Kairos Signal — Data A2A Adapter

AgentA2A

A2A adapter for Kairos Signal data services. Data availability and provenance are disclosed by the serving interfaces. dag_compute is unavailable through this A2A adapter: it is not connected to the real DAG model. Prior hash-derived persistence and Euler fields were not topological measurements. N…

Declared by sources

What the publisher says

Attributed to the source that supplied each field. Treated as claims, not facts.

Declared skills

DePIN Supply Telemetry — First-party infrastructure telemetry for 369 live networks (318 first-party, 7,413 first-party series), provenance-first: supply/node/utilisation metrics from each network's own API or chain, daily snapshot history across the whole live set, capacity-utilisation pairs on 8 networks. Every value carries its source and a public verify-yourself URL. From $0.49.
Derivation Ledger (replayable derivation) — Recorded derivation entries carry upstream payload bodies and payload/code SHA-256 fields; consult the derivation index for recorded coverage. Replay chain anyone can run: fetch the verify_url yourself -> run the pinned code -> compare to published values. Divergence is mechanically detectable. Free index: GET https://kairossignal.com/v1/derivation?symbol=AKT. Full raw-payload access $2.99. Verified: 22/22 Akash metrics re-derived from live origin matched published values.
World Intelligence (measured physical-world telemetry) — Measured physical-world feeds with the same provenance guarantees as the DePIN rows: maritime AIS (4,148 vessels tracked latest from 2 national feeds — Norway 3,491, Finland 657), 26 satellite constellations, 29 days of GPS-jamming map coverage (2026-07-25 to 2026-08-22), BitTorrent DHT (6,416 servers measured, ~2.16M nodes implied), Nym mixnet (1,096 bonded nodes), Bittensor (129 subnets with economic metrics), airspace (437 military aircraft airborne, 122 active TFRs latest). Estate-wide: 108…
Query Federal Contracts — Search tracked federal award records (USASpending-sourced). Results include DAG-computed relationship scores. Coverage and provenance disclosed per query; no aggregate-total claim is made.
Purchase Data Product — Programmatic purchase of a Kairos data product with prepaid credits. Availability is product-specific; successful purchases deliver inline. Withdrawn products are refused, not charged. Personal-contact/lead products are not offered.
Formal Verification Report — Returns the real formal verification report: kernel-checked Lean4 theorems (CostIdentity, GateFailClosed) + Z3/SMT proofs + 26 property/system tests, 5 estate invariants verified, reproducible via formal_verification/run_all.sh. No performance/AUC claim (prior AUC figures were leakage, retracted 2026-08-09). Free — no API key required.
