Securitize

Securitize is a tokenization platform and SEC-registered financial services group that issues, manages, and services digital securities representing real-world assets — tokenized U.S. Treasuries, private credit, private equity, funds, and equities — for asset managers including BlackRock (BUIDL), Apollo (ACRED), Hamilton Lane, KKR, and VanEck (VBILL). The company operates a registered transfer agent, broker-dealer (Securitize Markets), alternative trading system, fund administration business, and an EU-approved investment firm, and it publishes three developer-facing APIs: a Domain API covering the full securities lifecycle (investor onboarding, KYC/KYB, accreditation, fundraising, issuance, token wallets, blockchain transactions, snapshots, and holder records), a Connect API that acts as an OAuth provider for Securitize iD single sign-on and verified-identity sharing, and a Webhook API for real-time investor event delivery. Securitize also runs a public, unauthenticated MCP server that exposes its tokenized-asset catalog to AI agents.

Securitize publishes 5 APIs on the APIs.io network, including APAC API, Domains API, Health Check API, and 2 more. Tagged areas include tokenization, digital-securities, real-world-assets, capital-markets, and fund-administration.

The Securitize catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Securitize’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 21 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data 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/. This rating is computed from github.com/api-evangelist/securitize: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
