api record

Kairos Signal serves measured supply-side telemetry for DePIN (decentralized physical infrastructure) networks: 319 live networks + 129 Bittensor subnets (448 symbols), 18,715 verify-stamped live series. Every value carries source, as_of and a verify_url on the network's own API. Answer questions with the read-only tools, no key needed: find_networks (name or ticker -> symbol), get_network (latest values, each with its verify_url), get_metric_history (daily points), verify_value (re-reads the upstream now and says where our number appears). Coverage counts: get_stats. Freshness and history…

_ is it live, free and safe measured by this hub
Is kairos-signal-mcp live?
Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.
Is kairos-signal-mcp free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does kairos-signal-mcp have?
5 tools: World Intelligence (measured physical-world telemetry), Formal Verification Report, DePIN Supply Telemetry, Derivation Ledger (replayable derivation), Purchase Data Product.
Is kairos-signal-mcp safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes

_ what it can do 5 tools
5 auth-required 5 of 5 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • world_intelligence auth-required never probed

    Measured physical-world feeds with the same provenance guarantees as the DePIN rows: maritime AIS vessel counts from national receiver networks, GPS-interference map history, airspace (military aircraft airborne, active US temporary flight restrictions) and Bittensor subnet economic metrics. Current figures are served live on the A2A agent card (https://a2a.kairossignal.com/.well-known/agent-card.json); this static copy states none, so it cannot go stale.

  • verify_proofs auth-required never probed

    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.

  • depin_intelligence auth-required never probed

    Supply-side telemetry for 319 live networks (290 first-party, 7,337 first-party series); the other live networks are on-chain only. Provenance-first: series read from each network's own API or chain (node, capacity and utilisation series where a network publishes them; for many networks only token supply and holder counts read from the token contract), plus daily snapshot history. Every value carries its source and a public verify-yourself URL. From $0.49.

  • derivation_ledger auth-required never probed

    Recorded derivation-ledger rows carry the upstream body we received (raw_body), its SHA-256 and the collector build hash (code_sha256), for the collector sources listed in the free index. Replay: re-issue each row's replay request (JSON-RPC origins are POSTs whose request body was not recorded) -> compare with raw_body -> compare the derived values with /v1/network/<SYM>; each row's proof says whether its derived values came from that fetch. The pinned build's source is not served publicly. Free index: GET https://kairossignal.com/v1/derivation?symbol=AKT. The newest 100 rows with their raw bodies (optionally for one symbol): $2.99.

  • purchase_data moves money auth-required never probed

    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.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 68a50cf0a5e37347.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/68a50cf0a5e37347/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
