SIMBA Chain

SIMBA Chain is a South Bend, Indiana enterprise data company spun out of the University of Notre Dame under U.S. Department of Defense research funding. Its platform — marketed today as SIMBA Trace and built on the SIMBA Blocks / Build / Ensure / Insights product suite — turns products, components, assets, credentials and organizations into tamper-evident, cryptographically sealed records on permissioned blockchains (Ethereum, Hyperledger Fabric, Polygon, Quorum) for supply-chain visibility, traceability, digital thread and EU Digital Product Passport compliance. Developers deploy Solidity or Chaincode smart contracts through SIMBA Build, which auto-generates a REST API (OpenAPI + SwaggerUI) per application, plus a GraphQL query surface, event/notification subscriptions, and DID/Verifiable Credential issuance through SIMBA Ensure. Customers include the U.S. Air Force, Boeing, the Defense Logistics Agency and the Australian Defence Force.

SIMBA Chain publishes 19 API contracts indexed on the APIs.io network, including Authentication API, Bulk Users Import Requests API, Device App Admin API, and 16 more. Tagged areas include Company, Blockchain, Supply Chain, Traceability, and Digital Product Passport.

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

SIMBA Chain’s developer surface includes documentation, API reference, getting-started guide, quickstart, support, engineering blog, changelog, and 29 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector 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 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.

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/.

Agent readiness — checks not met, largest first (exact, from this profile):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

5 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 47.1 — up to +13.2 composite points
Access Clarity scores 34.2 — up to +13.2 composite points
Contract Governance scores 18.2 — up to +9.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/simba-chain/apis.yml: open an issue on github.com/api-evangelist/simba-chain to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

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.

Market	Position	Depth	Registered MCP server	Declares compatibility
Government Cloud (FedRAMP, GovRAMP, G-Cloud)	standard	36.4	-	-
Electronics Recycling & Circular Economy (e-waste, battery value chain, circularity networks)	standard	36.4	-	-
LF Decentralized Trust (Hyperledger) Members and Projects (enterprise blockchain, digital identity, CBDC)	standard	36.4	-	-

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.
