Quelles sources publiques nous lisons — et lesquelles nous refusons

Une source n’alimente un rapport qu’à deux conditions : son verdict de licence est exploitable, et un connecteur existe. Un verdict rouge est une source que nous refusons, pas une source qui nous manque — et aucun chiffre d’aucun rapport ne vient d’ailleurs que de cette liste.

Vert — Gratuite, autorisée ou API officielle — lue librement.
Orange — Autorisée mais payante, limitée en débit ou sous clé — ouverte par une clé payante.
Rouge — Conditions qui l’interdisent, ou tarif réservé aux grands comptes — refusée ; aucun connecteur n’est jamais branché.

Demande — signal communautaire

Wikimedia Pageviews Résolution jusqu’à pays	Vert	Gratuit free (no key; UA required)	Non branchée	Free, keyless and language-partitioned (a real FR/ES parity lever) — and it measures encyclopedic ATTENTION, not commercial intent. Scoped 2026-08-06 as the keyless way to lift the hard-demand confidence cap, then refused: at the time the completeness check counted calls and not kinds, so wiring it into the probe scope would have raised confidence 0.5→0.7 on a measurement of the wrong thing, invisibly. That hole is now closed at the runtime (only intent measurements count toward the cap), so the cap no longer depends on this refusal holding — but the refusal stands on its own merits. Wire it as EVIDENCE (a topic-attention reading rendered as such) if wired at all; never as an intent provider (the intent-provider list is the only thing that lifts the cap).
DataForSEO (search intent / Trends) Résolution jusqu’à ville	Orange	Payant PAYG	Lue aujourd’hui	Search-intent + keyword volume; floors at city (no sub-city volume).
Discourse public JSON (per-forum allow-list) Résolution jusqu’à monde entier	Orange	Clé requise free (per-forum rate limits; API key optional/per-forum)	Non branchée	G1 2026-08-06: software surface is sanctioned JSON; each forum's ToS is the real gate. G5 verified reachability of several public /search.json endpoints but found no host whose terms affirmatively permit automated commercial retrieval of post text — the allow-list is therefore empty. Never unsolicited multi-forum crawl. Wire only allow-listed instances, each as its own row marked built.
Forum threads via Google (DataForSEO SERP) Résolution jusqu’à pays	Orange	Payant PAYG	Non branchée	The discussion threads Google itself lists for a query, read through the same paid search-data provider as the search-volume probe: titles, hosts and post counts of Reddit, Nextdoor, Quora and trade-forum threads, never the posts' text. Not wired yet: the connector is a named lot; until it lands, a local-service idea reads only the search-volume probe and the Stack Exchange room of its trade, and refuses honestly when those are silent.
YouTube Data API v3 Résolution jusqu’à monde entier	Orange	Clé requise free (10k quota units/day; search.list costs 100 each)	Non branchée	Built as G3 (PR #21) and refused on 2026-08-06 — not on the licence, which is workable, but on two clauses our pipeline cannot satisfy today. API ToS III.E.4.h: a developer must not 'use the YouTube API Services to create derived scores or metrics' — the demand score IS one, and the scoring step has no per-source exclusion path, so a YouTube signal's engagement reaches the score through the engagement term and its text through the pain blend. III.E.4.d requires stored API data to be refreshed or deleted within 30 days — incompatible with a buyer's permanent report and with frozen replay corpora holding full signal text in git. Quota makes it scarce too (one 100-unit search.list per keyword ⇒ ~100 keywords/day for a whole deployment), but scarcity is not why it is refused. Wire only behind a context-only path that keeps a source out of every scored quantity, plus a real retention mechanism. Until then the content-creator idea class has no community source, and the report says so rather than implying one.

Commerce — lecture des marketplaces

Source	Verdict	Coût	État	Pourquoi
eBay (Browse API) Résolution jusqu’à pays	Vert	Clé requise free dev account	Lue aujourd’hui	itemCount + price band. Browse API needs an OAuth token minted from App ID + Cert ID (client secret) — not App ID alone.
Etsy Résolution jusqu’à monde entier	Vert	Clé requise	Lue aujourd’hui	Free niche demand; Etsy Open API v3 public read needs an x-api-key keystring (OAuth only for private/write).
Amazon (Keepa + Rainforest) Résolution jusqu’à pays	Orange	Payant Keepa €19/mo base + €49/mo API · Rainforest from $23/mo (500 req, free trial; $375/mo = 250k)	Lue aujourd’hui	BSR = demand, price history = price-band fit, reviews = buyer pain. Keepa needs the €19/mo base sub on top of the API tier.
Google Shopping via DataForSEO Résolution jusqu’à ville	Orange	Payant PAYG	Lue aujourd’hui	Rewritten 2026-09-10: the endpoint wired 2026-08-03 was dead on arrival. Now DataForSEO's asynchronous Merchant API, queued and polled until ready. Zero new credentials (reuses the demand probe's pair). Offline-tested on a captured real fixture; endpoint to fully live-verify like every connector except eBay.
Store Leads (Shopify technographics) Résolution jusqu’à pays	Orange	Payant paid (~$250/mo Pro tier for API)	Lue aujourd’hui	Store-count by niche/geo = market sizing. The compliant Shopify answer. API access is the Pro tier, not entry-level.
Apple App Store customer-reviews RSS	Rouge	—	Refusée	Keyless and it answers 200, which is exactly the trap. Apple Media Services Terms: a user 'may not use any software, device, automated process … to scrape, copy, or perform measurement, analysis, or monitoring of, any portion of the Content or Services' — measurement is the one word that names what a demand read does. Researched 2026-08-06 (G1 source 4); liveness is not a licence. Filed under commerce, next to the Shopify App-Store row, because it is a store surface, though the use we wanted was demand-side review-pain for the mobile-app idea class. No free legal twin exists: both stores keep competitive review APIs owner-only and the third parties are paid resellers, so that class gets Stack Exchange plus search intent, and is told review-pain is absent rather than left to assume it was covered.
Shopify App-Store scrape	Rouge	—	Refusée	ToS-hostile + Cloudflare-blocked. Use Store Leads instead.
