Crypto API Fixer
Auto-repair middleware for crypto trading bots.
Fixes API errors silently in <2ms — before your bot loses money.
One middleware. Ten error types. Zero headaches.
Why It Exists
Crypto trading bots break at 3 AM because of:
- Rate limits (429/503)
- Stale/outdated data
- Broken JSON schemas
- Auth failures
- Price mismatches
- Endpoint downtime
- And more...
You sleep. Your bot freezes. You lose money.
Crypto API Fixer fixes it automatically.
