Your organization runs on a plan that sets two allowances: how many tokens you can use per billing period, and how many sessions you can run at the same time. Usage is tracked per organization, both allowances are readable from the API at any time, and there are no request-rate limits.

Need more than Developer offers? Enterprise plans with higher allowances are available. Contact us at support@hcompany.ai. Token and concurrency allowances are subject to change, so read the live values from the API (below) rather than hard-coding the numbers in your integration.

​
Token usage

Tokens are consumed by the model as your agents run, and they accrue against your plan’s per-period allowance. The allowance resets at the start of each billing period: for Free plans on your signup day-of-month, and for Developer plans on your subscription’s renewal date. When the allowance runs out, creating a session (or messaging a finished one, which restarts it) fails with 402 Payment Required. The error’s detail carries your limit, used, and the window_end when the budget resets; see Errors. Check your current token usage with GET /api/v2/quota/tokens: 
curl https://agp.eu.hcompany.ai/api/v2/quota/tokens \
  -H "Authorization: Bearer $HAI_API_KEY"
Response

  "limit": 15000000,

  "remaining": 10800000,

FieldTypeDescription
limitinteger | nullTokens allowed this period. null means unlimited.
usedinteger | nullTokens used so far this period. null if the usage figure is momentarily unavailable.
remaininginteger | nullTokens left (max(limit - used, 0)).
window_startstringStart of the current billing period (UTC).
window_endstring | nullEnd of the current billing period (UTC).

​
Concurrent sessions

Separately from tokens, your plan caps how many sessions can run at once. A session holds a slot while it is in a non-terminal state (pending, running, awaiting_tool_results, paused, or idle) and frees it as soon as it reaches a terminal state, including when you cancel it. queued sessions hold no slot and never count against your quota. GET /api/v2/sessions/quota returns your current concurrency usage: 
curl https://agp.eu.hcompany.ai/api/v2/sessions/quota \
  -H "Authorization: Bearer $HAI_API_KEY"
Response
{
  "scope": "user",
  "limit": 10,
  "active": 3,
  "available": 7
}
See Get quota for the field-by-field reference. Creating a session while at your limit doesn’t fail: the create is accepted with status queued and the session starts automatically when a slot frees up. If you prefer an immediate error, set queue: false on the create body to get a 429 Too Many Requests instead; the SDKs retry 429 with backoff automatically, see Errors.

​
Managing your subscription

Start a Developer subscription from the billing page in the platform dashboard; checkout is card-only. Manage your card and download invoices through the Stripe billing portal, linked from the same page. Cancelling stops the renewal: your Developer allowances stay active until the end of the current billing period, after which the organization reverts to the Free plan.
