Open is one of India's leading SMB neobanks, pioneering "connected banking" - a unified business finance platform that layers payments, automated reconciliation, accounting, payroll, expense management, vendor payouts, and GST-compliant invoicing on top of partner-bank current accounts (ICICI, SBI, Axis Bank, Yes Bank and 20+ others). Beyond its SMB application, Open also ships an embedded-finance / Banking-as-a-Service stack branded as Zwitch (zwitch.io), which exposes the same connected-banking primitives - virtual accounts, payouts via NEFT/IMPS/RTGS, UPI collect and intent flows, the Layer hosted payment gateway, beneficiary management, PAN/bank/VPA verification, webhooks, and split settlements - as REST APIs for fintechs and platforms that want to embed account-to-account payments and Indian payment rails into their own products. Open's broader portfolio also includes BankingStack (white-label connected banking for partner banks), the Open Capital lending product, and a suite of e-commerce plugins (WooCommerce, Magento, OpenCart, PrestaShop, CS-Cart, WHMCS) plus PHP, Java, Node.js, iOS, and Android SDKs for the Layer payment gateway.
Open (open.money) publishes 20 API contracts indexed on the APIs.io network, including Accounts API, Constants API, Events API, and 17 more. Tagged areas include Connected Banking, Neobank, Small Business, Embedded Finance, and Banking as a Service.
The Open (open.money) catalog on APIs.io includes 1 Spectral governance ruleset.
Open (open.money)’s developer surface includes support, authentication, documentation, getting-started guide, developer console, signup flow, GitHub presence, and 23 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Banking & Open Finance 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):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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)
Typed Event Surface+6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Agent Skills+5 pts — skills artifact present, graded by who authored it
3 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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.
