Publications on Opedd now: Coffee in the Desert (Geopolitics); World Politics Review; Understanding AI (Technology); Geopolitical Dispatch (Geopolitics); The Realistic Optimist (Technology); SemiVision (Technology); Embedded Finance Review (Technology); Quantum Strategy & Geonomics (Markets); Shanaka Anslem Perera (Finance); Matter of Fact (Geopolitics & Foreign Policy). Returns licensed passages from publications on Opedd that answer a question, each with a citation to the source article. Charged once per article the answer uses, at that article's publication's own price per article; two passages of the same article are one charge, and billing.articles_charged reports how many were charged. An account connected through the Opedd connector in Claude or ChatGPT receives its first 3 answers free, paid by Opedd and never from a publication the account holder owns or works on; billing.free_answers_left reports how many remain. After that, answers are billed to the card on the account, added at opedd.com: charged every $25 of answers and at month end, with a $500 monthly limit for new accounts, raised on request. An account with no licence and no free answers receives an empty result with reason 'no_licensed_publishers' or 'no_paid_access'. Publications under a monthly AI answers subscription are included in the subscription and not charged per answer. Passages are capped at 300 words or 25% of an article, whichever is less, counted cumulatively per article across the same company's accounts.
