• register_agentA

  Kairos Signal — DePIN TelemetryA

  Creates an API key for this agent and grants the free starter credits ($5 free credits, no card (first 3 keys per IP per 30 days)). Past the per-IP limit a key is still created, with $0, and the response says so. A key is only needed for purchase_data, check_balance and topup_credits; every read-only tool works without one. email is optional and used for delivery and top-up notices.

• get_derivation_ledgerA

  Kairos Signal — verifiable DePIN data APIA

  Returns the derivation ledger. With a symbol: the archived raw upstream payloads (SHA-256 pinned) and the collector code hash behind that network's recent fetches, so a published value can be re-derived independently. Without one: the symbols that have ledger entries. Read-only, no key. To compare a live value with its upstream right now, use verify_value.

• get_statsA

  Kairos Signal — DePIN TelemetryA

  Returns the row count of every dataset served here (depin_onchain, market_ticks and the rest), their total, the scope statement and the free-tier limits. No arguments, no key, read-only. For one network's live values use get_network; for freshness and history depth per feed use get_data_dictionary.

• topup_creditsA

  Kairos Signal — DePIN TelemetryA

  Add credits. Card (one call): {"method": "stripe", "amount": N} where N is $20 or $99 — returns a Stripe checkout_url already bound to your api_key, and credits post automatically once Stripe confirms payment at $1 = 1 credit. No human step and no wallet needed. USDC on Base ({"method": "usdc"}) is also accepted but requires more work: verify your sender first via POST /v1/credits/crypto/challenge and /verify with X-API-Key, sign the returned challenge with your own EOA, then pass the verified from_address and send only after a successful quote — credit requires finalized Base evidence.

• verify_footprintA

  Kairos Signal — DePIN TelemetryA

  Retained Merkle-membership check for one depin_onchain observation: stamp_day (YYYYMMDD), leaf_index (0-based row in /attestations/batch_<day>.tsv), expected_row_sha256. verified=true ONLY when the row at that index hashes to expected_row_sha256 AND its inclusion path reaches that day's manifest merkle_root. Says nothing about Bitcoin status or upstream accuracy. Other datasets: unsupported (no retained proof).

• find_networksA

  Kairos Signal — DePIN TelemetryA

  Looks up DePIN networks (and Bittensor subnets) that have live data, by name or ticker, e.g. 'akash', 'helium', 'FIL'. Returns symbol, name, category and the network's public page. Use it to get the symbol that get_network, get_metric_history and verify_value take. Read-only, no key.

• list_productsA

  Kairos Signal — DePIN TelemetryA

  Browse purchasable products with prices in credits ($1 = 1 credit). DePIN supply-telemetry, provenance, derivation-replay, history and the intel bundle start at $0.49. Grade purchases are conditional on measured-grade availability; check /v1/credits/pricing before buying. Signal-feed tiers, DAG-manifold tiers and mcp_unlimited are priced but NOT yet purchasable: their entitlement is not wired into the serving API, so purchase_data refuses them with 503 not_yet_deliverable rather than charging you for nothing. Call after register_agent.

• purchase_dataA

  Kairos Signal — DePIN TelemetryA

  Buy a product with your credits; the data ships inline in the response. Deliverability is product-specific, including grade availability; check /v1/credits/pricing before buying — call list_products for the live prices rather than trusting a figure restated here, which is how a price in a second place drifts from the first. The signal_*, dag_* and mcp_unlimited keys are priced but return 503 not_yet_deliverable — they are deliberately blocked, not broken, because nothing grants their entitlement yet. Credits buy DATA; they do not change your access tier. Use api_key from register_agent.

• get_metric_historyA

  Kairos Signal — DePIN TelemetryA

  Returns the daily series for one network metric (one point per UTC day, with how many observations backed it), e.g. symbol=AKT metric=GPU_ACTIVE. Days with no observation are absent, never zero. The free tier serves the last 7 days and says so in window_notice; an X-API-Key header on the connection serves your tier's window. Read-only.

• get_networkA

  Kairos Signal — DePIN TelemetryA

  Returns the latest first-party measurements for one DePIN network (GPU and CPU capacity, storage, node or hotspot counts, on-chain totals), each with value, unit, as_of, freshness and the verify_url on the network's own API that you can open to check it. Market prices are not included. metric_filter narrows by substring; stale readings are omitted unless include_stale is true. Read-only, no key.

• verify_valueA

  Kairos Signal — DePIN TelemetryA

  Re-reads the upstream API behind one of our values right now and reports where the same number appears in the upstream response (JSONPath), the relative difference, and a verdict: exact, within_1pct, within_10pct, no_matching_field or not_checkable_by_get. Use it to check a figure before relying on it. Makes one GET to a third-party API; read-only.
