# Latest RSI datapoint

`GET /ta/{slug}/rsi/latest`

## Request

- Base URL: `https://rest.coincap.io/v3`
- URL: `https://rest.coincap.io/v3/ta/{slug}/rsi/latest`
- Auth: one of:
  - HTTP bearer
  - API key in query parameter `apiKey`
- TypeScript: <https://skmtc.dev/coincap/apis/coincap-api/docs/ta/:slug/rsi/latest/get.ts> (a function with typed inputs; its response is checked against the schema)

LEGACY — prefer /agentFriendly/ta/{slug}/rsi (agent-optimized output) or /ta/{slug}/allLatest for all indicators at once. Use this legacy endpoint only when you need a custom start/end range or non-default periods — the agentFriendly variant computes a fixed recent window.

## Path parameters

- `slug` string, required

## Query parameters

- `start` integer
- `end` integer
- `period` integer
- `smoothing` 'WSMA' | 'EMA' | 'SMA' | 'WMA'
- `fetchInterval` 'm1' | 'm5' | 'm15' | 'm30' | 'h1' | 'h2' | 'h6' | 'h12' | 'd1'
- `includeOriginal` string

## Response `200`
