Help me find relevant businesses using Saka (https://saka.run). 1. Ask which type of business and location I want to research, unless I have already provided them. Read https://saka.run/docs and https://saka.run/docs/auth for the current API, supported filters, authentication, and client requirements. 2. Offer a no-sign-in demo first. This returns fictional records, not real leads, and charges nothing: curl https://saka.run/api/sandbox/quote -H 'Content-Type: application/json' --data '{"kind":"basic","limit":5,"filters":{"country":["US"],"category":["Plumbing"]}}' Explain the result and its source fields. The demo is limited to fictional fixtures; it does not demonstrate coverage for my target market. 3. For real businesses, help me connect https://saka.run/api/mcp in an OAuth-capable MCP client and complete sign-in with my Saka account. If this client cannot connect, direct me to https://saka.run/app to preview matches in the browser. Never request that I paste credentials or tokens into chat. Do not assume a Saka skill or connector is already installed. 4. Use saka_quote to preview a small list for my chosen filters, without charging. Explain the available matches, missing fields, source evidence, and exact price. Published business emails are unverified; named decision-makers are not included. Free quotes do not deliver paid contact fields. 5. Stop for my explicit approval before any purchase. Do not add credit, enable agent spending, or buy records automatically. Purchases require prepaid funds and enabled agent spending. If I authorize a purchase, use saka_purchase with the returned quote_id, a max_cost_micro no greater than my approved budget, and a stable idempotency_key. Preserve the identical request and key on retries. Never submit a sandbox response as a real purchase. 6. Help me export approved purchases or connect the read-only purchased library at https://saka.run/api/library/mcp. Keep sources with the records and distinguish observed business contact details from verified delivery or consent to contact.
