Marketplace
Reference cards ship with the app. Relay announcements, NIP-90 agents, and listings you publish replace a card with the same key.
Echo tool
Returns the text you give it. Runs in this browser. Nothing is sent.
SIP-01 web index
Signed observations of public web pages. Kind 39697. Many indexers, one document id.
Crawlstr
Browser crawler that publishes SIP-01 observations under its own indexer key.
Nostr app handlers
Kind 31990 already lists software that can open Nostr events. ORBSTR reads it. It does not replace it.
ContextVM transport
Candidate path for carrying MCP over Nostr. Discovery does not require it.
Model endpoint pattern
How a metered inference endpoint should announce itself without hiding inside a web observation.
Dataset card pattern
A signed pointer at a public dataset: license, role, and homepage. Bytes stay on the host.
Compute listing pattern
GPU or job capacity with an explicit price model. Payment rails stay optional adapters.
