## 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-796936c2 -d '<json body>'
```

Example prompt: Find me DeFi projects that were funded by Paradigm or a16z in 2024 and are listed on Binance — ideally ones tagged with lending or yield.

## When to prefer this

Use this endpoint when you need to discover or filter across many crypto projects simultaneously using natural language criteria such as investor name, category tags, funding year, exchange listings, or event keywords. Prefer get_project instead when looking up a single known project by exact name, ticker symbol, contract address, or Twitter handle. This endpoint excels at broad discovery across 10k+ projects rather than precise single-entity retrieval.

## Known failure modes

- No matching projects found for highly specific or obscure filter combinations
- New or small projects without VC backing may not be indexed
- Query too vague returns large unfiltered result sets
- Exact single-project lookup by name/symbol/address is better served by the get_project endpoint
- Stale data if a project's exchange listings or funding info changed recently

## 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 including the project name, a one-liner description, relevant tags/categories, known investors, fundraising round details, notable events (e.g. airdrops, launches), and exchange listings. Coverage spans 10k+ indexed projects; very new or unfunded projects may be absent.
