Calculate EU VAT amounts by country code and optional category via MPP micropayment.
What it does
This MPP endpoint calculates Value Added Tax (VAT) for EU countries. You supply a monetary amount, an ISO 3166-1 alpha-2 country code, and optionally whether the amount already includes VAT and a VAT category. The endpoint returns the computed VAT breakdown. It is part of a broader VAT service (powered by Abstract API) that also offers VAT number validation and VAT category lookup, each available as separate endpoints on the same host.
Payment is handled via the MPP protocol using the Tempo method (pathUSD on Tempo L2). Each call costs 6000 base units of pathUSD (6 decimals), which equals $0.006 per request. The endpoint accepts POST requests with a JSON body. Note that HEAD/GET probes returned 404, which is expected since this is a POST-only endpoint — the service itself is live and correctly described in the OpenAPI spec.
Upstream documentation is available at Abstract API's VAT docs (https://docs.abstractapi.com/vat) and a Locus-specific LLM-friendly doc at https://beta.paywithlocus.com/mpp/abstract-vat.md. The OpenAPI schema covers request parameters but does not include a response schema, so the exact shape of the response must be inferred from Abstract API's own documentation.
Capabilities
Use cases
- —Calculate VAT on an invoice amount for a specific EU country
- —Determine net and gross prices given a VAT-inclusive amount
- —Compute VAT for a specific product category (e.g., reduced rate goods)
- —Automate EU tax compliance in e-commerce checkout flows
- —Generate tax breakdowns for cross-border EU transactions
Fit
Best for
- —Agents or apps needing per-call EU VAT calculations without API key management
- —E-commerce bots computing tax at checkout for EU customers
- —Financial automation workflows requiring on-demand VAT math
Not for
- —Non-EU tax calculations (US sales tax, GST, etc.)
- —High-volume batch VAT processing where a subscription API would be cheaper
- —VAT number validation (use the sibling /abstract-vat/validate endpoint instead)
Quick start

-H "Content-Type: application/json" \
-d '{"amount": 100, "country_code": "DE"}'Example
Request
{
"amount": 100,
"is_vat_incl": false,
"country_code": "DE",
"vat_category": "standard"
}Endpoint
Quality
OpenAPI schema is present with clear request parameters and pricing info, but no response schema is provided and the crawl yielded no additional documentation. The endpoint is POST-only so the 404 on HEAD/GET is expected, not a liveness failure. Upstream docs exist but were not crawled.
Warnings
- —No response schema defined in the OpenAPI spec — response shape must be inferred from upstream Abstract API docs.
- —HEAD/GET probes returned 404; endpoint is POST-only so liveness could not be directly confirmed via probe.
- —Crawled pages all returned 404 JSON errors; no on-host documentation available.
