Plans & meters

Everything buyers can purchase is configured in the ZeroClick dashboard: products, plans, meters, pricing, and entitlements. If you'd rather not set this up yourself, the ZeroClick team can configure your catalog for you. The contract on your side stays the same either way.

Products#

A product is something you sell from a service, for example "Weather API – Standard Access". Each product has a shape that determines its billing model:

Shape	In short
Pay as you go	No base fee; every unit of usage is billed at the meter price.
Subscription	A recurring fee for access and entitlements; no metering required.
Subscription + included usage	A recurring fee that includes usage, with overage billed per meter.
Prepaid credits	Buyers purchase a balance upfront; usage draws it down.

See Product shapes for how to choose and how each one behaves at the metering level.

Meters#

A meter is a usage dimension you measure on a product:

Label: the human-readable name, e.g. "API requests". The kebab-cased label (api-requests) is what you reference when reporting usage.
Unit: what one unit means, e.g. "request", "run", "token".

Define a meter for each thing you charge for. Most APIs need only one or two.

Plans#

A plan is a pricing tier within a product, such as Starter or Scale. Plans have:

Field	Description
Billing interval	`none`, `month`, or `year`. Use `none` for one-time purchases such as prepaid credits.
Base price	The recurring (or one-time) price in USD.
Included credits	Optional. A USD allowance included in the base price.
Credit expiry	Whether included credits `expire` at the end of each period or `rollover`.
Spend cap	Optional. The most a buyer can spend in a period, including overage. ZeroClick notifies you and the buyer when it's reached; your API then returns the 402 exhaustion response for paid actions.

Per-meter pricing#

Each plan prices each meter:

Unit price: USD per unit (or per bundle).
Bundle size: units sold together. A bundle size of 1,000 with a unit price of $0.10 means $0.10 per 1,000 units.
Included units: units covered by the base price before overage pricing kicks in.

Entitlements#

Entitlements are key-value flags attached to a plan, such as support: priority or max-resolution: 4k. They're delivered to you with the API key exchange call, so your API can gate features by plan without hard-coding plan names.

What buyers see#

Your catalog is published at the proxy:

GEThttps://{service-slug}.pay.zeroclick.io/plans

Agents fetch this endpoint to compare plans and purchase one. Plan names, descriptions, prices, included usage, and meters are all visible. Write them for a buyer deciding what to purchase.

You can also serve the storefront and proxy from a subdomain of your own site, such as agents.example.com. See Use your own domain.
