CURREXX can stay live and useful without paid provider APIs by using reference rates and manual quote comparison. Automatic provider pricing should be added only after authorized API access, data-display rights and compliance review are ready.
Reference rates are not provider quotes
A reference-rate API can show daily currency benchmarks, but it usually does not include a provider-specific transfer fee, payout method, delivery speed, quote expiry or public display permission for provider prices.
What a live quote feed must provide
A useful provider feed should return the offered exchange rate, fixed fee, percentage fee, final recipient amount, quote validity, supported countries, payout method and disclosure links for the exact corridor and amount.
Why permission matters
Provider pricing, brand names and quote data can be governed by API terms, commercial agreements, affiliate rules or regulatory obligations. CURREXX should not scrape or republish prices without clear permission.
Safe Hostinger architecture
API keys should stay server-side in private settings, never in browser JavaScript. A PHP adapter can fetch quotes, normalize fields, cache short-lived responses, log failures and fall back to manual comparison if a source is unavailable.
Recommended Phase 3 path
Keep the current manual scorecard as the public comparison tool, then add provider adapters one by one after credentials, display rights, rate limits, quote expiry rules and support responsibilities are confirmed.
Quick checklist
- Separate reference-rate content from provider-specific quote content.
- Confirm API access, commercial permission and public display rights.
- Capture rate, fixed fee, variable fee, recipient amount and quote expiry.
- Store API credentials only in private server-side settings.
- Use caching, fallback messaging and monitoring before public launch.
- Review privacy, compliance and provider disclosure requirements.
FAQs
Can CURREXX compare live providers without paid APIs?
Not safely at a professional level. Free reference-rate APIs can power benchmarks, but provider-specific live quotes usually need authorized access, display rights and fee coverage.
Is Frankfurter enough for live provider comparison?
Frankfurter is useful for reference exchange rates, but it does not provide provider-specific transfer fees, payout methods, quote expiry or brand-approved provider quotes.
Should API keys be added to front-end JavaScript?
No. Provider API credentials should stay on the server side in private settings or environment variables, with browser requests going through a controlled backend endpoint.
What should CURREXX do before adding automatic provider quotes?
Confirm source permission, normalize the quote schema, add short-lived caching, document fallbacks, review compliance and test accuracy across priority corridors.
