Pricing & Billing

OpenDunes billing is prepaid and denominated entirely in Algerian Dinars (DA). No subscription, no foreign card, no USD conversion on your end.

How it works#

1. You deposit DA into your OpenDunes account via SATIM.
2. Your balance is credited 1:1 — deposit 1,000 DA, get 1,000 DA of balance.
3. Each API request deducts from your balance based on what the model processed, in that surface's unit.
4. When your balance reaches zero, requests return 402 insufficient_credits until you top up.

Depositing DA#

Deposits go through SATIM — Algeria's national interbank payment network. Two card types are accepted:

• CIB — issued by any Algerian bank
• Edahabia — Algeria Post (Algérie Poste)

Go to Dashboard → Billing to initiate a deposit. There is no minimum deposit amount. Your balance is credited at face value — what you deposit is what you can spend.

The price you see is the price you pay#

Every model's DA price is published in the catalog, per surface unit. That published price is the final price — there are no per-request fees, no deposit fees, and no currency conversion on your end. Deposits are credited 1:1 and usage is billed at the catalog DA price. Nothing else is added.

Exact-integer money#

Internally, all balances and costs are tracked as bigint micro-DA (one-millionth of a Dinar). Money is never represented as a float, so fractions of a Dinar are exact and there are no rounding surprises on your balance. Per-request costs are computed in micro-DA and rounded up to the smallest unit, with a floor of one micro-DA per billable request.

Per-surface pricing#

Each model surface is billed in its own unit. The catalog reports the DA price in that unit, and your usage is metered the same way.

Text cost#

cost = (input_tokens × input_rate) + (output_tokens × output_rate)

Rates are DA per million tokens. Example: a model priced at 12.40 DA/M input and 49.60 DA/M output. A request with 500 input and 200 output tokens:

• Input: 500 / 1,000,000 × 12.40 DA = 0.0062 DA
• Output: 200 / 1,000,000 × 49.60 DA = 0.00992 DA
• Total: ~0.0162 DA

Unit-surface cost#

Image, speech, transcription, video, and rerank are billed by quantity:

cost = quantity × unit_price

For example, an image model at 6.00 DA/image generating n: 2 costs 12.00 DA; a transcription model at 0.04 DA/second on a 30-second clip costs 1.20 DA (audio seconds are rounded up). Video generation reserves the cost of the requested duration up front and settles on completion — a failed or timed-out job releases the full hold and charges nothing.

Checking your balance#

Your balance is returned on every API response in the X-Balance-Available response header, expressed in micro-DA:

X-Balance-Available: 9234500

You can also view your balance, transaction history, and per-model usage breakdown in Dashboard → Billing.

Billing and Law 18-07#

All billing metadata (token counts, model slug, timestamps, costs) is retained for audit purposes under Algeria Law 18-07. Request and response content is passed through a PII redaction pipeline before any logging — personal data is not stored in billing records.
