threadapi sells credit packs. There is no subscription: packs add to one balance and never expire.

What a request costs
One credit is one page of Reddit:
| Request | Credits |
|---|---|
| Post with up to 500 comments | 1 |
| Each further 100 comments, or part of 100 | 1 |
| Any listing page, up to 100 items: subreddit posts or comments, search, user posts or comments, subreddits, duplicates | 1 |
| Comment search, one page | 1 |
| Things, up to 100 posts and comments | 1 |
| Subreddit about or User | 1 |
| A running monitor, per day (up to 20 keywords) | 10 |
| Monitor matches, webhook deliveries, and managing monitors | 0 |
| Any failed request | 0 |
- A post request asks for 200 comments unless you set
max_comments, so it costs 1 credit.max_comments=1000costs at most 6. - You pay for the comments a response returns, not for the requests threadapi makes to produce it. Retries on our side are never billed.
- A response served from cache costs the same as a fresh one.
- If your balance covers fewer pages than you asked for, you get what it covers and
meta.limited_by_balanceistrue. The balance never goes below zero. - MCP tool calls cost the same as the routes they call. The playground in the dashboard is billed like a key.
X-Credits-Usedon every successful response says what it cost; the logs list each request.
Monitors
A monitor charges 10 credits when you create or resume it, then 10 credits every 24 hours while it runs (up to 20 keywords, matches free). Pausing or deleting it stops the charges. When a renewal finds insufficient credits, the monitor stops until you add credits and resume it.
How many monitors you can run depends on the largest pack you’ve bought:
| Monitors | Matches per monitor per day | |
|---|---|---|
| Free | 1 | 200 |
| $9 pack | 5 | 1,000 |
| $29 pack | 20 | 1,000 |
| $79 pack | 50 | 1,000 |
Low-balance emails say how many days your running monitors have left.
Refunds
Within 14 days of buying a pack, if none of its credits were used. Email hello@threadapi.dev.
