# Getting Access

There are four ways to build with Saturday. One question routes you: where do your athletes live?

| Lane                 | Who                                                                | Athletes live in…        | Auth                          | Money                                                     |
| -------------------- | ------------------------------------------------------------------ | ------------------------ | ----------------------------- | --------------------------------------------------------- |
| Consumer app         | An athlete                                                         | the Saturday app         | app account                   | app subscription                                          |
| **Coach portal**     | A coach managing real Saturday-app athletes                        | **the Saturday app**     | portal login + `cp_` API keys | Pro Coach+ subscription (portal); `cp_` keys on Business+ |
| **Individual API**   | Dev-athletes, AI-assisted coaching businesses, team-scale builders | **your own system**      | self-serve `sk_` key          | \$5.39/month, no contract                                 |
| **Platform partner** | A platform embedding Saturday for its whole user base              | **the partner's system** | `sk_` key via agreement       | rev share + athlete subscribe loop                        |

## Individual API (self-serve)

You're building your own product, tooling, or coaching stack, and athletes live in **your** database.

* **Sign up:** [saturday.fit/api](https://saturday.fit/api). Enter an email, complete Stripe Checkout, and your key is revealed once on the success page and emailed to you. Programmatic path: `POST /v1/signup` (no auth) returns a hosted checkout URL, built for AI agents acquiring access for their humans.
* **Price:** \$5.39/month flat. Cancel anytime.
* **Trial economics:** every athlete you create gets the standard [30-day full-precision trial](/guides/freemium-model#30-day-full-precision-trial) (15 calls day one, then 5/day) automatically.
* **Limits:** 2 requests/second and 200 calls/day, counted per account rather than per key. Outgrowing them is when we want to hear from you: [support@saturday.fit](mailto:support@saturday.fit).

## Coach portal (your athletes use the Saturday app)

If you coach real Saturday-app athletes, the [coach portal](https://coach.saturday.fit) is your lane: roster, alerts, coverage. Your `cp_` API key lets you build scripts against your roster. See the [Coach API guide](/guides/coach-api).

## Platform partnership

You run a training platform and want Saturday embedded for your entire user base: partner-namespaced athletes, revenue share, [bundle and team offers](/guides/freemium-model#how-discounts-stack), webhooks at platform scale. That one starts as a conversation: [alex@saturdaymorning.fit](mailto:alex@saturdaymorning.fit).

<Note>
  A big team wanting both app athletes *and* custom tooling beyond roster scripts is partner-shaped. Start the conversation rather than stretching a self-serve key.

## Discovery for agents

`GET https://api.saturday.fit/v1/` (no auth) self-describes the API: the endpoints currently exposed, plan, price, trial shape, and both signup paths. Site context: [saturday.fit/llms.txt](https://saturday.fit/llms.txt).
