Anticipated errors & fixes

401 "authentication_error"

Cause: Key is wrong or was revoked.

Fix: Generate a new key at console.anthropic.com/settings/keys.

429 "rate_limit_error" (inside provider_response)

Cause: You've hit your own Anthropic account's usage tier limit — separate from eConnect's rate limits.

Fix: Wait, or request a higher usage tier from Anthropic.

401 "Unauthorized: Invalid API key."

Cause: Your eConnect Authorization header is missing, malformed, or the key was regenerated/revoked.

Fix: Copy your api_key fresh from the eConnect dashboard and confirm the header reads exactly "Authorization: Bearer <key>".

429 "Too many requests"

Cause: You've exceeded your plan's per-minute rate limit.

Fix: Wait a minute and retry, or upgrade your plan for a higher per-minute limit.

429 "Monthly API limit exceeded"

Cause: You've used your plan's full monthly request allowance.

Fix: Wait for your next billing cycle reset, or upgrade to a plan with a higher monthly limit.
