects funded by Paradigm in 2024', 'AI projects listed on Binance with airdrop events in 2025'. Returns matching projects with relevant fields (name, one_liner, tags, investors, fundraising, events, exchanges). Best for discovery and filtering across 10k+ indexed projects. New or small projects without VC backing might be missing. For single project lookup by exact name/symbol/address/twitter, use get_project instead.

## Output

Returns a list of matching crypto projects, each with fields including project name, one-liner description, tags/categories, investor names, fundraising round details, notable events (e.g. airdrops, token launches), and exchange listings. Optimized for discovery across 10,000+ indexed projects; may not include very new or small unfunded projects.
