How X prices API reads

X moved its API to pay-per-use pricing in 2026: instead of a monthly tier, you buy credits and each record you read is charged. Reading a post costs $0.005; a user profile, and each record in a follower or following list, $0.01. Reads are capped at 3,000,000 posts a month, after which X asks for an enterprise contract. The rates come from X’s pricing page, checked October 2026.

What the estimate leaves out

It counts reads only. X charges separately for creating posts, and it de-duplicates some repeated reads within a day, so a workload that re-reads the same posts may cost less than shown. On Weir, the per-request credit assumes default page sizes; larger pages need fewer requests and cost slightly less.

For the full breakdown, read X API pricing in 2026, or see Weir’s pricing.

Questions

How much does the X API cost per post?

On X's pay-per-use plan, reading a post costs $0.005, which is $5 per 1,000 posts. A user record and a follower or following record cost $0.01 each (checked October 2026).

Is there a limit on how much I can read?

Pay-per-use reads are capped at 3,000,000 posts a month; beyond that X requires an enterprise agreement.

Does this include posting?

No. The calculator covers reads only, which is what data, research and monitoring workloads spend on. X prices writes separately.

How is the Weir estimate worked out?

Each result costs its credits (an X post 1, a profile 2, a follower record 1), plus one credit per request at default page sizes, less the 5,000 free monthly credits, priced between the largest and smallest credit packs.
