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 7 API contracts indexed on the APIs.io network, including APAC API, Domains API, Health Check API, and 4 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 and 1 Spectral governance ruleset.
Securitize’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, authentication, and 22 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.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 75 points between them,
because the conditional facet above carries the other
25. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 75% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling+7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples+7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
