Pricing & quotas

Every scrape spends credits from a monthly pool tied to your plan. Each plan also caps how many scrapes you can run at once. Both limits are enforced on the /scrape (and /map) hot path.

Credit cost per engine

Cost is charged per URL, keyed by the engine you request (a multi-URL request costs the sum). The weights track real infrastructure cost — a plain fetch is the floor, an AI exploration pass adds model tokens, and a Chromium session is the expensive part.

Engine	Credits / URL
`html`	1
`ai-html`	3
`browser`	5
`ai`	5
`ai-browser`	10

ai auto-resolves to the html or browser runner at request time, but that’s unknown when we charge, so it’s priced at the browser tier — it’s not a cheap path to a browser run. Caching a generated AI plan and POSTing it back as deterministic actions drops the per-run cost to the underlying engine’s rate (1 or 5).

Plans

credits is the monthly pool (reset at the start of each UTC month, no rollover); concurrency caps simultaneous in-flight scrapes per user. New accounts start on free.

Plan	Price / mo	Monthly credits	Concurrency
`free`	$0	1,000	2
`starter`	$49	25,000	5
`growth`	$149	150,000	15
`scale`	$499	750,000	40

Manage your subscription on the billing page. The same catalog is available programmatically at GET /billing/plans.

Checking usage

GET /usage (Clerk-authenticated, like the rest of /me/*) returns the current period’s quota state:

{
  plan:             'free' | 'starter' | 'growth' | 'scale';
  period:           string;   // UTC "YYYY-MM"
  creditsLimit:     number;
  creditsUsed:      number;
  creditsRemaining: number;
  concurrencyLimit: number;
}

The dashboard’s billing page is a visual wrapper over this.

Hitting a limit

Status	Body	Cause
`402`	`{ "error": "credit quota exceeded", "creditsLimit", "creditsUsed", "creditsRemaining": 0 }`	The request would exceed your monthly credit pool. Upgrade your plan or wait for the next period.
`429`	`{ "error": "concurrency limit exceeded", "concurrencyLimit" }`	Too many scrapes already in flight for your account. A `Retry-After: 5` header is set — back off and retry.
