Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.

get_network_signals | Returns the current scheduled Hodge and lag-relation snapshots, coverage, observation times, invariants and timestamped history for configured market, DePIN and world cohorts. Requires an API key on a paid tier that includes the engines capability (https://kairossignal.com/pricing), sent in the X-API-Key header of the MCP connection; the free starter key from register_agent does not include it, an params: none |
find_networks | 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; a network with no public ticker is listed under its internal reference (symbol_kind 'internal_ref'). Read-only, no key. params: query, category, limit |
get_network | 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. params: symbol*, metric_filter, include_stale, max_metrics |
get_metric_history | 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. params: symbol*, metric*, days |
verify_value | 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. params: symbol*, metric* |
register_agent | 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 needed for purchase_data, check_balance, topup_credits and every tool that charges credits; get_network_signals needs one on a paid tier with the engines capability, which the fr params: email, agent_name* |
list_products | 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. 30-day Pro access to the DAG manifold API is sold as dag_manifold_30d and delivers its API key inline. Not purchasable, refused params: none |
purchase_data | Buy a product with your credits; most products ship their data 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_* keys (retired, not sold), dag_pro (sold as dag params: product_key*, api_key*, idempotency_key |
topup_credits | 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, two modes. micro_decimal, no wallet signature: {"method": "usdc", "mode": "micro_decimal", "amount": N} with N whole USDC f params: api_key*, method*, mode, amount*, from_address, tx_hash |
check_balance | Check your remaining credit balance. Use after purchases to see remaining credits. params: api_key* |
list_datasets | List the current dataset catalog with record counts. Browsing is free; existing query and daily-call limits apply. params: none |
get_stats | 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. params: none |
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. params: none |
get_derivation_ledger | Returns the derivation ledger index. With a symbol: up to 20 recent archived upstream fetches behind that network, each with time, verify_url, the SHA-256 and size of the raw payload, the collector code hash and the fetch status, so a published value can be traced to the exact bytes and build that produced it (the payload bytes themselves are the paid derivation_replay product). A network with liv params: symbol |
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. params: dataset*, limit, offset |
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. Returns JSON: row_sha256, merkle_r params: dataset, stamp_day*, leaf_index*, expected_row_sha256* |
get_hodge_regime_sieve | Paid: 1 credit ($1.00) per answered call, charged once and only after a non-empty answer is computed; an unavailable answer, a refusal or an error costs nothing. Send your API key in the X-API-Key header or as api_key. Each call is a new answer and a new charge (no idempotency key).
