Pyth Pro primary sources

Reviewed: 2026-05-14 UTC Project file: ../projects/pyth-pro.md

Primary sources reviewed

  1. Pyth Pro overview — https://docs.pyth.network/price-feeds/pro

    • States that Pyth Pro was previously known as Pyth Lazer.
    • Frames the product as customizable, enterprise-grade price data delivered directly from first-party publishers.

  2. Acquire an API key — https://docs.pyth.network/price-feeds/pro/acquire-api-key

    • Shows that websocket access is authenticated with API keys obtained through Pyth Terminal.
    • Confirms the access-control layer is an explicit part of the product surface, not just an implementation detail.

  3. Getting started — https://docs.pyth.network/price-feeds/pro/getting-started

    • Documents websocket connectivity through named pyth-lazer-*.dourolabs.app endpoints.
    • Shows the current SDK name @pythnetwork/pyth-lazer-sdk, preserving the older Lazer naming under the newer Pyth Pro brand.

  4. Subscribe to prices — https://docs.pyth.network/price-feeds/pro/subscribe-to-prices

    • Requires connections to all listed websocket endpoints for redundancy during deployments.
    • Documents feed selection, property selection, binary-format selection, and delivery-channel selection as subscriber-controlled parameters.

  5. Payload reference — https://docs.pyth.network/price-feeds/pro/payload-reference

    • Explains the structure of parsed payloads and signed binary payloads.
    • Lists channel-speed choices and supported signature / format variants such as evm, solana, and leUnsigned.

  6. EVM integration guide — https://docs.pyth.network/price-feeds/pro/integrate-as-consumer/evm

    • Shows the separation between offchain subscription and onchain verification.
    • Documents contract-side verification fees and SDK parsing flow for signed updates.

  7. Pyth price-feeds / pricing page — https://www.pyth.network/price-feeds

    • Exposes commercial tiers, latency levels, coverage differences, and display / non-display / redistribution rights.
    • Notes that data is distributed through authorized Pyth Data Distributors.

  8. Public repository — https://github.com/pyth-network/pyth-lazer-public

    • Confirms a dedicated public codebase exists for Pyth Pro contracts, SDKs, and tools.

  9. Raw repository README — https://raw.githubusercontent.com/pyth-network/pyth-lazer-public/main/README.md

    • Confirms the repository is positioned as Pyth Pro contracts, SDKs, and tools.

Key mechanism notes

  • Pyth Pro is a distinct low-latency distribution layer inside the broader Pyth stack, not just a marketing synonym for the base oracle network.
  • The main control surfaces are API-key issuance, operator-run websocket routing, feed/property/channel entitlement, signed-payload format choices, and licensing / redistribution policy.
  • Its most reusable comparison value is showing how a supposedly unified oracle system can split into publisher sourcing, offchain delivery, chain-specific verification, and commercial rights management.
