## 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 liquid-leads-local-business-leads-with-checked-emails-b69d0bac
```

Example prompt: Find me 50 dentist leads in Atlanta where emails are required — I want their contact names, phone numbers, and any buying signals like no website or no booking tool.

## When to prefer this

Use this endpoint when you need verified, graded email leads for local businesses filtered by category and geography, especially when buying signals (no website, no booking tool, no payment system, hiring) matter for targeting. Prefer this over generic business directory APIs when email quality grading (A/B/C) is important for deliverability, or when volume pricing matters for large outreach campaigns. Best suited for sales prospecting, agency new-business development, and B2B SaaS lead generation targeting local SMBs.

## Known failure modes

- 402 Payment Required — returned with exact cost quote before any charge is made; agent must complete payment to receive data
- No results found for the specified category/location combination — returns empty array at no charge
- Invalid city or location format — query returns error or empty result
- Limit out of range (must be 1–1000) — returns validation error
- Category term not recognized or too vague — may return zero or low-quality results

## How this service works

Local business leads by category and place: checked email (graded A/B/C), contact name when the email shows one, phone, website, socials and buying signals (no website, booking tool, payment system, hiring). Volume pricing: 1-99 leads: $0.01 each with an email, $0.006 without; 100-499 leads: $0.0075 each with an email, $0.0045 without; 500-1000 leads: $0.005 each with an email, $0.003 without. 1 to 1000 leads per call (default 10); the 402 quotes the exact total; empty answers are free.

## Output

A JSON list of up to 1000 local business records, each containing: email address with quality grade (A/B/C), contact name (when extractable from the email), phone number, website URL, social media profiles, and buying signals indicating gaps such as no website, no booking tool, no payment system, or active hiring. Empty results are free; the 402 payment response quotes the exact total cost before charging.
