Podcast Prospect Finder (Podcast Index API)
Find active podcasts by topic and language through the open Podcast Index API, filter out shows that stopped publishing, and export a shortlist to pitch.
Economics
- Pricing example
- $15 for 300 searches and exports (first 20 free)
- Daily math
- 1-2 packs a day x $15 = $15-30/day; about 40 packs a month averages $20/day.
- Target if you hit the daily math
- Target: $500 - $800 / month if the daily math is hit
Audience and urgency
Audience: PR freelancers, authors, consultants and founders who pitch themselves or clients as podcast guests.
Urgency: Many podcasts listed in directories have stopped publishing. Pitchers waste time on inactive shows and struggle to filter by language or region.

One-shot master prompt
Build a "Podcast Prospect Finder" in React with Tailwind CSS and serverless functions using the Podcast Index API. Core requirements: 1. Server functions that sign requests (X-Auth-Key, X-Auth-Date, Authorization SHA-1 hash of key+secret+date) and call search/byterm and podcasts/byfeedid; cache responses for 12 hours. 2. Search page: keyword, language, category, "last episode within" (30/60/90 days), minimum episode count; results table with title, image, website, feed URL, last episode date, episode count, categories. 3. Shortlist: save shows with notes and status (to pitch / pitched / booked / declined), stored in Supabase per user. 4. CSV export of the shortlist. Do not extract or store owner email addresses from feeds; show the website link only. 5. 20 free searches, then Stripe Checkout ($15 for 300). Credit Podcast Index on the page and follow its API terms.
