Vayana Enriched API Service (EAS) is one of 3 APIs that [Vayana Network](https://apis.io/providers/vayana-network/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include E-Invoicing, E-Way Bill, GST, Tax Compliance, and Trade Verification. The published artifact set on APIs.io includes API documentation and a getting-started guide.

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.
