post/price-compare/v1/category2 credits

browse a comparison-site category by its id/slug → product cards (same shape as search). geizhals-only (cimri/akakce expose search/product/offers/price_history/suggest/compare).

Parameters

Geizhals category id or slug — the value after ?cat= (e.g. 'umtsover' for Handys, 'sm_ssd' for SSDs). Discover via the categories action.

Price-comparison source. LIVE: geizhals (DACH, full-curl SSR) · akakce (TR, BARE api6.akakce.com internal JSON API — no browser, curl_cffi+proxy) · cimri (TR, browser-mint over the Cloudflare managed-challenge). Idealo is NOT live: its /preisvergleich/* data prefix is behind Akamai Bot Manager (_abck sensor) which our proxy pool cannot clear (browser-mint attempted live 2026-06-11 — see notes/browser_mint_verdict.json; needs cleaner residential/mobile IPs).

Locale host. geizhals: de/at/eu (same DOM, different merchant pool). cimri/akakce are TR-only (country is ignored for them).

Result page (1-based). Page forward with meta.next_page. (1–50)

Result sort order. geizhals: passed to the site 'sort' value. akakce: engine-side offer sort — 'p' price asc, '-p' price desc.
