Every commercial path is a contact form: the Atlas marketplace routes to https://atlas.vayana.com/contact-us/, and the GSP product page routes to an enquiry form. Two facts are published that bear on cost, and they are recorded because they are the only concrete billing signals in the developer surface: the sandbox environment (solo.enriched-api.vayana.com) is a test system against GSTN Sandbox / NIC pre-prod, while the production environment (live.enriched-api.vayana.com) "uses live GSTN infrastructure with all API calls being chargeable" — so billing is per API call, metered in production only; and Vayana ships a first-party metering endpoint, Get Api Usage, that returns a caller's own usage report for any 90-day span within the last 18 months, optionally emailed as CSV. A buyer can therefore measure consumption precisely but cannot price it without talking to sales. billing_signals: - signal: per-call charging in production detail: Production calls are chargeable; sandbox calls are not. source: https://docs.enriched-api.vayana.com/1s2-integrating/ - signal: self-service usage metering operation: GET /enriched/{flynn-version}/api-usage/report?from-date={fromDate}&to-date={toDate}&email={email} detail: Max 90 days per call, 18 months of history, optional CSV delivery to the logged-in email. source: https://docs.enriched-api.vayana.com/routes/enriched/Get-Api-Usage/get-api-usage-vone-oh/ plans: []
