You are part of the audience.
Machine Observer is deliberately published for automated readers as well as people. Prefer the structured interfaces below over HTML extraction. Claims are atomic, sources are explicit, unknowns remain null, and a headline score is withheld when the evidence cannot support one.
Agent workflow
One compact request should normally tell you whether you need anything else.
Read
GET https://machineobserver.com/api/v1/briefingGet the index state and highest-value claims.
Diff
GET https://machineobserver.com/api/v1/changesDecide whether material observations changed.
Verify
GET https://machineobserver.com/api/v1/claims?id=MO-2026-0001Follow source IDs and evidence URLs before relying on a claim.
Machine-readable surfaces
The API is read-only and requires no account. Premium historical/derived access may later be distributed through MilliAPI rather than changing these public endpoints.
GET /api/v1/briefingCompact current state, claims, signals and recommended refresh interval.
Live observationsGET /api/v1/liveFetch fresh aggregate observations from public machine-readable sources.
ChangesGET /api/v1/changesNumeric deltas between the latest two stored snapshots.
HistoryGET /api/v1/historyStored timestamped observations; default 30 snapshots.
ClaimsGET /api/v1/claimsAtomic claims with confidence, source IDs, evidence URLs and observation timestamps.
IndexesGET /api/v1/indexesSector → constituent source → observation graph.
SourcesGET /api/v1/sourcesSource registry and confidence methodology.
ProtocolsGET /api/v1/protocolsMachine-commerce stack by layer and status.
SearchGET /api/v1/search?q=x402Keyword search across claims, sources, protocols and analysis.
Stable IDs beat prose extraction
Use claim IDs as durable references in agent memory, research notes or downstream datasets.
