Provenance

Provenance Blockchain is a public, proof-of-stake blockchain purpose-built for financial services and the tokenization of real-world assets. Built on the Cosmos SDK with CometBFT consensus, it exposes its functionality through first-party modules including marker (token/marker issuance), metadata (asset registry and the p8e contract execution environment), exchange (on-chain order book), ledger, name, attribute, hold, trigger, and msgfees/flatfees. Applications integrate over the public Cosmos REST (LCD / gRPC-gateway) API at api.provenance.io, gRPC, and Tendermint RPC at rpc.provenance.io, and via first-party SDKs (Go, Kotlin gRPC client, Rust/CosmWasm provwasm bindings, and JavaScript wallet libraries). HASH is the native staking and gas token. The chain, protobuf data model, and SDKs are open source under the provenance-io GitHub organization.

Provenance is listed with 1 API on the APIs.io network. Tagged areas include Company, Blockchain, Financial Services, Tokenization, and Real World Assets.

Provenance’s developer surface includes engineering blog, documentation, API reference, getting-started guide, support, changelog, authentication, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
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)

11 more unmet checks in the Agent Readiness table above.

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

Access Clarity scores 0.0 — up to +20.0 composite points
Contract Quality scores 24.0 — up to +19.0 composite points
Contract Governance scores 4.5 — up to +11.5 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/provenance/apis.yml: open an issue on github.com/api-evangelist/provenance 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
Stablecoins and Tokenization (stablecoin issuers, tokenized assets)	distribution	28.8	-	-
LF Decentralized Trust (Hyperledger) Members and Projects (enterprise blockchain, digital identity, CBDC)	distribution	28.8	-	-
Buf Schema Registry (public Protocol Buffers modules, gRPC / ConnectRPC schema publishers)	distribution	28.8	-	-

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 implemented 1

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.
