Glade API uses a simple unit-based billing model — one successful operation consumes one unit, regardless of interface (REST, GraphQL, or MCP) or whether the data came from a live provider or cache.

​
What counts as a unit

Every successful operation deducts exactly one unit from your balance, no matter how many fields you request or which interface you use:
  • One successful REST call = 1 unit
  • One successful GraphQL operation = 1 unit
  • One successful MCP tool invocation = 1 unit
  • Cache hits = 1 unit (you receive the same product value, freshness is preserved)
  • Internal retries and provider fan-out = 0 additional units (Glade API absorbs these transparently)
You are never charged for errors. Validation errors, auth failures, rate limits, quota failures, provider errors, and timeouts all consume zero units.

​
Plans

Glade API offers four plans to fit every scale of usage. All plans include 100 free units to get started. For full plan details including annual pricing and volume discounts, visit gladeapi.com/pricing.

​
Estimating your usage

Your monthly unit consumption depends on the number of operations you run and the number of marketplaces you query. Example: If you fetch product details for 1,000 ASINs daily across 2 marketplaces, that is 2,000 units per day or approximately 60,000 units per month. A few reference points to help you plan:
  • The Premium 20K plan covers approximately 666 products per day if you fetch each ASIN from a single marketplace (20,000 units ÷ 30 days).
  • If you query the same ASIN across two marketplaces, that halves your daily ASIN budget to ~333 products per day on Premium 20K.
  • For workloads that mix product lookups, search queries, and offer checks, count each operation individually — they each consume one unit.
Use the volume calculator at gladeapi.com/pricing to model your specific usage pattern before committing to a plan.

​
Handling quota errors

When you exhaust your unit balance on a Hobby plan or any plan with a hard cap enabled, Glade API returns an HTTP 402 response. Your request is not fulfilled and no additional units are deducted.
To resolve a quota error:
  • Hobby plan: Upgrade to Pay as you go to unlock per-unit overage billing and eliminate the hard cap.
  • Pay as you go or Premium: Overage billing kicks in automatically — you will not hit a hard cap unless you have manually enabled one in your dashboard.
  • Enterprise: Contact your account manager to adjust your quota or enable a hard cap for cost control.
