Monthly plans

A fixed monthly price for a number of credits, used in 5-hour, weekly and monthly windows.

Requests to the models a plan covers use its credits instead of your balance. One plan covers every API key on your account and works with any OpenAI-compatible tool.

Plans

Plan	Price	First month	Credits a month	Per 5 hours	Per week	Requests a minute
$10 plan `plan10`	$10 / month	$5	1,000	200	500	60
$25 plan `plan25`	$25 / month	$12.50	2,750	550	1,375	120
$50 plan `plan50`	$50 / month	$25	5,500	1,100	2,750	240

Plans cover GLM-5.3, GLM-5.3-Flash and DeepSeek V4.1 Flash. Other models bill your balance. Model ids: glm-5.3-flash, glm-5.3, deepseek-v4.1-flash.

What a request uses

Credits for its input, cached input and output tokens, at that model's rates. The rates follow the market and can change at any time.
A request that fails before any output uses nothing.
The Usage page in the dashboard shows the credits each request used.
Over the requests-a-minute limit: 429 rate_limit_exceeded. Wait for Retry-After.

How far credits go

Plan	GLM-5.3-Flash, requests a month	GLM-5.3, requests a month	DeepSeek V4.1 Flash, requests a month
$10 plan	about 130,000	about 4,500	about 710,000
$25 plan	about 360,000	about 12,000	about 1,900,000
$50 plan	about 730,000	about 24,000	about 3,900,000

Each figure is for one model alone: typical coding-agent requests; actual usage varies. Updated hourly. The $10 plan is about 4× OpenCode Go.

Limits and resets

Window	Limit	Resets
`5h`	20% of the month's credits	5 hours after your first request in it
`week`	50%	Every 7 days from when your plan started
`month`	100%	At the end of the paid period

A request goes through when every window has room. Its credits count in full, even past a limit; the next request then waits for the reset. Unused credits don't carry over.

When you reach a limit

The request gets HTTP 429 with code plan_limit, and nothing is charged. Retry-After is the seconds until the window resets.

HTTP

HTTP/2 429
retry-after: 7800
x-caft-plan-limit: 5h

  }
}

To keep going at normal prices, turn on Use balance when the plan limit is reached under Billing in the dashboard. It is off by default.

Buying a plan

Under Billing in the dashboard:

By card: renews monthly until you cancel.
From your balance: 30 days. Auto-renew from balance renews it if your balance covers the price.
With x402 (agents and wallet accounts): POST https://caft.dev/api/x402/plan?tier=plan10, paid like an x402 top-up. 30 days, no renewal.

The first month is half price, once per person, by card or from the balance. It needs a verified email address: a wallet-opened account without one doesn't get it, and neither does a purchase through x402. It is also once per card: a discounted plan paid with a card that already had it on another account is cancelled and refunded in full, and you can buy it again at the full price.

Changing or cancelling

Upgrade: starts at once. The unused part of the old plan is credited to your balance: the price × (1 − the larger of the period used and the credits used).
Downgrade: takes effect at the next renewal.
Cancel a card plan under Billing → Manage. It runs to the end of the period you paid for.
A failed card renewal keeps the plan working for 1 day while it is retried. When a plan ends, your keys bill your balance.
No refunds for part of a period. See section 5 of the Terms.

Fair use

A plan is for one person's own use, with any number of keys and tools. Don't share it or resell access to it.
