15 tools

• 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. Read-only, no

• 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 inc

• 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 heade

• 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 figur

• 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 only needed for purchase_data, check_balance and topup_cre

• 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. Signal-

• purchase_data

  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 p

• 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 ({"m

• check_balance

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

• list_datasets

  List the current dataset catalog with record counts. Browsing is free; existing query and daily-call limits apply.

• 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 g

• 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

  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,

• 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

• 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 tha
