Plan API access separately from the chat plan
Anthropic documents Claude Console as the developer platform for API keys and integrations. A paid Claude chat plan does not automatically include that access. Establish which account operates the integration and where consumption is billed. Recheck the actual model and pricing basis in official documentation at setup and record the date.
Treat the key as an operational secret
Supply the key on the server through protected secret management. It belongs neither in public web pages nor in Git, support messages or unprotected configuration. Check which people and services can use it and how to revoke it when compromise is suspected. Consumption monitoring helps detect unexpected use; a hidden form field does not protect a key.
Measure cost per accepted output
A test workflow can turn an approved enquiry into a fixed output schema. Record consumption, failed attempts and rework until acceptance. Add hosting, other APIs and support. Separate measurements from assumptions in the plan. Only then can a sensible consumption boundary be set for higher request volume.
Decision matrix
| Decision point | Proceed when | Stop when |
|---|---|---|
| Cost assumptions | Documented: key management, models, tokens, caching, limits and monitoring. | Scope, data or accountability remains unresolved. |
| Measurement baseline | A bounded test records the model, observed usage and corresponding dated pricing baseline. It also checks that the API key appears neither in the client nor in the repository or unnecessary logs. | There is only an unevaluated demo without acceptance evidence. |
| Budget decision | Owner, approval, fallback and next review date are defined. | Avoid: storing API keys in clients or repositories. While key management remains unresolved or usage is merely assumed, there is no basis for an approved integration with a reliable budget. |
Keep it verifiable
