# Bucketed market-wide net call premium / net put premium time series

`GET /v1/market/tide`

## Request

- Base URL: `https://flow-api.skylit.ai`
- URL: `https://flow-api.skylit.ai/v1/market/tide`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/skylit/apis/flowseeker-skylit-public-api/docs/v1/market/tide/get.ts> (a function with typed inputs; its response is checked against the schema)

Returns the market-wide intraday "tide" — bucketed Net Call
Premium and Net Put Premium series with both per-bucket and
cumulative values, plus an SPY price overlay for context. Two
directional flavors are emitted per bar: the standard `ncp`/`npp`
(call-buying minus call-selling, etc.) and a `manualNcp`/
`manualNpp` variant with the script-trade exclusion logic
relaxed for callers that need raw flow.
