api record

Kairos Signal: provenance-first DePIN intelligence API. 374 live networks + 129 Bittensor subnets (503 symbols), 19,379 verify-stamped live series — every value ships {source, as_of, verify_url} pointing at the ORIGIN endpoint. Start with register_agent ($5 free credits, no card (first 3 keys per IP per 30 days)), then list_products ($0.49-$29.99 per dataset, delivered inline). USDC on Base requires signed sender verification and a current quote; see https://kairossignal.com/docs/crypto.html. Stripe returns a checkout link. Try before registering: GET https://kairossignal.com/try returns 3…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • register_agent changes data unknown never probed

    START HERE. One call: get an API key instantly (no card, no human, no Stripe, ~5 seconds) plus $5 free credits, no card (first 3 keys per IP per 30 days). Past that per-IP limit a key is still created, at $0, and the response says so — it is never a silent zero. Works immediately: query live DePIN telemetry (503 symbols, every value carries a verify_url you can check yourself), GPU inference, DAG manifold. Try get_data_dictionary first if you want the coverage spec, or GET https://kairossignal.com/try with zero setup. Nothing to cancel; credits just sit there until you spend them. Then list_products to see what $0.49+ buys.

  • topup_credits moves money unknown never probed

    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.

  • get_derivation_ledger reads unknown never probed

    DERIVATION TRUTH: raw upstream payloads, SHA-256-pinned, with the exact collector code hash for each fetch. Replay any published value: fetch the verify_url yourself, run the pinned code, compare. Answers 'a hash proves a footprint, not the derivation' — divergence from origin is mechanically detectable. Free.

  • list_products reads unknown never probed

    Browse purchasable products with prices in credits ($1 = 1 credit). DePIN supply-telemetry, provenance, derivation-replay, history, grades and the intel bundle are BUYABLE NOW from $0.49. 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_data changes data unknown never probed

    Buy a product with your credits; the data ships inline in the response. Deliverable today: the whole depin_* family plus depin_intel_bundle — 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.

    ONBOARDING SPEC: freshness, history depth, coverage and endpoints per feed (depin_onchain, depin_daily, health_profiles, signal_ledger, market_ticks, zk_footprints). Machine-legible; answers 'how stale is this and how far back does it go' for every feed. Free, no key.

  • fetch_dataset reads unknown never probed

    Query records from a dataset with limit/offset. Free tier: 10 records per query. For depin_onchain, raw archived observations, including rejected rows, are retained. observation_quality reports limited PKT airdrop checks; not_checked means not validated. This read-time annotation is not covered by original proof hashes.

  • verify_footprint reads unknown never probed

    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).

_ try it over mcp 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.
