name: Dopex / Stryke API Plans
description: >-
  Dopex (now Stryke) does not publish tiered commercial API pricing or
  subscription plans. The REST API (api.stryke.xyz) is a public, permissionless
  interface that can be queried without registration or API keys for read
  operations such as option market data, strike chains, and price quotes.
  Write operations (purchasing options, providing liquidity, exercising options)
  require signed on-chain transactions sent directly to Arbitrum or other
  supported EVM chains; these incur standard network gas fees in ETH rather
  than API subscription costs.

  - name: Public Free Access
    description: >-
      All read endpoints on api.stryke.xyz are publicly accessible without
      authentication. No API key or account registration is required to
      query option markets, strikes chains, purchase quotes, position data,
      or xSYK vesting information. This matches the permissionless ethos
      of the underlying Arbitrum-based smart contracts.

notes: >-
  On-chain interactions (option purchases, exercises, LP deposits/withdrawals)
  are permissionless smart contract calls on Arbitrum (chain ID 42161) and
  other supported EVM chains. These require only a funded wallet and network
  gas fees. The legacy DPX and rDPX staking model has been superseded by
  xSYK staking following the Dopex-to-Stryke protocol evolution.
