This requires 288 API requests per day plus manual tests; the documented free allowance of 100/day is insufficient. Select an X-API-Key Header Auth credential and a Discord Bot account/server/channel.\n\nValidate records and collapse same-page IDs before staging node-scoped static history. New IDs persist only when the complete published, triggered workflow succeeds. A partial failed send can cause earlier messages to repeat on the next poll. Manual tests do not persist static data. No workflow retries or exactly-once delivery guarantee. Inspect/reset the 10,000-entry history when needed. See README for pagination and capacity behavior.\n\nOriginal template contributed by the team behind Live Tennis API, with affiliation disclosed."
