Perp Funding Rate & Implied Yield Calculator

Recomputes a perpetual-contract funding rate and its simple-annualized implied yield from inputs you declare, for either of two declared funding-mechanism variants: offshore-8h-twap (a continuous TWAP-sampled premium-index-plus-interest-rate-differential-clamp formula, the shape observed on offshore crypto perpetual venues) or kalshi-periodic (a simpler point-in-time price-differential reset, modeled against the CFTC's 2026 regulated-perpetual-contract framework). The mechanism is always a field you declare. An optional prior-print hash chains this funding print to its predecessor, turning a series of same-pair prints into a walkable, cryptographically bound history. This tool complements the Prediction Market Artifact Validator elsewhere in this suite, which validates event-market settlement artifacts, by recomputing the ongoing funding-rate carry on a perpetual position instead.

Scope & reliance
This tool recomputes a funding rate and implied yield from inputs YOU declare against a formula YOU select, and never fetches a live market price or asserts that any venue's own current funding print matches this recompute. The offshore-8h-twap and kalshi-periodic formula shapes are declared modeling conventions rather than requirements drawn from the cited CFTC policy statement (91 FR 33160, June 3, 2026), which describes the funding-rate concept in general regulatory terms and leaves the exact computation to the venue. A match means this recompute of your declared inputs, distinct from confirmation that your venue's actual funding print is correct or that this is investment advice.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `compute_perp_funding_implied_yield`. Task: Recompute a perpetual-contract funding rate and its simple-annualized implied yield for a declared offshore-8h-twap or kalshi-periodic mechanism, with optional hash-chaining to the prior print.
Call it with arguments: {"policy_parameters":{"funding_mechanism":"offshore-8h-twap","venue":"hyperliquid","mark_price":65200,"index_price":65000,"interval_hours":8,"position_notional":100000,"position_side":"long","premium_index_pct":0.02,"interest_rate_pct":0.01,"clamp_pct":0.05}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
