Anthropic
Use your own Anthropic API key with ShopAssist, and the options for EU processing of Claude models.
Create a key
As of October 2026, in the Anthropic Console:
- Open console.anthropic.com → Settings → Workspaces and create a workspace for ShopAssist (optional, for separate limits).
- Open API keys → Create key, choose the workspace and copy the key (
sk-ant-…). - Set up billing under Plans & billing and a spend limit.
Account tier
Any paid API plan. Low tiers have strict rate limits; ShopAssist reports rate_limited when you hit them.

Data location
Data location
Anthropic's API processes data globally or in the US; there's no EU option. For EU processing use Claude on Google Vertex AI (EU) or Amazon Bedrock (EU) under your own cloud account.
Connection test
| Check | Required | What it tests | On failure |
|---|---|---|---|
auth | Yes | The key is accepted (lists models or sends a tiny request) | auth_failed, insufficient_quota, gemini_free_tier, endpoint_blocked, provider_unavailable, model_not_found |
tools | Yes | The model calls a tool with valid arguments and continues after the result | tools_unsupported: the model can't run the shopping tools |
ttft | No (degraded) | The first answer event arrives within 8 seconds | ttft_slow: works, but shoppers wait |
parallel_tools | No | Two tools are called in one step | parallel_tools_unsupported: slightly slower answers |
vision | No | The model names the colour of a test image | vision_unsupported: visual search is off |
context | Self-hosted only | A fact at the start of an 8,000-token prompt is recalled | context_too_small: the endpoint truncates prompts |

Troubleshooting
- 401 /
auth_failed: the key was disabled; create a new one. insufficient_quota: add credit or raise the spend limit in Plans & billing.rate_limited: request a higher tier, or add a fallback.model_not_found: check the model id; older Claude models are retired on Anthropic's schedule.
