BlockVision

BlockVision is a Web3 data infrastructure provider offering multi-chain node, indexing, and on-chain data-retrieval APIs for developers building decentralized applications. Its stack includes an Indexing API service (real-time account, coin/token, NFT, DeFi, DEX-market and smart-contract data across Sui, Monad, Ethereum, Arbitrum, BNB Chain, Optimism and Polygon), an RPC Node service (AceNode) with geo-distributed low-latency and archive access, a gRPC endpoint for Sui, and Explorer-as-a-Service (branded block explorers such as SuiVision and BBScan). Requests to the Data API (api.blockvision.org, versioned under /v2) are authenticated with an x-api-key header and metered in Compute Units. Originally added to the API Evangelist network as a portfolio company of Qiming, this profile has been enriched from BlockVision's public developer surface.

BlockVision publishes 2 API contracts indexed on the APIs.io network: Monad API and Sui API. Tagged areas include Company, Blockchain, Web3, Data Infrastructure, and Sui.

The BlockVision catalog on APIs.io includes 1 Spectral governance ruleset.

BlockVision’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/blockvision: open an issue to ask a question, or submit a pull request to add artifacts.
