Net Amount is a sales tax rate API built for developers, AI agents, and platforms. Its core capability is converting an address or latitude/longitude coordinates into jurisdiction-level sales tax results. It positions itself as a βsales tax rate & jurisdiction lookup APIβ and makes clear that it is not filing software. That makes it better suited as a tax-rate lookup component for checkout flows, quoting systems, internal tools, or platform infrastructure, rather than a complete tax compliance or filing system.
Functionally, it supports address-based lookup, coordinate-based lookup, combined sales and use tax totals, jurisdiction breakdowns, address validation, and a Calculate API. Responses include standardized geocoding results, matched jurisdictions, totals grouped by tax type, and timing metadata. More advanced features include bulk lookup, historical tax rates since 2018, asOfDate queries for a specified date, usage analytics, and alerts. The documentation notes that address lookup is backed by Geocode Earth or Geoapify-backed geocoding.
From an integration perspective, the product is primarily offered as an HTTP API, with examples using curl. The /v1/tax/* endpoints require an API key after billing is enabled. The main materials do not disclose official SDKs, supported programming languages, open-source status, or a clear self-hosting option. The documentation references localhost:8787 as a local Base URL, but the production Base URL and support contact information have yet to be made public, suggesting the service may still be in a refinement stage before a full public API launch.
Pricing is very transparent: Free includes 250 queries per month; Starter is $19/month for 3,000 queries; Developer is $49/month for 15,000 queries; Growth is $99/month for 50,000 queries; Scale is $249/month for 200,000 queries; Platform is $499/month for 500,000 queries; and Enterprise starts from $999/month. Each tier has request rate limits and uses a hard cap: once the monthly quota is reached, the API returns 429 and no usage-based overage fees are charged. The upside is predictable budgeting; the downside is that traffic spikes require upgrading in advance. Annual billing saves 20%.
Its strengths are a focused feature set, transparent pricing, a free tier suitable for prototyping, and support for jurisdiction-level details and historical tax rates. Its limitations are that its scope is relatively narrow and does not cover tax filing; historical rates only go back to 2018 and are available only on Scale and higher plans; and there is limited information about production integration, SDKs, payment methods, and self-hosting.
It is suitable for ecommerce checkout, custom shopping carts, SaaS quoting systems, ERPs, marketplaces, and multi-tenant platforms that need real-time tax-rate lookup or pre-transaction estimates. If you need full filing, tax compliance workflows, or a more mature ecosystem, it is worth comparing TaxJar, Avalara AvaTax, Stripe Tax, Vertex, Sovos, and similar providers.
The main materials do not provide information about access from mainland China, payment methods, or localization, so availability should be treated as unknown. Teams in China should first verify API latency, stability, credit card or enterprise payment availability, and whether a proxy or overseas relay deployment is needed.
