Localize Your APIs

Return localized responses from your API. Support Accept-Language headers, handle dynamic content, and keep your backend multilingual without complexity.

The Problem

Common challenges teams face with localization—and how IntlPull solves them.

Hardcoded Messages

Error messages, validation text, and status messages are buried in backend code. Changing a single string requires a code deployment.

No Standard Approach

Every backend has different i18n patterns. Node uses i18next, Go uses go-i18n, Python uses gettext. No unified workflow across services.

Dynamic Content

User-generated content, CMS data, and database strings need localization. Static file approaches don't work for dynamic data.

Microservice Chaos

Each service manages its own translations. Duplicated strings, inconsistent terminology, and sync nightmares across 10+ services.

Accept-Language Complexity

Parsing Accept-Language headers, fallback chains, and quality values is error-prone. Most implementations are incomplete or buggy.

Runtime Overhead

Loading translation files per request adds latency. Caching adds complexity. Performance suffers as languages scale.

The Solution

IntlPull provides everything you need for api localization.

REST API

Fetch translations via simple GET requests. Filter by namespace, key pattern, or platform. Returns JSON ready for your backend.

vs file-based loading

Accept-Language Support

Pass browser headers directly. We parse quality values, handle fallbacks, and return the best match. One line of code.

vs complex parsing logic

Dynamic Interpolation

Translations support ICU MessageFormat. Plurals, gender, and variables work server-side. Return fully formatted strings.

vs basic string replacement

Caching Built-in

ETag and Cache-Control headers on every response. CDN-friendly. Reduces API calls by 90%+ with proper caching.

vs managing cache yourself

Webhooks

Get notified when translations change. Invalidate your cache automatically. Stay in sync without polling.

vs manual cache invalidation

Multi-Service Support

One IntlPull project, multiple services. Shared glossary and translation memory. Consistent terminology everywhere.

vs per-service translation files
