# OP3 podcast analytics OP3 is an open podcast prefix analytics service. A publisher puts `https://op3.dev/e/` in front of their episode audio URL, every download redirects through OP3 first, and that log is the data. It is the only widely used podcast analytics source that is open by default. Apple and Spotify each show a publisher only their own slice. Every tool here is a read. Nothing changes anything. ## Start here Almost every tool needs an OP3 show uuid. If you have a feed URL, a `podcast:guid`, or an op3.dev link instead, run `op3_resolve_show` first. It accepts all of those, including a plain feed URL, and encodes it for you. If a lookup fails or the numbers are zero, run `op3_verify_prefix` before concluding anything. It separates the three cases that look identical from the outside: the prefix was never added to the feed, it was added but nothing has come through yet, or it is working and the number really is small. ## Pick the cheap tool first The rolled-up tools answer in milliseconds because OP3 has already aggregated them. The rest read raw download rows, which is a scan: cost grows with the window, not the row count, and a wide window can take tens of seconds. | Question | Reach for | |---|---| | How many downloads does this show get | `op3_show_downloads` | | How did each episode do | `op3_episode_downloads` | | How do these shows compare | `op3_compare_shows` | | How many actual people | `op3_audience_summary` | | Where are they | `op3_geography` |
