As answered by people managing TTSQL and LinkupAPI.
TTSQL's answer
It is fastest Text to SQL service with both dashboard and API
LinkupAPI's answer:
LinkupAPI is built for AI agents first. One API and an MCP server let Claude, ChatGPT, Gemini or Cursor run LinkedIn, email and WhatsApp outreach directly, across all of a team's accounts, and get every reply back in real time. It is also the only unified outreach API that caps the bill: per-account pricing with unlimited usage, and a flat $3,000 a month for unlimited accounts.
TTSQL's answer
Its cheapest and provides highest free quota
LinkupAPI's answer:
Compared with Unipile and other per-account APIs, LinkupAPI charges the same per connected account up to a few hundred accounts ($55 for 10, then $5.50 to $4.50), but caps the bill at $3,000 a month for unlimited accounts, so it becomes cheaper from about 640 accounts. Compared with LinkedIn automation tools like PhantomBuster, Expandi or Waalaxy, it is an API: your product or AI agent decides who to contact, on which channel and when, instead of running fixed templates. Every account gets a dedicated IP, hosted login and account health alerts.
TTSQL's answer
Developers who willing to integrate advanced search via natural language.
LinkupAPI's answer:
SaaS companies and AI-agent builders that want to add LinkedIn, email and WhatsApp outreach to their product, GTM and sales teams running multichannel outreach from Claude or other AI agents across many accounts, recruiting platforms (ATS) that source and contact candidates, and agencies managing outreach for many clients.
