Dated, source-backed observations on x402 paid APIs and agent commerce, with the curator's judgment and explicit limits. Coverage varies by edition, so read the free headlines and sample before paying.

Latest edition: 2026-11-04. Archive depth: 29 dated editions. Missing dates are not backfilled.

Publishing rhythm (free): The live edition 2026-11-04's current version was generated at 2026-11-04T07:12:02Z (18.9 hours before this document was served). The archive holds 29 edition dates across the 47 calendar days 2026-09-19 to 2026-11-04, and its longest gap between editions is 5 days; today's distance from the edition date is within that gap, so a quiet stretch like this has happened before. No next-edition time is promised. If you already hold this edition, check https://draconic21-x402-api.onrender.com/v1/signal_delta/availability?since_date=2026-11-04 (free) before buying again.

Archive headlines

29 dated editions listed below, newest first, 2026-09-19 to 2026-11-04. Each date has its own anchor (/signal#d-YYYY-MM-DD) and its own page (/signal/YYYY-MM-DD), which the feed items link to. One-table archive view with every hash and Bitcoin block: /signal/archive.

Headlines only. Judgment, buyer value, action hints and sources are in the paid editions. Transfer counts and listing activity mentioned in headlines do not establish independent buyers or verified sales. Not financial advice.

Badges link a headline to the dated calls it made or settled on the free track record (63 calls: 38 confirmed, 5 partial, 20 falsified as our misses, 0 open). Misses are shown, not hidden.
