BlockVigil

BlockVigil was a blockchain / Web3 developer platform company, surfaced as a portfolio company of 500 Global and added to the API Evangelist network. As of the enrichment pass on 2026-07-18, the company's website (https://blockvigil.com) publishes only a wind-down notice stating that "BlockVigil has concluded its active service offerings," directing remaining custom-contract customers to their designated representative. No developer portal, API documentation, OpenAPI, SDKs, or well-known/ metadata are published; this profile therefore captures only live domain-security posture and the discontinuation status.

BlockVigil is profiled on the APIs.io network. Tagged areas include Company, Blockchain, Web3, Discontinued, and Portfolio.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/blockvigil: open an issue to ask a question, or submit a pull request to add artifacts.
