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• Stale/outdated data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.
