redfin-fpx

Redfin via fpx (no MCP)

Redfin fronts www.redfin.com — including every /stingray/... JSON endpoint — with an AWS WAF challenge that blocks plain curl/Node requests regardless of headers. fpx routes the request through the user's own signed-in browser tab (the Transporter extension), which has already cleared the challenge, so the same request succeeds. Most reads are anonymous (no Redfin login needed — just an open tab); the saved-homes and saved-searches endpoints additionally require the tab to be signed in to redfin.com.

This is the same data the redfin_* MCP tools return, reached with one CLI call instead of a running server. Every call rides through the bridge (no bootstrap-then-direct-fetch shortcut) — Redfin validates each request at the session level.

One-time setup

npm install -g @fetchproxy/cli              # provides `fpx`
fpx profile add redfin --domain redfin.com  # only the fetch capability is needed
fpx pair -p redfin                          # prints a pair code → approve in Transporter

Requirements: the Transporter browser extension installed, with an open www.redfin.com tab, and its Chrome Site access allowing redfin.com. Pairing persists — after the first approval every later fpx call reuses it.

Core call

Almost every endpoint is a GET to a /stingray/... path. Redfin prefixes every stingray JSON body with a literal anti-CSRF {}&&, so strip that before piping to jq:

fpx get 'https://www.redfin.com/stingray/api/gis?...' -p redfin \
  | sed -E 's/^\{\}&&//' \
  | jq '.payload.homes'

Every stripped body is an envelope { version, errorMessage, resultCode, payload } — check resultCode == 0 before trusting payload (a nonzero code means Redfin rejected the request; errorMessage explains why).

Ready-to-run request paths (autocomplete, search, property detail, price history, market trends, comparable rentals, climate risk, saved homes) are in references/stingray-endpoints.md. Exhaustive field lists live in the repo at src/tools/*.ts — the endpoints here are compact, live-verified subsets.
