# SubQuery Network | PubFi Discovery

> SubQuery Network is tracked as an on-chain state source for Polkadot coverage. Decentralized indexing and query services for blockchain application data across Polkadot, Ethereum, and other ecosystems.

Source: checked-in public Discovery data plus the exact live Registry snapshot observed for this response.
Format: text/markdown; charset=utf-8
Inclusion gate: source.isIndexable is true and readiness_flags.llms_export_ready is true; draft/noindex and LLM-export-excluded 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.
Execution authority: current PubFi routeability comes only from /v1/capabilities and the matching runtime /openapi.json. Checked-in editorial status does not make a provider executable.

Editorial posture reason: This checked-in status describes editorial publication only; it is never PubFi execution authority.
PubFi gateway readiness: not_present (Not present in the active Registry)
PubFi gateway summary: The active signed Registry generation has no route for this provider. Discovery inclusion and upstream documentation do not make a provider executable through PubFi.
PubFi gateway guidance:
- Use the official provider documentation for direct integration.
- A future collected source becomes executable only after the normal evidence, policy, health, and generation pipeline accepts it.

Pricing model: Prices are set by node operators, project deployments, and Flex plan terms instead of one provider-wide rate card.
Commercial status: needs_product_scope (Marketplace pricing)
Free tier: SubQuery access uses project and node-operator scoped Flex plans; no provider-wide free tier is safe to flatten.
Starting price: Prices are set by node operators, project deployments, and Flex plan terms instead of one provider-wide rate card.

Key facts:
- Primary coverage: Decentralized indexing and query services for blockchain application data (source https://subquery.network/)
- Fixture coverage: On-chain state coverage for the Polkadot fixture target (source https://subquery.network/)
Best for candidates:
- Custom blockchain data indexing
- Polkadot and Ethereum application query layers
Not ideal for candidates:
- Raw RPC endpoint hosting
- Market-wide price aggregation
Use case candidates:
- Expose indexed application data through query APIs
- Evaluate decentralized indexer coverage for product backends
Implementation note metadata:
- schema severity medium
- auth severity medium
Quick start metadata: style graphql; language graphql; method POST; path not listed; requires auth yes
Capabilities:
- SubQuery Network on-chain state coverage: indexed only; source evidence documented; auth api_key; integration disposition eligible_free_credentials; coverage polkadot; outputs chain_state_record (chain_slug, address_or_entity, record_type, captured_at)
