X API Pricing Changed. What Advertisers Should Check.

X offers pay-per-use access to its developer API. Advertisers still need to check Ads API permissions, account access, and the cost of the actions they plan to use.

The pricing change

X now describes its developer API as a credit-based, pay-per-use product. That makes it easier to start small and pay for the API activity you use. The exact charge depends on the endpoint and the current rate shown in X's developer console. See the X Developer Platform overview before estimating a budget.

The change matters if your team reads public posts, publishes content, or uses X data to research a campaign. It does not mean every advertising workflow is available to every developer account.

Developer API and Ads API access are separate checks

X lists the Ads API separately from its pay-per-use developer API. The Ads API is used to manage campaigns, targeting, creative, and analytics. An application also needs the permissions required for the ad account it will manage. X's third-party app guidance describes the separate analytics and campaign-management scopes.

Before you plan around an API price: confirm that your application can reach the Ads API endpoints you need, that the advertiser has authorized the right account, and that the account can run the intended campaign.

What to budget for

Keep three costs separate: developer API usage for X data and posts, the work required to build and review the campaign, and media spend billed by X Ads. A per-post developer API rate is not a campaign management rate or a measure of ad spend.

Estimate the calls and distinct Posts returned in your workflow, then check current prices and rate limits in X's console. X's usage and billing guide explains how returned Posts count toward usage. Check endpoint access before planning a campaign around an API workflow.

How to use Synter for an X campaign

  1. Connect the X ad account and confirm the available permissions.
  2. Give Synter a campaign brief with the audience, budget, creative, and goal.
  3. Review the proposed setup and tracking before approving a launch.
  4. Check delivery and results against the original plan after launch.

Start with a small campaign whose targeting and spend you can inspect. You can get started with Synter when your X account and campaign brief are ready.
