Free public APIs

Public routes expect the console client header from the web UI. Prefer the hosted console, calculator, or documented client for production calls.

GET /api/v1/public/packs — all country packs
GET /api/v1/public/packs/:country — pack + rate registry
GET /api/v1/public/rates/status — rates as-of + AI sync status
GET /api/v1/public/rates/changed?since=YYYY-MM-DD
POST /api/v1/public/quote — live tax calculate
POST /api/v1/public/verify/exhaust — calculate-and-forget history verify

Example quote

curl -sS -X POST https://tax.xero-sphere-ai.com/api/v1/public/quote \
  -H "Content-Type: application/json" \
  -H "X-XeroTax-Client: xerotax-web" \
  -d '{"country":"PK","currency":"PKR","tax_mode":"exclusive","lines":[{"amount_cents":10000,"qty":1}]}'

Daily official rates (secure AI agent)

A secure AI agent fetches allowlisted government domains only, proposes rates into the rate registry (verified at high confidence, else pending review). Host cron: npm run rates:refresh. Provider credentials stay on the host — never in the browser.

Free exhaust sync — calculate and forget

Large history sync is free within tier limits. POST /api/v1/public/verify/exhaust quotes every invoice in memory and returns counters (plus itemized rows for your own CSV export). No invoice payloads are stored on our servers.

curl -sS -X POST https://tax.xero-sphere-ai.com/api/v1/public/verify/exhaust \
  -H "Content-Type: application/json" \
  -H "X-XeroTax-Client: xerotax-web" \
  -d '{"pack_code":"PK","invoices":[{"invoice_no":"INV-1","total_amount":1000,"tax_amount_cents":18000}]}'

Connect POS

“Scan” means auto-detect unique invoice fields from history JSON — not a camera QR. Flow:

In the shop app: Sales History → Create API key → copy xst_… (shown once).
In Xero Sphere AI Tax console → Connect → paste shop base URL + key → Test fetch.
Auto-scan fields → verify history in this tab → export CSV before you leave.

Call GET {shop}/api/integrations/sales with x-api-key or Bearer xst_…. Connections are ephemeral in your browser — not saved on tax servers.
