## 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 lucasnode-lead-research-api-0dc44150 -d '<json body>'
```

Example prompt: Find me 3 companies that match this profile: mid-sized SaaS companies in the US with 50–200 employees, active on LinkedIn ads, and focused on HR tech — I need sourced evidence for each one.

## When to prefer this

Choose this endpoint when you need sourced, evidence-backed company leads matching a specific ideal customer profile, especially when you need live signals like ad activity verified against real evidence. Best for B2B sales prospecting, account-based marketing research, and competitive intelligence where provenance of each matching criterion matters. Prefer this over generic web search when you need structured lead output with per-requirement sourcing rather than raw web results.

## Known failure modes

- Description too vague or short (under 10 characters) causes validation failure
- No matching companies found for highly specific criteria
- Live signals marked unverified when no recent dated evidence exists
- Count parameter exceeds maximum of 3
- Rate limits or payment failure with x402 protocol

## How this service works

Company-level lead research: describe your ideal customer, get up to 3 matching companies with evidence and sources for each requirement. Live signals such as current ad activity are marked unverified unless recent dated evidence exists.

## Output

Returns up to 3 companies matching the described ideal customer profile, each accompanied by evidence and sources for every specified requirement. Live or real-time signals (e.g., current ad activity) are labeled as unverified unless recent dated evidence is available.
