Lead generation
Your agent finds the companies with the contacts published on their sites, checks what they run on, and confirms the emails work. Each tool is priced on its own, so it only pays for what it uses.

}Payment runs through Stripe, which is the merchant of record and handles your card, tax and receipts. Unstuck never sees your card details.
Just one approval. When it reaches a paid tool, you tap Connect, choose $10, $20 or $50, and it continues on its own.
You are only charged when a tool returns a result. Failed calls cost nothing.
No. Credit stays until you use it, and unused credit is refundable within 30 days of purchase.
Claude, Cursor and other apps that support MCP connectors. ChatGPT works too, as a custom connector. Developers can also call the REST API directly.
