Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API relies heavily on JavaScript-specific patterns and idioms, which may be unfamiliar to developers from other language backgrounds.
v0.1 to v0.2 migration required significant updates to existing codebases due to API refactoring and removal of deprecated methods.
Primary development is in JavaScript, with TypeScript SDK being community-maintained. Lack of official support for other languages makes integration difficult outside the JS ecosystem.
The process of transforming responses from various providers into a consistent format can introduce latency and additional computational load, especially under high throughput scenarios.
