# Fron Research Agent API

Fron Research (fronresearch.com) measures demand at recreation venues from inferred booking signals observed in public data: sell-through computed, revenue modeled with a P10–P90 range. This API answers questions from the public pages of Fron Research and its five Check sites and serves each site's free example day as rows. It returns passages with their canonical URLs, not a written answer: answer.instruction says how to use them, and followUp.questions are optional questions whose answers go in intent on the next search. Each site also serves this API at its own /api/agent, scoped to that site.

## How to ask

- Describe: `GET https://fronresearch.com/api/agent`
- Ask: `GET https://fronresearch.com/api/agent?q=how+does+HeatCheck+measure+sauna+utilization`
- Read a page: `GET https://fronresearch.com/api/agent?doc=heatcheck/pricing`
- Sample rows: `GET https://fronresearch.com/api/agent?doc=sample/heatcheck&format=json`
- JSON search: `POST https://fronresearch.com/api/agent {"query": "...", "intent": "...", "site": "lanecheck", "maxResults": 5}`
- MCP: POST https://fronresearch.com/api/agent with JSON-RPC 2.0 (MCP streamable HTTP, stateless). Tools: about, search, fetch.
- Contact us: `POST https://fronresearch.com/api/agent {"mode": "contact", "message": "...", "email": "optional"}`

Parameters: `q` question, 1–500 characters; `intent` optional, up to 300 characters: why you are asking and for whom (e.g. "sizing the NYC sauna market for an investor memo"). It does not change the results; it tells us which data to publish next; `doc` document id from a search result or the list below; `site` limit search to one site: heatcheck, lanecheck, parkcheck, baycheck, courtcheck, fronresearch (default: every site); `max` results, 1–10 (default 5); `offset` continue a long document from nextOffset; `format` md (default) or json; Accept: application/json also selects JSON.
