Find missing contextually relevant internal links in supplied pages

Recent internal transactions (value transfers triggered by a contract call -- swaps, withdrawals, contract creations) for a wallet or contract address on Ethereum, from Etherscan's V2 API. These never show up in a normal txlist but often carry the actual fund movement. Supports optional limit (default 25, max 100). $0.01/call.

Internet Archive lookup: whether a snapshot of a URL exists and its closest capture to a given date — read pages that are now dead

Individual yen foreign-exchange intervention operations (date, amount, currency pair) from the Ministry of Finance's official record, 1991-present. Quarters with no intervention are simply absent from the list rather than zero-padded. Factual published data only; not investment advice or a signal to trade on.

Checks whether a tank/vessel reported level change is physically consistent with its metered flow-in/flow-out via conservation of mass. Pass asset_id, flow_in, flow_out, level_start, level_end, dt_seconds (>0), tank_area (>0), optional noise_floor (default 0.5). Fully deterministic, no LLM, no trained model. Inspired by Barbhaya et al. 2025 physical-invariant residual check — flags inconsistency and direction, does not assert a specific cause.

Inverse-vol risk parity weights from return series. Call when allocating across assets by inverse volatility offline. Returns weights summing to 1 as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

Investment Morning Brief — latest weekly investment intelligence brief synthesized from 17 finance/investing podcast channels

Fetch investor data including VCs, angels, PE firms, corporate investors, accelerators, and more. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

Invoice field verification for AI agents: arithmetic consistency of invoice fields, line-item totals, and accounting JSON. 0.001/call.

What standard does this Base contract implement? Detect ERC-20, ERC-721, ERC-1155 and ERC-165 support plus EIP-1967 proxy control slots in one cheap bounded check, shared across agents for as long as the code at the address is unchanged, up to 7 days, and only for a few blocks when the target is an upgradeable proxy. Positive-sum by design: $0.02 when nobody has checked this contract yet, $0.01 once another agent has — and the wallet that computed it first earns a share of every reuse.

IPv4 CIDR calculator: network, broadcast, netmask, wildcard, usable host range and count, plus optional contains-IP membership check.
