[Bug] Anthropic API Error: credit_balance_too_low despite sufficient account credits

[ndconsulting]

Bug Description
Anthropic API billing issue — workspace shows $105 credit balance ($50 paid invoice cleared today + $50 grant + $5
free), no spend limit blocking ($0 of $55 monthly used), Tier 2 rate limits, single workspace/single key. API
returns 400 credit_balance_too_low on EVERY request including a max_tokens=1 smoke test. Request IDs:
req_011CaYs3ZD1aEGS8FxHHjWaN, req_011CaYqkfQz5LPxgH8e5HWPj. Persisted across two API keys and 90+ minutes after
invoice settlement. Tier-1 support confirmed the workspace config looks correct and routed to engineering. Please
investigate the disconnect between visible credit balance and API billing validation.

Hitting the same. Request IDs: req_011CaZMrWi1fpvrPD7TCyJt2 (and others).
Workspace has $35 balance, two paid invoices, $0 spend used, Tier 1 limits,
fresh API key. Direct curl to api.anthropic.com returns same error.

[mhhuda-hoeda]

same problem

[hilascs]

Same!!! That's critical. We've got projects to run.

+1 same symptom on a fresh workspace, rotated multiple api keys and made two payments just in case.

Setup:

• Single Anthropic workspace, single API key
• Funded $20 today (2026-04-29)
• $0 of monthly spend used; spend limits look correct in console
• Tested with two separately-rotated keys — both reject identically

Diagnostic data:

• Request ID: req_011CaZJP8Uh4wJ7F8USUmKwt
• Anthropic-reported org ID: 18a8a9fd-… (masked, available on request)
• /v1/models with the same key: HTTP 200, returns full model list (so auth + workspace are fine)
• /v1/messages with max_tokens: 50 and a 2-token prompt: HTTP 400 credit_balance_too_low

Curl that reproduces it:

curl "https://api.anthropic.com/v1/messages" \
  -H "x-api-key: <fresh key from funded workspace>" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{"model":"claude-sonnet-4-20250514","max_tokens":50,"messages":[{"role":"user","content":"reply ok"}]}'

The rejection is at Anthropic's billing edge (x-envoy-upstream-service-time: 125ms) — never reaches the model. Confirms the OP's "billing apply disconnect" hypothesis.

[crkandrei]

Same issue here. Added $15 in credits but still stuck.

[fernandocardia]

Same here

[Allen161201]

+1 — same issue, blocked since 12h after Stripe settlement.

• Single Default workspace, single active key (fingerprint 4729104f), Tier 1
• Console: $30.00 balance + valid grant (exp May 1, 2027); spend $0.00 of $100/mo
• Banner "To get started... purchase some credits" rendering on the same page as the $30 balance — same billing-vs-auth desync described above
• 400 credit_balance_too_low on every call, including max_tokens=1 smoke test
• Request IDs: req_011CaZEjPiZoTXZCFNDKnZEU, req_011CaZDWucBHCPTJgq9crBBC

Issue seems to be resolved guys. Not sure what exactly changed but my api calls are going through now.

I'm still having the issue.
