Vayana Network

Vayana (legal entity Vay Network Services Pvt. Ltd., founded 2016, headquartered in Pune, India) operates India's trade credit infrastructure network, connecting buyers, sellers, banks and NBFCs across supply chains, and is a GSTN-authorized GST Suvidha Provider (GSP). Its developer surface spans three published programs: Vayana Atlas, an API marketplace for trade and compliance covering identity/business verification (PAN, GSTIN, Aadhaar, MCA, Udyam, EPF, bank account, vehicle, voter ID) alongside GST e-invoicing and E-Way Bill operations; the Enriched API Service (EAS), a higher-level wrapper adding bulk processing, PDF generation and long-running task handling over the GSTN, NIC E-Way Bill and IRP e-invoicing peers; and Vayana GSP Pass-Through API Service (PAS), a thin encrypted gateway to the same government ecosystems. Authentication across all three runs through Vayana's own SSO service (internally "theodore"), and sensitive values are RSA/AES encrypted in transit above TLS.

Vayana Network publishes 6 API contracts indexed on the APIs.io network, including Authorization Suite API, Compliance Suite API, Support Suite API, and 3 more. Tagged areas include Company, Trade Finance, Supply Chain Finance, Tax Compliance, and E-Invoicing.

The Vayana Network catalog on APIs.io includes 1 Spectral governance ruleset.

Vayana Network’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, engineering blog, authentication, and 22 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 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
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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
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)

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
E-invoicing and Tax Compliance (certified operators)	undeclared	-	-	-
Biometrics Testing (biometric recognition vendors, identity verification depth)	undeclared	-	-	-
India RBI Regulated Entities (payment system operators, payment aggregators, PPI issuers, NBFCs, AAs)	undeclared	-	-	-
India RBI / SEBI Registers (SEBI intermediaries, RBI NBFCs, payment aggregators, PPI issuers, AAs)	undeclared	-	-	-

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.

  description: The Enriched API Service ("Flynn") is Vayana GSP's higher-level API suite over the three GSTN peers — the GST
    Returns portal, the NIC E-Way Bill portal and the IRP e-invoicing portal. "Basic" routes are thin wrappers that handle
    auth-token management and payload encryption/decryption only; "enriched" routes add bulk processing, PDF and JSON generation,
    email notification, file download and asynchronous long-running task handling. Routes follow the pattern /{module}/{sub-module}/{version}
    where module is basic or enriched and sub-module is gstn, ewb or einv. A Trade Verification Service verifies e-invoices,
    signed QR codes, scanned QR codes, e-invoice PDFs and invoices against their E-Way Bills.
