Blockskye

Blockskye is an enterprise travel management and payments platform for large corporate travel programs, founded in 2017 and headquartered in New York. It combines a consumer-grade online booking tool sourced through direct supplier and NDC connectivity, BMAX direct settlement that wires a customer's ERP straight to travel suppliers so booked travel bypasses corporate cards and expense reports, B360 for capturing personal co-brand card loyalty on business trips while holding policy compliance, and real-time reporting across every booking channel, with transactions recorded to a tamper-resistant distributed ledger. Blockskye delivers an end-to-end corporate travel solution in partnership with KAYAK for Business. The platform is sold and operated as an enterprise service: the booking, servicing and settlement application runs at horizon.blockskye.com behind a customer login and the knowledge base sits behind a Freshworks OAuth login. Blockskye operates a live production API host at api.blockskye.com but publishes no public developer portal, API reference, or machine-readable API contract.

Blockskye publishes 1 API on the APIs.io network. Tagged areas include Travel, Corporate Travel, Travel Management, Payments, and Settlement.

Blockskye’s developer surface includes engineering blog, support, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments 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.
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/.

  detail: Blockskye runs a live production API at api.blockskye.com whose /health endpoint answers 200 anonymously, but the
    only Blockskye documentation that exists sits in a Freshworks-backed knowledge base where /support/solutions chains 302
    to /support/home to /support/login and out to a blockskye.myfreshworks.com OAuth authorize URL, so the reference is reachable
    only by an existing customer tenant.
