# OnFinality | PubFi Discovery

> OnFinality is tracked as an RPC infrastructure and on-chain state source for Polkadot coverage. Managed RPC, archive node, and infrastructure services for Polkadot and other blockchain networks.

Source: Discovery catalog fixtures consumed by the public Discovery routes.
Format: text/markdown; charset=utf-8
Inclusion gate: source.isIndexable is true; draft/noindex records are not emitted as markdown detail pages.
Canonical SEO rule: the HTML detail page is the canonical SEO URL; this Markdown route is an agent-readable mirror.
Agent availability rule: raw claim-safe status is preserved for provenance, but actionability uses effective agent availability. Degraded pages require revalidation even when the raw status names a gateway, x402, or MCP surface.

Public status: degraded
Directory status: coming soon
Raw claim-safe status: public_source_profile (Public source profile)
Raw claim-safe CTA: Compare sources
Effective agent availability: needs_reverification (Needs re-verification)
Effective agent CTA: Reverify before live use
Agent actionability: requires revalidation
Agent availability reason: The source is degraded, so raw callable or tooling status is not treated as actionable.
PubFi gateway readiness: not_routeable (PubFi gateway not routeable yet)
PubFi gateway summary: This Discovery source is available for source evaluation and comparison, but PubFi does not publish a production-callable gateway route for it yet. Use this page to compare the provider, signal demand, or start a procurement/integration review instead of attempting a PubFi gateway call.
PubFi gateway guidance:
- Do not infer a PubFi gateway path from this Discovery page.
- Use the official provider docs for direct provider integration until a PubFi readiness entry marks this source gateway_available.
- Use the Discovery request or demand-signal CTA to register integration interest with PubFi.
- Supplier procurement, paid-plan approval, and upstream credential setup require explicit review before PubFi can route the source.

Key facts:
- Primary coverage: Managed RPC, archive node, and infrastructure services for Polkadot and other blockchain networks (source https://onfinality.io/)
- Fixture coverage: RPC infrastructure and on-chain state coverage for the Polkadot fixture target (source https://onfinality.io/)
Best for candidates:
- Polkadot RPC and archive access
- Teams comparing managed blockchain infrastructure providers
Not ideal for candidates:
- Standalone market price datasets
- Automation-approved governance summaries
Use case candidates:
- Route application reads to managed Polkadot infrastructure
- Compare RPC infrastructure options before provider selection
Implementation note metadata:
- auth severity medium
