description: >-
  Airtop's primary constraint is plan-based concurrency - the maximum number
  of simultaneous cloud browser sessions - rather than a published per-minute
  request quota. Each plan caps concurrent sessions (Free 3, Starter 3,
  Professional 30, Enterprise 100, Custom negotiated). Throughput is further
  governed by a monthly credit balance consumed per browser operation, and
  individual AI operations accept costThresholdCredits / timeThresholdSeconds
  guards to bound a single call. Specific HTTP request-per-minute limits are
  not published and are not reconciled in this artifact.
notes: >-
  Confirm any per-endpoint HTTP rate limits, concurrency burst behavior, and
  throttling response codes against Airtop documentation and account settings
  during reconciliation. Concurrency limits and credit pools are the
  effective governors of throughput.

responseCodes:
  throttled: 429
limits:
- name: Simultaneous Sessions
  scope: account
  metric: concurrent_sessions
  limit: plan-based (Free 3, Starter 3, Professional 30, Enterprise 100)
  notes: Maximum cloud browser sessions running at once; raises with plan tier.
- name: Monthly Credits
  scope: account
  metric: credits
  limit: plan-based credit pool
  notes: Credits consumed per page load, interaction, scrape, and AI query/extraction; complex actions (e.g. captcha) cost more.
- name: Per-Operation Cost Threshold
  scope: request
  metric: credits
  limit: caller-defined (costThresholdCredits)
  notes: Optional per-call guard that cancels an AI operation if it would exceed the credit budget.
- name: Per-Operation Time Threshold
  scope: request
  metric: seconds
  limit: caller-defined (timeThresholdSeconds)
  notes: Optional per-call guard that cancels an AI operation after the time limit.
policies:
- name: Concurrency-Based Limiting
  description: Throughput is governed mainly by simultaneous-session caps per plan rather than a fixed RPM quota.
- name: Credit Exhaustion
  description: When the monthly credit pool is depleted, further operations are blocked until credits are replenished or the plan is upgraded.
- name: Backoff Strategy
  description: Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
