**TMX/TSX** company-directory search (`tsx.com/json/company-directory`): **fully open**. No UA requirement (byte-identical with no UA header at all), no cookie, no auth, clean 200s including a self-describing empty-result shape (`"isHttpError":false` next to `results:[]`). This contradicted this lane's own working assumption that TMX would be a refusal case — it was not. - **NSE India** (`nseindia.com/api/marketStatus`): blocks at the **connection layer** — a descriptive, non-browser-looking User-Agent string gets an HTTP/2 stream reset with **no status code at all** (`curl: (92)`, reproduced 4/4), while the identical request with a generic desktop Chrome UA string and **zero cookies** succeeds every time (4/4). The common belief that NSE requires a prior homepage-cookie handshake was tested directly and found unnecessary; the actual gate is UA-string content, checked before any cookie logic. - **HKEX** (`www1.hkex.com.hk/hkexwidget`): a **bot-management WAF** (Akamai-shaped `TS0...` cookies, Tomcat "Error report" 403) that rejects every plain-HTTP request uniformly — a real, valid symbol and a nonexistent one get the identical 403, so the gate fires before the application's own symbol validation ever runs, and a same-site `Referer` header makes no difference. - **BSE India** (`api.bseindia.com`): a **uniform WAF 403** ("Access Denied", Apache-module-shaped, unique `Reference #` per hit) that held constant across three header combinations including a full desktop browser UA with matching `Origin`/`Referer` — unlike NSE, changing the declared UA does not get a client through. Net: "non-US exchange, public data" spans the full range from zero gate (TMX) through a fingerprint-on-one-header block (NSE) to two different flavors of uniform WAF block that no amount of header-tuning gets past in a plain HTTP client (HKEX, BSE) — there is no single mitigation that works across this cluster.
