We strive to keep these prices in line with the ordinary cost of these services. If you believe any of these prices are out of sync with the costs charged by the underlying provider, please let us know. A Platform Service Fee of 30% for Free users, 25% for Hobby users, and 20% for Pro users, is applied to Additional API Usage calls to cover costs.

Dev Services

Anybody can suggest amendments to the Þ specification. The protocol is openly debated and governed, and you don’t need to hire us (in fact, you can’t!) in order to change the spec.

Similarly, anyone can build a Þ block. However, if you’d like a block built for you, or are looking to partner on a particularly complex block, we provide support or can connect you with a community developer.

1:1 Support

We offer dedicated 1:1 premium support with guaranteed SLAs via email and Slack.

  • For embedders integrating the Block Protocol into their application or framework
  • For block developers building complex applications
  • For API providers listing on the Hub
  • For users of blocks who are heavily dependent on them for work

Frequently Asked Questions

Can free users access premium external services?

Free users as well as paying users can benefit from blocks that utilize external services. All free users receive a limited number of credits for use each month, providing free access to ordinarily paid services including OpenAI DALL-E, GPT-3, and Mapbox for free. These allowances are more restrictive than those on the Hobby and Pro plans, but can allow for limited testing and use of services in blocks.

How does overage charging work?

Charges for external services/API usage beyond the allowances included in a plan are billed in line with the rates shown on the pricing page. Every effort is taken to ensure these costs match the prices charged by the original service provider (e.g. OpenAI/Mapbox), and as a result these overage prices may be subject to change at any time. You can view the current active pricing for a service at any time by visiting this page. Upon the issuance of each invoice, a platform fee will be calculated based on the total amount of unpaid overage charges accrued, and appended to your bill. The platform fee you pay varies depending on your account tier:

  • Free - 30%
  • Hobby - 25%
  • Pro - 20%

If you have any additional questions about overage charges, please contact us

A service provider’s pricing appears different to the cost shown on this page - what should I do?

This is an error, and is most likely the result of a change in the price charged by the original service provider. Please contact us, and we’ll send a special something your way as a token of our thanks!

Can I change the payment method associated with my account?

Yes! Provided you already have a payment method associated with your account you can navigate to your Account Billing page and click “Change payment method” in the top-right of the main section. If you see a message that says “Upgrade to get more” instead, you can add a payment method by first upgrading your account to Hobby or Pro.
