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.

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.

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.

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.

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.

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 The archive_method + forward_method fields are the two onboarding-workflow inputs Opedd's setup wizard reads (one for historical content backfill, one for new-content forward stream).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.

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).

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).
