Bitcoin mempool size and unconfirmed transaction count, via mempool.space API

Reads a vesting plan/stream directly from an on-chain contract on Base — total amount, claimed/unclaimed balance, remaining lockup, current owner/recipient. A direct contract read instead of a dashboard's cached view: the vesting math is verified against the contract on every call, not assumed from an indexer. Two providers, selected by the required provider query parameter: hedgey (TokenVestingPlans) or sablier (SablierLockup, V2/v4). provider is REQUIRED — plan_id/stream_id numbering overlaps between the two contracts (e.g. id 2 is a real, distinct plan on both at once), so there is no safe default or auto-detection; a missing or invalid provider returns 400, never a guess.

Query real-time stablecoin supply yield pools from Barker's index of 500+ DeFi protocols.

single-fact naics lookup. Complete for the bundled 2022 vintage: all 2129 NAICS 2022 codes at levels 2 through 6, titles verbatim from the Census workbook, with the three range-spelled sectors (31-33, 44-45, 48-49) expanded to one entry per member sector. NAICS is a closed set, so a well-formed code absent from this snapshot is absent from the 2022 vintage. Refresh is a redeploy, never a live fetch.

Deterministic mining P&L for Animica L1 at a named chain height. The per-block reward comes from the node's own live block template, not the published subsidy split (which is wrong by 2x on mainnet); the block interval and difficulty are measured, the ANM price is the NonKYC bid. Buy before pointing hardware here: it states the FIXED daily pot every miner shares, your share AFTER you join, and how much you dilute the incumbents. No model, no growth curve. Backend down = 503, no charge.
