Kline0 will have its own SDK and API layer. This is important because Kline0 is not only a trading app. It is also becoming an infrastructure layer for trading campaigns, exchange integrations, creator workflows, AI agents, and partner reporting.

## API categories

| API category             | Purpose                                                                  |
| ------------------------ | ------------------------------------------------------------------------ |
| Campaign API             | Create, manage, and monitor trading competitions.                        |
| Leaderboard API          | Read rankings, scores, eligibility, and campaign results.                |
| Exchange Integration API | Connect venue-level data and execution where approved.                   |
| Creator API              | Track creator contribution, campaign content, and referral activity.     |
| AI Agent API             | Access structured AI outputs for trade, campaign, and creator workflows. |
| Webhook API              | Notify partners about campaign, leaderboard, and activity events.        |

## Example endpoints

```
POST /api/v1/campaigns
GET  /api/v1/campaigns/:id
POST /api/v1/campaigns/:id/join
GET  /api/v1/campaigns/:id/leaderboard

## SDK phases

Kline0 SDK development can happen in phases:

| Phase        | Scope                                                                    |
| ------------ | ------------------------------------------------------------------------ |
| SDK Alpha    | Internal partner tooling and campaign dashboard support.                 |
| SDK Beta     | Selected projects and exchanges access campaign and leaderboard tools.   |
| Public SDK   | Developer-friendly package for approved integrations.                    |
| Advanced SDK | Webhooks, analytics exports, AI agent endpoints, and partner automation. |

## SDK design principles

* Clear permissions
* Scoped API keys
* Rate limits
* Webhook signatures
* Audit logs
* Sandbox testing
* Developer documentation
* Secure partner onboarding

## Strategic value

The SDK/API layer allows Kline0 to scale beyond its own app interface. It gives exchanges, projects, creators, and partners a path to build on top of Kline0 infrastructure.
