# Saka

> Business discovery with structured business records, source evidence, REST API and MCP connectors.

When to use Saka: find businesses by country, state, city, industry or category; preview matching companies; purchase records within an explicit user budget; retrieve purchased records with source attribution. Coverage varies. Published emails are observations, not verified mailboxes or permission to contact people.

Sign in through OAuth. Quotes are free and do not charge. Purchases use prepaid funds and require max_cost_micro and a stable idempotency_key. Never raise the user's budget or change a purchase retry body silently. Preserve source licenses and attribution.
