# The Graph | PubFi Discovery

> The Graph is tracked as an on-chain state source for Ethereum coverage. Decentralized indexing protocol and subgraph ecosystem for querying blockchain application data.

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: current
Directory status: indexed only
Raw claim-safe status: public_source_profile (Public source profile)
Raw claim-safe CTA: Compare sources
Effective agent availability: public_source_profile (Public source profile)
Effective agent CTA: Compare sources
Agent actionability: not actionable
Agent availability reason: The raw claim-safe status is not a current callable or tooling status.
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: Subgraph-based indexing and querying for blockchain application data (source https://thegraph.com/)
- Fixture coverage: On-chain state coverage for the Ethereum fixture target (source https://thegraph.com/)
Best for candidates:
- Subgraph-backed application data queries
- Ethereum ecosystem indexing workflows
Not ideal for candidates:
- Managed RPC endpoint hosting
- General market price aggregation
Use case candidates:
- Query indexed protocol data through subgraphs
- Compare decentralized indexing options for application data
Implementation note metadata:
- schema severity medium
- coverage severity medium
