Douro Labs primary-source snapshot

Fetched: 2026-08-10 UTC

1) Douro Labs as a named data-distribution company and initial Pyth contributor

Source: https://www.dourolabs.xyz/

Selected excerpts from official materials:

Douro Labs is at the forefront of data aggregation and distribution.

We help decentralize data services and enhance access to real-time, once-exclusive market data for the finance industry by contributing to some of the most important projects in the space, such as the Pyth Network, where we are one of the initial contributors.

Why it matters:

  • This is the cleanest first-party statement that Douro Labs is a real entity boundary and not just a hostname behind Pyth infrastructure.
  • It also ties the company directly to Pyth as an initial contributor, which justifies a company note adjacent to the existing Pyth project notes.

2) Pyth homepage commercial-intake lane

Selected excerpts from official materials:

Schedule demo

[link target] https://data.dourolabs.xyz/pyth-interest-form

Why it matters:

  • The premium price-feed business-development path is routed through a Douro-hosted domain rather than an anonymous internal form.
  • That makes the commercial access lane around Pyth’s premium data path visibly company-shaped.

3) Pyth Developer Hub home and API-doc boundary

Selected excerpts from official materials:

Request access for the Pyth Ultra Low Latency price feeds.

Explore the complete API reference for Pyth Pro.

[link target] https://pyth-lazer.dourolabs.app/docs

Why it matters:

  • The developer docs themselves point users toward a Douro-branded API documentation domain for the premium product.
  • This is strong evidence that the low-latency access lane is not just a protocol feature; it is an operated service surface.

4) Pyth Pro API-key acquisition and endpoint fleet

Source: https://docs.pyth.network/price-feeds/pro/acquire-api-key

Selected excerpts from official materials:

This guide explains how to acquire an API key for Pyth Pro, which is required to authenticate websocket connections and authenticated HTTP endpoints.

const client = await PythLazerClient.create( [ “wss://pyth-lazer-0.dourolabs.app/v1/stream”, “wss://pyth-lazer-1.dourolabs.app/v1/stream”, “wss://pyth-lazer-2.dourolabs.app/v1/stream”, ], “YOUR_API_KEY”, );

curl -H “Authorization: Bearer $PRO_API_KEY”
“https://pyth.dourolabs.app/v1/fixed_rate@200ms/price?ids=1&timestamp=1704067200000000”

Browser and frontend apps must not embed the key — route requests through your own backend, which injects the header before forwarding, or use the short-lived JWT flow.

Why it matters:

  • This is the strongest primary-source evidence that the premium feed path depends on authenticated, operator-run Douro-hosted infrastructure.
  • It also makes the real control surface legible: API keys, websocket/HTTP access, and service-mediated authentication.

5) Pyth Pro getting-started defaults

Source: https://docs.pyth.network/price-feeds/pro/getting-started

Selected excerpts from official materials:

Pyth Pro is a high-performance, low-latency service that provides real-time financial market data.

const client = await PythLazerClient.create({ urls: [ “wss://pyth-lazer-0.dourolabs.app/v1/stream”, “wss://pyth-lazer-1.dourolabs.app/v1/stream”, “wss://pyth-lazer-2.dourolabs.app/v1/stream”, ], token: process.env.ACCESS_TOKEN!, });

Why it matters:

  • The default connection pattern shown to integrators routes them into Douro-hosted infrastructure from day one.
  • That is exactly the sort of company-shaped operational gravity the companies/ layer is meant to preserve.

6) Douro-hosted API documentation surface

Source: https://pyth-lazer.dourolabs.app/docs

Selected excerpt from official materials:

Pyth Pro Router API Documentation

Why it matters:

  • Even the premium-router docs live on a Douro-branded domain, reinforcing that the delivery and routing boundary is attached to a named operator.

Notes

  • This pass was meant to split the Douro Labs company boundary out from the existing pyth-network and pyth-pro notes.
  • The useful distinction is between Pyth as oracle network/product surface and Douro Labs as the visible company operating much of the premium low-latency delivery and customer-access path.
