# SwellStrike

> Free options-planning calculators and practical educational guides. SwellStrike is not a brokerage, signal service, or investment adviser; calculator results are planning estimates, not guarantees.

## Machine integration (experimental)

- Discovery manifest: https://www.swellstrike.com/.well-known/ai-payments.json
- Versioned expected-move resource: GET https://www.swellstrike.com/api/machine/v1/expected-move
- Required query parameters: underlying (positive number), iv (annualized implied volatility percent), days (integer days to expiration). Optional multiplier defaults to 1.
- The manifest is descriptive and experimental, not an industry standard. It publishes the canonical input/output schemas, examples, pricing, and current availability.
- The machine resource is Base Sepolia testnet-only when enabled. It is currently unavailable until SwellStrike configures its testnet payment environment; human-facing calculators remain free.
