Kairos Signal

Register Agent

START HERE. One call: get $5 free credits + API key, instantly (no card, no human, no Stripe, ~5 seconds). Works immediately: query live DePIN telemetry (501 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.

List Products

Browse all purchasable products with prices in credits ($1 = 1 credit). Includes DePIN supply-telemetry data, signal feed tiers ($9.99-$399.90/mo), DAG manifold API ($2.99-$9.99/mo), GPU compute, and MCP unlimited access. Call after register_agent to see what to buy.

Purchase Data

Buy a product with your credits. Products: DePIN supply-telemetry snapshots, DAG manifold API (dag_pro/dag_quant/dag_enterprise), signal feed tiers, GPU compute, MCP unlimited. Use api_key from register_agent.

Topup Credits

Create a USDC top-up intent before transferring funds: provide from_address and follow the returned transfer instructions. Alternatively, get a Stripe checkout link for your human operator to complete.

Check Balance

Check your remaining credit balance. Use after purchases to see remaining credits.

List Datasets

List all available datasets with record counts. Free to browse — market ticks, DePIN network stats, technical indicators, US county atlas, ZK footprints.

Get Data Dictionary

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.

Get Derivation Ledger

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.

Fetch Dataset

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

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).
