Machines pay. Humans watch.

npayload already provides keys, metering, billing, replay, consumer groups and an audit trail, so Wickfeed runs no subscriber accounts and no billing of its own. It also means one realtime door: no public HTTP, WebSocket or SSE endpoint serves realtime event JSON to an unauthenticated caller.

No. The free tier is realtime and capped at five events an hour. Delay is the gate for the public human surface, which runs at least fifteen minutes behind. A rate limit is the gate for machines, because an agent cannot evaluate a delayed feed.

Resolved contracts are archived and their identifiers stay permanent. A new book is registry entries plus sources, and its events validate against the same envelope version with no schema change, so a handler written for one book processes the next one with no code changes.

No. Wickfeed observes public sources and publishes its own analysis. A registry mapping carries the venue name, that venue’s own reference and a public URL, and never a price, a size or order book depth.

Not on a standard subscription, which covers your own systems. Surfacing Wickfeed output to your users is a runtime deal, priced per deal.

There is no published uptime number yet, and we will not invent one before the engine has run. Every interruption is recorded as a gap with its exact start and end and shown on the status page. Named commitments come with desk and runtime agreements.
