# Access tiers
> What Basic, Premium, and Full can read on the platform, the REST API, and MCP — including payments, key prefixes, and grain.
Ornn Data has three customer-facing plans. Trial is Premium with a 72-hour clock and no bill. Access is enforced on the REST API by the key prefix, on MCP by the account's own grant, and on the website by the live platform tier.
| Plan | Payment | API key | Grain | History |
| --------------------------- | ---------------------------------------------------------------------------- | ---------- | ---------------------------- | --------------------------------- |
| **Basic** | Free. No account. | None | Daily | Trailing window only |
| **Premium** (and **Trial**) | **\$500 / month**, self-serve on Stripe. Trial is 72 hours, granted by Ornn. | `sk_prem_` | **Daily only** | **Complete — no trailing window** |
| **Full** | Custom. Organization-grained, billed through Rillet. | `sk_live_` | Daily, hourly, and real-time | Complete, every grain |
A Premium key asking for `granularity=hourly` or `auto` is **served at daily**, not refused. Read the `granularity` and `access` fields on the response. The two endpoints that exist only to serve sub-daily data — `/api/gpu/{gpuName}/hourly` and `/api/gpu/{gpuName}/realtime` — return `403` for a Premium key.
Compare plans on the website at [data.ornn.com/pricing](https://data.ornn.com/pricing). Field-level coverage is in the [data dictionary](/docs/data-dictionary). A gating or billing change must update both pages and the internal Word file (`backend/tests/data-dictionary-gating.test.js`).

### Public GPU window (Basic)
`H100 SXM` · `H200` · `B200` · `A100 SXM4` · `RTX 5090`
`RTX PRO 6000 WS` is Premium and Full only.
### Public OTPI window (Basic)
`anthropic` · `openai` · `google` · `deepseek`
The other seven labs — `minimax`, `xiaomi`, `qwen`, `moonshotai`, `z-ai`, `mistralai`, `meta-llama` — are Premium and Full only.
## API keys
Keys are created in [Settings → API Keys](https://data.ornn.com/settings?tab=api-keys). The prefix **is** the tier: the backend identifies a key from the secret itself, not from the owner's current database row.
| Who can mint | Prefix | What it unlocks |
| ------------------------------------------------------------------------------ | ---------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Own **trial** or **premium** grant | `sk_prem_` | Every index family at daily grain, all-time. Forward curve. Memory, coding, workload, volume, frontier, power, buyers. **Not** hourly, real-time, or neocloud. |
| Own **full** grant, or membership in a **Full** organization with no own grant | `sk_live_` | Unrestricted. Floor-dependent Full keys are revoked if the organization ceiling drops. |
| Basic, or a trial/premium organization floor with no own grant | — | Cannot mint. |
A `sk_prem_` key is Premium even if the permissions stamp is missing or the owner is later upgraded. A `sk_live_` key minted before Premium existed stays Full. Downgrading an account revokes its keys; mint again on the new tier.
See [Manage API keys](/docs/manage-api-keys) and [Authentication](/docs/authentication).
## Payments
* **Basic** — no invoice.
* **Trial** — no invoice. 72 hours, starting on first visit. Request from [data.ornn.com/pricing](https://data.ornn.com/pricing) or [data@ornn.com](mailto:data@ornn.com). The clock is the cost.
* **Premium** — \$500 per month, server-pinned. Self-serve: Settings → Billing, or the subscribe button on `/pricing`. A saved card is charged automatically; otherwise Stripe emails a hosted invoice. Cancel by writing to [data@ornn.com](mailto:data@ornn.com). Bound by the [Premium Data Use Addendum](https://data.ornn.com/premium-data-use).
* **Full** — custom, organization-grained, billed through Rillet. Talk to [data@ornn.com](mailto:data@ornn.com).
## MCP
Access follows the same ladder. Paid tools need an **own** grant: a Full organization floor covers the product, not the unscoped MCP service key.
| Account | Tools |
| ---------------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| Signed in, no paid grant | Public tools, shaped to the Basic window |
| Trial or Premium (own grant) | Paid index-family tools, **daily grain**, complete daily history. Neocloud tools and `get_gpu_price_at` are not included |
| Full (own grant) | Every tool, full depth |
| API key (`sk_prem_` or `sk_live_`) | Same as that key on the REST API |
See [Ornn MCP](/docs/mcp-server).
## Rate limits
Public Basic and catalog routes that use the public limiter are **60 requests / minute / IP**. Sending a key does not replace that limiter. See [Rate limits](/docs/rate-limits).
