A new key comes with a 100 JPY welcome credit (1,000 GPU-seconds) that lasts 14 days and covers previews and finals. Saving a card on a page that charges nothing adds 400 JPY more, once per card. After it is used up or expires, previews are free up to 2 GPU-minutes per key per day and final renders cost 0.1 JPY per GPU-second (6 JPY per GPU-minute) from prepaid credit.

MCP server: https://render.janction.jp/mcp. No sign-up. A welcome credit of up to 500 JPY for a new key (100 JPY with no card, 400 JPY more after saving a card that is not charged). Every other app: /blender-mcp.

| Amount | 100 JPY (1,000 GPU-seconds) per new key, for previews and finals |
|---|---|
| Lasts | 14 days from key creation. The balance and expiry are in GET /v1/me under quota.welcome (MCP: billing) |
| One per network | One full welcome credit per network every 30 days; further keys from the same network use what is left of that network's credit |
| First top-up | The first top-up during the 14 days counts 1.5x, with the bonus capped at 500 JPY (100 JPY buys 150 JPY of credit); not combined with the volume bonus, the larger applies |
| Sign-up | None. POST /v1/keys returns a key; MCP clients get one through the OAuth consent page. No card for the first 100 JPY of the welcome credit |
| Saving a card | Saving a card on a Stripe page that charges nothing adds 400 JPY once per card (prepaid cards do not qualify). Offered only when the cardless credit is used up (card_offer on the 402, GET /v1/me and the MCP billing reply) |
Rendering bigger Blender files? Free keys send .blend files up to 1GB; paying 500 JPY or more in total opens .blend files up to 5GB, and your input files and render results are kept for 7 days instead of 24 hours. Saving a card alone does not unlock 5GB; it applies after an actual payment.
| Free | Paid | |
|---|---|---|
| .blend upload | up to 1GB | up to 5GB |
| Other 3D files (GLB, FBX, USD and others) | up to 512MB on both | |
| Data kept | 24 hours after last use | normally up to 7 days after last use |
| Storage | up to 20GB per key in total (the input scenes still kept; assets have their own limit, render results are not counted) | |
| Rendering | free credit and free daily previews | metered at 0.1 JPY per GPU-second |
| Start | no sign-up | pay 500 JPY or more in total (make a key at /start first; the Starter and Pro monthly plans and USDC count the same) |
A paid key is one that has paid 500 JPY or more in total (top-ups, auto top-up, monthly plans, USDC; the free credit, the card-saving credit and bonuses do not count). Once paid, a key keeps 5GB uploads and 7-day keeping even when its balance reaches 0. After a full refund or a chargeback, new use is treated as free; data already kept stays until the expiry it had then.
Data of paid users is normally kept for up to 7 days after last use. It may be kept for less when the operation requires it, for example when server storage runs short. Keep a copy of anything important.
The temporary link for a file left at /upload is separate from this: 12 hours. Download links for results last about 24 hours and can be renewed while the data is kept.
Start from your problem: what is really free · render without a GPU · cloud rendering, step by step
| Previews | Free up to 2 GPU-minutes (120 GPU-seconds) per key per day, reset at 00:00 UTC (09:00 JST); beyond that, the same price as finals |
|---|---|
| Finals | 0.1 JPY per GPU-second (6 JPY per GPU-minute). A GPU-second is worker time including Blender start-up and scene load |
| Examples | 4-frame preview (about 4 GPU s) ≈ 0.4 JPY; 24-frame 720p MP4 (about 60 GPU s) ≈ 6 JPY; one 1080p frame at 128 samples (about 11 GPU s) ≈ 1.1 JPY (benchmarks). Each of these is 0 JPY while the welcome credit lasts |
| Per final render | Up to 3,000 frames per instruction (run as parts of 240 under one job id); 1080p per frame on free time, up to 4K (3840x2160) on prepaid credit; at most 10 GPU-hours per job (oversized jobs get 400 beta_limit) |
| Credit | Prepaid credit bought by card at a Stripe Checkout page (from 100 JPY in steps of 100 JPY). A job reserves 1.5x its estimate as a ceiling, is settled at the actual GPU seconds and the difference is released |
|---|---|
| Failed jobs | Only the finished part counts. The unfinished part is not counted up to 5 minutes per key per day; failures on JANCTION's side never count |
| Without enough credit | HTTP 402 payment_required with checkout_url (the top-up page) and how much of the job the free time covers |
| Quote first | render_estimate / POST /v1/estimate returns GPU seconds, a wall-clock estimate, the free time left, the amount that would be charged (cost.estimated_yen), the currency and an expiry, so an agent can state the cost before running |
| Spend caps | By default 3,000 JPY per job (one render request) and 10,000 JPY per key per day. The cap set for a render request applies to the whole request, however the service splits it internally; change them with POST /v1/me/limits |
| Auto top-up | With a saved card, 2,000 JPY (2,200 JPY of credit) is added when the balance drops below 200 JPY. The amount, the threshold and the monthly cap can be changed (by default at most 10,000 JPY a month and 3 times a day). A job that would run short is topped up on the spot instead of stopping. Turn it on or off with POST /v1/billing/autocharge and POST /v1/billing/autocharge/off; over MCP, with the links billing returns |
| Monthly plans | Starter: 2,980 JPY a month adds 3,500 JPY of credit; Pro: 9,800 JPY a month adds 12,000 JPY of credit (a monthly top-up). Unused credit carries over and the price per GPU-second is the same. Cancel anytime; it runs to the end of the paid month. Subscribe with POST /v1/billing/subscribe; list: GET /v1/billing/plans |

| You pay | Credit you get | If it is your first top-up in the welcome period | About |
|---|---|---|---|
| 100 JPY | 100 JPY | 150 JPY | 0.3 GPU-hours |
| 500 JPY | 500 JPY | 750 JPY | 1.4 GPU-hours |
| 2,000 JPY | 2,200 JPY (incl. a 200 JPY bonus) | 2,500 JPY | 6.1 GPU-hours |
| 5,000 JPY | 5,750 JPY (incl. a 750 JPY bonus) | 5,750 JPY | 16.0 GPU-hours |
| 10,000 JPY | 12,000 JPY (incl. a 2,000 JPY bonus) | 12,000 JPY | 33.3 GPU-hours |
Larger top-ups get a bonus (10% from 2,000 JPY, 15% from 5,000 JPY, 20% from 10,000 JPY). The first top-up in the 14-day welcome period counts 1.5x, with the bonus capped at 500 JPY; it is not combined with the volume bonus, the larger applies. Any amount from 100 JPY can be paid. Bonus credit is not refundable in cash and is withdrawn in proportion if a top-up is refunded.
