Market headlines from public RSS in one GET: title, URL, publication time and source, newest first, with nothing older than 48 hours. curl: GET /news?topic=markets&limit=20 (topic markets|crypto|tech|world, default markets; limit 1-50, default 20). Response: {"topic":"markets","count":20,"freshness":{"max_age_hours":48,"newest_published_at":"2026-10-16T20:36:00.000Z","oldest_published_at":"2026-10-16T02:12:00.000Z","fetched_at":"2026-10-16T20:41:07.000Z","items_within_window":94,"dropped_older_than_window":12,"dropped_undated":0},"items":[{"title":"Stocks close at a record as earnings beat","url":"https://…","published_at":"2026-10-16T20:30:00.000Z","source":"MarketWatch","age_minutes":11}],"sources":[{"source":"BBC Business","feed_url":"…","ok":true,"http_status":200,"items_in_window":28,"latency_ms":180}]}. The five market feeds are read in parallel at the moment of the call, each with a 6 second cutoff, and every item carries the time its feed published it, so the age of each headline is visible. 0.005 USDC, no account, no key, one GET, one delivery. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
