From a38d1a789e146460d7c9506d4cc907c93eef6d82 Mon Sep 17 00:00:00 2001 From: Keunwoo Choi Date: Sat, 12 Sep 2026 21:34:31 -0400 Subject: [PATCH 1/4] fix: bring web feed headers current; loud feed errors; numeric feed endpoint Instagram now login-walls the /api/v1/feed/user/ endpoint and rejects the browser identity ensta sent (Chrome 119 UA with sec-ch-ua set to the full UA string, a random x-ig-www-claim, and 2023-era x-asbd-id). Even a valid logged-in session was redirected to the login page. - New ensta/lib/WebHeaders.py: single source for UA, matching sec-ch-ua* client hints, x-ig-app-id and x-asbd-id, plus an api_headers() builder. - Guest/WebSession/Authentication use it instead of hand-copied headers. - x-ig-www-claim starts at "0" and is updated from the x-ig-set-www-claim response header (WebSession installs a response hook), instead of a random "hmac." value. - x-csrftoken is read from the cookie jar at request time so it matches the csrftoken cookie Instagram set. - posts(): optional user_id= selects the numeric feed endpoint the web app itself calls; redirects are no longer followed and are reported as a login wall; 401/require_login, non-JSON and unexpected bodies now include HTTP status, URL and a body snippet in the exception message. - Tests for the feed request shape and error reporting.

The web app fetches the profile timeline through POST /graphql/query with the persisted PolarisProfilePostsQuery doc_id, and that still works for logged-in sessions, so WebSession.posts() now does the same. The request is deliberately minimal (variables, doc_id, server_timestamps; x-ig-app-id, x-csrftoken, referer): adding the web app's own request markers without its per-page LSD/DTSG tokens makes Instagram answer with the HTML app shell instead of JSON. The response nodes have the v1 media shape, so the existing post parser is reused. Pagination follows page_info.end_cursor. Session cookies are now set with domain=.instagram.com. Set without a domain they lingered next to the fresh domain-scoped cookies Instagram sends back, and every request carried duplicate sessionid/csrftoken/rur/ ds_user_id/ig_did cookies.
