# Drip API

> Paid API for searching and summarizing premium financial newsletters and podcasts.

Drip provides paid access to synthesized summaries from premium financial
newsletters, blogs, and podcasts. Discover content by topic, then pay per
article to unlock a synthesized summary. Built for AI agents and developers.

**Base URL:** `https://dripstack.xyz`

## How it works

1. **Search** — discover articles, podcasts, and stock-picker calls by topic
   across every indexed publication (free).
2. **Pay & unlock** — fetch a specific post and pay a micropayment to receive
   its synthesized summary. Paid routes return HTTP `402` until payment is
   provided, via the [x402 or MPP](/concepts/payment-flow) protocols.
