What problem does it solve? Searching Prospeo's lead database at scale is error-prone: the API caps results at 25,000 per search, enforces strict rate limits, and uses non-obvious filter formats. This Skill documents the correct request structure, filter types, and crawling patterns so lead searches return complete, deduplicated results. ## Core Features & Use Cases - Complete Filter Reference: Covers location, job title, company headcount, industry, technology stack, funding stage, and verified-email filters with exact request formats. - State-by-State Crawling: Splits US-wide searches across all 50 states to bypass the 25K result ceiling per query. - Rate Limiting & Retry Patterns: Provides token bucket throttling at 2 requests/second and exponential backoff for 429 errors. - Use Case: Build a list of marketing VPs at US software companies with 50-200 employees that raised Series A funding in the last 180 days, restricted to verified emails. ## Quick Start Ask the AI to search Prospeo for tech executives at US software companies with verified emails using the Prospeo Search Person API.
