Endpoint families
OpenAPI lists account, contract, coretime, governance, reliability, revenue, staking, summary, transaction, treasury, validator, and XCM metrics. Source
Auth model
All endpoints require a DotLake API key used as a Bearer token after wallet-based registration. Source
Freshness note
The Polkadot forum announcement describes daily updates for the API data coverage. Source
Commercial fact
No public price, quota, or rate-limit schedule is listed in the OpenAPI description; users must sign in with a Polkadot wallet to obtain an API key. Source
PubFi status
PubFi Discovery tracks DotLake API as a public source profile; PubFi does not expose a production DotLake gateway route in the current gateway readiness catalog. Source

Best fit and tradeoffs

Best for

  • Pre-aggregated Polkadot ecosystem metrics
  • Governance, staking, treasury, and XCM analytics workflows
  • Backend dashboards that can store an API key server-side
  • They want official Polkadot ecosystem metrics without operating their own indexing or analytics pipeline first.
  • They need daily or monthly time-series metrics for governance, staking, treasury, XCM, validator, account, contract, or network-health analysis.
  • They are building backend dashboards, research tools, or analytics services where a server-side API key is acceptable.

Watchouts

  • Anonymous browser-only client calls
  • Low-level block, account, or extrinsic exploration that needs raw event granularity
  • Generic EVM RPC workloads
  • DotLake requires wallet-based registration and API-key use, so browser-only anonymous clients need a backend wrapper rather than direct public calls.
  • The first public positioning emphasizes pre-aggregated, high-level metrics rather than low-level block, event, account, or extrinsic exploration.
  • Public docs do not list exact plan prices, quotas, or rate-limit numbers, so commercial and throughput assumptions need revalidation before production use.

Why teams choose it

DotLake API is a Parity Data REST API for pre-aggregated Polkadot, Kusama, and Substrate ecosystem metrics. The official announcement frames it as a way to access time-series metrics such as uptime, TPS, fees, staking, governance, treasury, stablecoin, validator, contract, and XCM data without running custom indexer infrastructure.

For PubFi readers, the important distinction is that DotLake is an official aggregated metrics API rather than a full explorer API or a custom indexing framework. It can be a strong fit for dashboards, research, and analytics workflows that can keep an API key server-side, but it should not be presented as a live PubFi gateway provider until a separate gateway integration exists.

PubFi gateway status

PubFi gateway not routeable yet

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.

  • 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.

Implementation notes

Auth

Medium

Treat DotLake API-key issuance and wallet sign-in as part of the integration path; keep any key server-side and do not describe the source as anonymous public browser access.

Coverage

Medium

Map DotLake to pre-aggregated metric workflows such as governance, staking, treasury, XCM, accounts, contracts, reliability, revenue, and summary metrics rather than to raw explorer-style record lookup.

Freshness

Medium

Use the forum announcement daily-update claim as source evidence, but keep production freshness expectations tied to endpoint-level validation before promising operational SLAs.

Claim Safety

Medium

Keep DotLake as a public source profile until a separate PubFi gateway readiness entry and provider credential path are implemented.

Use case candidates

  • Build Polkadot ecosystem health dashboards from daily and monthly metrics
  • Track OpenGov, treasury, staking, and validator metrics without running a custom indexer
  • Compare official aggregated metrics against explorer-style or custom-indexing sources

Comparison snapshot

DotLake is closest to Subscan when the buyer wants ready-made Polkadot ecosystem data, but the product shape differs: DotLake emphasizes official pre-aggregated metrics and time series, while Subscan emphasizes explorer-style indexed account, extrinsic, governance, staking, and asset reads. SubSquid and SubQuery remain better fits when the team needs custom indexing and query-control rather than a fixed metrics API.

PubFi friction reduction

Auth

Source friction
The official OpenAPI description says all endpoints require a valid API key, and the forum announcement describes SIWS wallet registration before key creation.
PubFi relief
Discovery labels DotLake as a source profile and exposes the auth requirement before a team treats the API as browser-callable or PubFi-routable.

Coverage

Source friction
The DotLake OpenAPI and forum announcement list metric families across governance, staking, treasury, reliability, transactions, validators, accounts, contracts, and XCM.
PubFi relief
Discovery places DotLake in the Polkadot on-chain-state and governance shortlists while preserving alternatives for explorer-style and custom-indexing workloads.

FAQ

What is DotLake API used for?

DotLake API is a source for pre-aggregated Polkadot, Kusama, and Substrate ecosystem metrics such as uptime, TPS, fees, staking, governance, treasury, account, contract, and XCM data.

Does DotLake API require authentication?

Yes. The official OpenAPI description says all endpoints require a valid API key used as a Bearer token, with API-key issuance after Polkadot wallet sign-in.

Is DotLake API available through PubFi gateway?

No current PubFi gateway readiness entry exists for DotLake API. Discovery lists it as a public source profile and integration candidate, not as a live PubFi-routed provider.
