Opedd — Licensed Content for AI

Issue a signed JWT attesting to EU AI Act Article 53 compliance for a specific license via GET /eu-ai-act/article-53-attestation (Phase 12 Wave 1 W1.4). Returns a freshly-signed HS256 JWT regulators can verify offline against the canonical signing key. Embeds: license context, usage-count over the attestation window, the most-recent Tempo Merkle root, and canonical claims (iss/sub/iat/exp/jti/aud). **The artifact AI labs hand to legal/procurement for EU AI Act Article 53(1)(d) transparency-obligation evidence.** Per INVARIANTS.md W1.6: this attests to EU AI Act Article 53 ONLY (buyer-side GPAI-model-provider transparency obligation). It does NOT discharge a publisher's CDSM Article 4(3) reservation obligation — that lives on the rsl_get tool (jsonld=true variant). Never conflate. Optional `content_id` scopes the attestation to one article; default is license-wide. Window cap: 365 days. Requires OPEDD_BUYER_JWT.

Browse the public Opedd license registry. Returns recently issued licenses and licensable content. Filter by publisher_id to explore all content from a specific publisher. Filter by article_id to see all licenses issued for a specific article.

Detect the content platform behind a URL via POST /detect-platform (Phase 12 Wave 3 W3.1). Public no-auth lookup. Given a URL, identifies what platform powers it (Substack / Beehiiv / Ghost / Medium / Brevo / custom) and returns the suggested onboarding workflow. Hostname-detectable platforms (Substack subdomain, Beehiiv suffix, etc.) resolve in milliseconds; custom domains may take ~few seconds while the detector probes well-known platform endpoints in parallel. Returns: {platform, confidence, archive_method, forward_method, required_credentials, instructions}. The archive_method + forward_method fields are the two onboarding-workflow inputs Opedd's setup wizard reads (one for historical content backfill, one for new-content forward stream). instructions is human-readable operator copy explaining the inferred path.

Browse per-event audit rows for the authenticated buyer via GET /buyer-audit (Phase 9.x). Each row carries license_terms + Tempo on-chain attestation (merkle_root + inclusion_proof when blockchain_status='confirmed'). Optional filter by event_type ('content_access', 'bulk_content_access', 'compliance_report_generated'). Window cap 30 days (vs 90-day cap on get_compliance_dossier). Attestation inclusion proof is included on every row by default — no separate flag needed (M6.4 consolidation per founder ratification: tools 4 + 6 merged into one cleaner mental model). Requires OPEDD_BUYER_JWT (Supabase session JWT from the buyer portal).

Fetch the authenticated buyer's account profile + masked API key list via GET /buyer-account. Returns the enterprise_buyers row (contact_email, buyer_org, created_at, etc.) plus a list of all buyer-side API keys with masked prefixes (NEVER plaintext post-issuance — only the 12-char key_prefix is returned, e.g. 'opedd_buyer_'). Use cases: post-signup verification ('what was just issued to me?'), buyer dashboard mental model ('what licenses do I currently hold?'), audit prep ('show me the key list before rotation'). For full mid-lifecycle license details (filter_rules, billing, payouts), buyers consult the buyer portal at opedd.com/buyer. Requires OPEDD_BUYER_JWT.

Generate a procurement-defense compliance dossier via GET /buyer-compliance-report (Phase 11 M4). Per-row dossier shape: 25+ fields including 17 RAG-essential article fields + full license_terms + on_chain_attestation block. Bulk envelopes fan out into per-article rows by iterating metadata.article_ids[]. Self-audit invariant: every successful call writes one license_events row with event_type='compliance_report_generated' BEFORE returning. Window cap: 90 days per call (vs 30-day cap on get_audit_events). For annual audits, paginate via _meta.next_cursor across 4 quarterly windows. Compliance framework anchors (boolean flags) map to EU AI Act Article 53, CDSM Article 4(3), on-chain attestation, TDM reservation. Requires OPEDD_BUYER_JWT.

Retrieve the full body of a licensed article using a buyer API token (opedd_buyer_live_* canonical; opedd_buyer_test_* for sandbox). Requires OPEDD_BUYER_TOKEN env var (create one at opedd.com/licenses after purchasing). Works for per-article licenses (token scoped to that article) and archive licenses (token covers all publisher content). The publisher must have content delivery enabled and must have pushed content for the article. Phase 11 M2 RAG-extended shape: response includes 7 RAG-essential metadata fields — author, language, word_count, content_hash, image_urls, canonical_url, tags. On pre-2026-05-14 historical articles, optional fields (author/language/image_urls/canonical_url/tags) may be NULL. NULL means 'data unavailable for this article', NOT 'explicitly empty' — treat as data-missing when filtering; do not interpret as anti-match.

List articles from a buyer's licensed catalog via GET /enterprise-license (Phase 10 + 11). Returns JSON-format response with paginated articles. Use `since` (ISO 8601) for delta-feed polling — only articles published after the timestamp. Use `cursor` for pagination across pages. Requires OPEDD_ACCESS_KEY (ent_* enterprise access key). For larger bulk corpus pulls, use stream_feed_ndjson (up to 1000 articles per call vs 200 here).

List all licensable articles for the authenticated publisher (requires OPEDD_PUB_BEARER, or legacy OPEDD_API_KEY). Returns articles with titles, descriptions, pricing, and sales statistics. Use article IDs from this list to purchase licenses via purchase_license.

Look up a piece of content on the Opedd registry by URL. Returns the article title, publisher, available license types, and pricing (human republication price and AI training/inference price). Always call this first to check if content is licensable and what it costs.

Browse the public Opedd publisher catalog via GET /publisher-directory. Returns paginated publishers with article counts, pricing (per-article + annual + monthly-forward-feed), plan, and sample articles (RAG-extended metadata). **The primary discovery surface for AI labs to find Opedd-licensable publishers** — distinct from `browse_registry` (which lists issued LICENSES, not publishers). Filter by category (case-insensitive substring), min_articles, or verified status. Public no-auth — useful pre-purchase scoping before buyers commit to enterprise-license POST.

Purchase a bulk enterprise license covering multiple publishers (Phase 10). Returns a Stripe client_secret for payment completion + the enterprise_license_id. After payment, an ent_* access key is emailed to buyer_email. Scopes: 'custom' (pass-through publisher_ids), 'platform_wide' (auto-resolve all opted-in publishers), 'filtered' (Phase 10 filter_rules). License tiers: 'rag' (= ai_retrieval), 'training' (= ai_training, flat-fee not metered), 'inference' (= ai_retrieval), 'full_ai' (writes both retrieval + training records).

Purchase a content license from the Opedd protocol using a Stripe payment method. Returns a license key (format: OP-XXXX-XXXX) and a certificate URL. The buyer receives a Handshake Email with their license key. Set OPEDD_BUYER_EMAIL and OPEDD_PAYMENT_METHOD_ID env vars to avoid passing them on every call. License types: 'human' = republication rights, 'ai' = training dataset rights, 'ai_inference' = inference/RAG rights.

Push your published articles to Opedd so they can be licensed to AI buyers (requires OPEDD_PUB_BEARER — your opedd_pub_ publisher key). Send 1–100 articles per call; batch larger back-catalogues into multiple calls. Each article needs title, url, and html_body — everything else is optional (published_at defaults to now). This is the supply-side companion to list_publisher_content: use it to onboard your archive or push new content with no code, straight from your AI assistant.

Fetch a publisher's RSL Standard manifest via GET /rsl-manifest (Phase 12 Wave 1 W1.1). Public no-auth endpoint — discovery surface for AI agents/crawlers wanting to know what's licensable from a publisher BEFORE going through the buyer-account signup flow. Returns the 4 canonical license types (ai_retrieval, ai_training, human_per_article, human_full_archive) the publisher has opted into, plus the EU CDSM Article 4(3) opt-out posture (`tdm_reservation`). Set `jsonld: true` to request the JSON-LD shape with embedded HMAC-SHA256 signed receipt over the CDSM Article 4(3) reservation state + `tdm:reservationSignedAt` timestamp — regulators can post-hoc verify the reservation was the claimed value at the claimed time. Default `jsonld: false` returns the raw RSL Standard JSON manifest. Per INVARIANTS.md W1.6: this is the PUBLISHER-side CDSM Article 4(3) declaration surface. It is NOT an EU AI Act Article 53 attestation (which is buyer-side, JWT-auth, via article_53_attestation tool).

Bulk-export a buyer's licensed catalog via GET /enterprise-license?format=ndjson (Phase 11 M3). Returns up to 1000 articles per call (collected from line-delimited JSON wire format). Each article emits one usage_records row (analytics-only sentinel 'bulk-export:<request_id>:<article_id>' — not metered-billable per the revenue-model bifurcation invariant). Use `since` (ISO 8601) for delta-feed. Use `cursor` to paginate beyond 1000. Backend supports 5000 articles per call; the MCP cap is 1000 for transport reasonability. Real bulk-ingest pipelines should use the Python SDK (pip install opedd) directly — not via MCP. Requires OPEDD_ACCESS_KEY (ent_*).

Verify the authenticity of an Opedd license key. Returns license details including: article title, publisher, license type, issue date, amount paid, buyer info, and blockchain proof status. Use this to confirm a license is valid before using licensed content.
