Pyth

Pyth Network is a first-party financial oracle delivering real-time market data — 500+ price feeds spanning crypto, equities, FX, metals, rates, and commodities — to 100+ blockchains. Its pull-based Pyth Core oracle lets applications fetch signed prices from the Hermes service and verify them on-chain in a single transaction with 400ms updates, while Pyth Pro (Lazer) offers enterprise low-latency WebSocket streaming. Additional products include Entropy for on-chain randomness and Express Relay for MEV protection. Pyth exposes public REST/SSE APIs (Hermes, Benchmarks), first-party SDKs across TypeScript, Rust, Python and Solidity, a hosted MCP server, and a published agent-integration skill. Surfaced as a portfolio company of Multicoin Capital.

Pyth publishes 5 APIs on the APIs.io network, including Price Differences API, Price Feeds API, rest API, and 2 more. Tagged areas include Company, Crypto Web3, Oracle, Price Feeds, and Market Data.

Pyth’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, changelog, authentication, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/pyth: open an issue to ask a question, or submit a pull request to add artifacts.
