Reddit API cost comes down to two billing models. The official Reddit Data API is subscription-style: the free tier is rate-limited and gated to non-commercial use, and anything past that runs through a commercial agreement priced at a reported $0.24 per 1,000 calls, after an app-review and approval step. Redditapis is pay-per-call: you pay only for the requests you make, with no monthly fee, no minimum spend, and no approval to clear.
The per-call rate tracks how expensive each request is to serve. Reads are $0.002 because they hit cached, high-volume data. Writes cost more ($0.005 votes, $0.012 comments and profile edits, $0.025 DMs) because they need authenticated sessions, captcha solving, and residential proxies. Credits never expire, so a $10 top-up can stretch across years of low-volume usage. At $0.002 a read with no minimum, this is also the cheapest Reddit API for high-volume reads.
Is the Reddit API free? Reddit's own API has a free tier, but it is capped at roughly 100 queries per minute and is not licensed for commercial workloads without approval. Redditapis is not a flat-free service; it is pay-per-call with $0.50 in free credits at signup so you can test every endpoint before paying.
