How credits work

Credits are the currency that powers Iteration Layer. Each API draws from one shared pool — one subscription, one invoice.

Built for agencies and teams

Managing 10 client projects means 10 sets of API keys, 10 usage reports, and no way to cap spend per client. Projects fix that — one account with per-client isolation.

Per-client API keys

Stop sharing one key across clients. Create a project per client, generate scoped keys, and revoke access without touching other projects.

Per-project budget caps

No more surprise overages on a single client. Set a credit limit per project — when one hits its cap, the rest keep running.

One credit pool, one invoice

All projects draw from the same subscription. No per-client billing, no separate invoices, no reconciliation across vendors.

Frequently asked questions

How does the credit system work?

Your monthly plan includes a shared credit pool. Each API request consumes credits from that pool:

  • Document Extraction and Document to Markdown use page-based pricing (see below).
  • Image Generation and Document Generation cost 2 credits per request.
  • Sheet Generation costs 2 credits per request.
  • Image Transformation costs 1 credit per request.
How does page-based pricing work?

Document Extraction and Document to Markdown charge 1 credit per page in your input files.

Estimated costs by page count and plan:

100100$3.00$2.40$2.13
250250$7.50$6.00$5.33
How are pages counted?
  • Images (PNG, JPEG, WebP, HEIF, GIF, SVG) count as 1 page each.
  • PDFs are counted by their actual page count.
  • DOCX, XLSX, CSV, TXT, HTML, MD, JSON each count as 1 page regardless of length.
  • Document Extraction sums pages across all files in the request (up to 20 files per request).
  • Document to Markdown accepts a single file per request.
Is there a free trial?

Yes. Every account gets $65 in free trial credits across all APIs — no credit card required:

  • 500 document extraction pages
  • 500 document-to-markdown pages
  • 150 image transformations
  • 100 image generations
  • 100 document generations
  • 100 sheet generations
What happens when I run out of credits?
Your API requests will return a 402 error. You can switch to Pay As You Go, enable auto overage on your subscription, or upgrade your plan.
Can I switch plans?
Yes. You can upgrade or downgrade your plan at any time. Changes take effect immediately and your next charge is prorated automatically — you only pay for the time on each plan.
What's the billing period?
Plans renew monthly on the anniversary of your subscription start date. Your credit balance resets at the start of each period.
Do unused credits roll over?
Monthly plan credits do not roll over — they reset each billing period. Enable auto overage to seamlessly bill excess usage via pay-as-you-go rates.
What happens if a request fails?
Credits are automatically refunded for any failed request, whether the failure was a client error (4xx) such as a validation failure, or a server error (5xx). No action is needed on your part. This applies to both synchronous and async webhook requests. You only pay for requests we successfully complete.
How does Pay As You Go work?
Pay As You Go lets you use any API without a monthly commitment. You're billed at the end of each month based on actual usage. Volume discounts kick in automatically — the more you use, the lower your per-credit rate. Trial credits are included, just like with subscriptions.
Can I manage multiple client projects?
Yes. Create projects in the dashboard to organize API keys and track usage per client, environment, or team. Each project gets its own API keys, usage tracking, and optional budget cap — all drawing from the same shared credit pool. Agencies managing multiple client engagements can scope keys and monitor spend per project from one account.
How do project budget caps work?
Each project can have an optional budget cap that limits total credit consumption across all API keys in that project per billing period. When a project's budget cap is reached, all requests using keys in that project return a 402 error. The organization's remaining credits stay available for other projects. This gives agencies and teams per-client spend control without managing separate accounts.
