Direct answer

Use this page when Claude Code needs supported Claude access.

CorvusLLM can fit Claude Code users who need an independent prepaid access layer for supported Claude models, a clear base URL, current public model slugs, pricing proof, and setup documentation before they send real prompts.

  • Use docs for exact fields and screenshots when the tool changes.
  • Use the model catalog for the current customer-facing slug.
  • Run one small request before repository-wide or production usage.
  • Route private key, order, payment, and balance issues to support.
Setup path

Configure Claude Code without guessing values

Use the Claude Code setup guide, set the CorvusLLM Anthropic-native base URL when the tool supports it, and test with one small command before full repository work.

Install requirement

Install Claude Code or the compatible CLI/tooling you use, sign in or configure it as required by the tool, then add the CorvusLLM key and base URL in the tool settings.

Model family fit

Claude models are usually a fit for coding agents, reasoning-heavy writing, analysis, refactors, and assistant workflows that benefit from Claude-family behavior.

Important caveat

Claude-native clients can use Anthropic-style request shapes, while OpenAI-compatible clients should use the OpenAI-style CorvusLLM endpoint and public model slugs.

base_url = "https://base.corvusllm.com/anthropic" api_key = "YOUR_CORVUSLLM_KEY" model = "claude-haiku-4-5"
Field Use this Why it matters
Where to edit The Claude Code or compatible CLI configuration described in your current tool build. Use the tool-owned settings area instead of hardcoding keys in prompts or visible node text.
Base URL https://base.corvusllm.com/anthropic Use the Anthropic-native route only for tools that support Anthropic-style request shapes.
API key Your CorvusLLM key Keep it in the tool secret store, credentials area, or server environment variables.
Model slug claude-haiku-4-5 or claude-opus-4-5 Use public Claude catalog rows and verify availability before larger runs.
First test One small non-sensitive prompt Confirm endpoint, slug, latency, response format, and billed usage before production or repository-wide context.
Compatibility checklist

Confirm Claude Code can actually use this setup

This table separates a real custom-endpoint setup from cases where the tool version, secret handling, or model field will make the connection fail.

Check Good state Avoid this
Required control Claude Code exposes a custom base URL, custom provider, or compatible API host field. If Claude Code hides endpoint controls, use the docs fallback instead of guessing hidden settings.
Endpoint shape Anthropic-native endpoint support is available and can be set to https://base.corvusllm.com/anthropic. Do not mix Anthropic-native setup values with another request format.
Secret handling The CorvusLLM key is stored in Claude Code settings, credentials, or server environment variables. Do not paste API keys into public repositories, prompts, screenshots, or client-side production code.
Model slug The selected value is a public Claude slug from the model catalog. Do not use private upstream route names, provider-account names, or guessed model aliases.
First request A small non-sensitive prompt succeeds before larger project context, automation, or team rollout. Do not start with private repositories, regulated data, or high-volume automation before a small test.
Model source

Start from live Claude catalog rows

These examples are only starting points. The model catalog and data/models.json are the source of truth for availability, pricing, cache fields, and public slugs.

Troubleshooting before support

Check the common Claude Code failure points first

These checks turn common setup errors into crawlable answers and send private account cases to the right support path only after public checks are exhausted.

Symptom First check Public source
Custom base URL field is missing Confirm your Claude Code version exposes custom provider controls. Claude Code docs
Model not found Use a public Claude slug from the current catalog and avoid hidden aliases. Claude catalog
Authentication or balance error Confirm the delivered CorvusLLM key, account balance, and that the key was not pasted with extra spaces. Troubleshooting
Unexpected cost Estimate input, output, cache read, and cache write before sending large context or loops. Cost calculator
Timeout or provider unavailable Retry a tiny non-streaming prompt, then check customer-facing status before changing credentials. Service Status
Proof and guardrails

Verify price, status, and service boundary first

This is a commercial setup page, not a private account console. Use the supporting pages for exact pricing, operational status, and trust details.

Data handling warning

Do not send sensitive or regulated data through shared API proxies. CorvusLLM forwards prompts to upstream model providers for processing and keeps request metadata for billing, abuse prevention, and support diagnostics.

Common questions

Before using Claude in Claude Code

These answers keep setup pages useful for search, AI answers, and first-time buyers without replacing the exact docs.

Which base URL should Claude Code use for Claude?

Claude Code should use https://base.corvusllm.com/anthropic for this Claude setup path. Check the dedicated docs page when the tool changes its custom-provider settings.

Do I need my own Anthropic account first?

No. This page is for using a CorvusLLM prepaid key as an independent access layer. CorvusLLM is not affiliated with Anthropic, and exact supported rows should be verified in the public catalog.

Can I paste sensitive Claude Code project data into this setup?

Do not send sensitive or regulated data through shared API proxies without a separate risk review. Start with non-sensitive tests and move larger workloads only after checking trust, status, and billing behavior.
