Search Aggregator deep tier: Tavily+Exa+Firecrawl merged results with full page content and synthesized answer, fixed price $0.05 USDC.

Search and read in one call: a web search plus the full page text of the top results, for $0.006 — cheaper than a separate search and reads. Send a query, get back compact results (position, title, url, snippet) each enriched with the target page's readable content (markdown or text, capped by max_chars_per_page). A page that fails to read carries a read_error instead of content; the call still delivers and settles. USDC on Base, no account.

Search Apollo database for people matching filters. Returns up to 100 results per page. Does not include emails/phones - use enrichment endpoints for that.
