Routes and billing

This page is the public RouteKit launch-support disclosure. The maintainer mirror lives at docs/routekit-routes-and-billing.md.

The current first-launch contract contains six routes, all Planned Supported until L06 closes. Historical L06 evidence references RouteKit 0.8.0 revision dad16c53c0e083a51d41df59149a21964d27cc12 (2026-07-22) and the end-to-end matrix. That immutable report contains a historical Cursor row that is not a current support claim. See client compatibility for the exact supported client builds and separate 2026-08-01 Cursor evidence.

Shared contract

• A requested namespaced model never falls through to another provider.
• API routes have no RouteKit account-pool or cross-provider failover.
• Subscription pools rotate only among eligible accounts of the same kind.
• RouteKit makes no unlimited-use claim. Provider terms and quotas always apply.
• Portable message and tool history can cross compatible routes. Opaque encrypted reasoning is retained only for its originating provider and native model.

Inspect a live route with:

routekit models info <provider/model>

The response includes namespaced and native model IDs, provider, account class, billing mode (api-key / metered-api, subscription / subscription), and capabilities. Unknown models fail. Credentials are never returned. See also route explanation evidence.

OpenAI API

• Status and evidence: Planned Supported until L06 closes. L06 Pass for openai/gpt-5.5, RouteKit 0.8.0 / 2026-07-22. Evidence.
• Credential: User-owned OPENAI_API_KEY; optional OPENAI_BASE_URL.
• Billing: Metered API-key route; OpenAI determines charges.
• Egress and aggregator: Direct to api.openai.com unless overridden. No aggregator.
• Quota and failover: Provider errors return to the caller; no account pool and no silent cross-provider fallback.
• Protocol and limitations: OpenAI Chat Completions and native Responses. Direct OpenAI API routes keep /v1/responses requests on the native Responses endpoint, preserving tools, reasoning, streaming, continuation IDs, and opaque response items without translating through Chat Completions.
• Unlimited use: RouteKit makes no unlimited-use claim.

Anthropic API

• Status and evidence: Planned Supported until L06 closes. L06 Pass for anthropic/claude-sonnet-4-6, RouteKit 0.8.0 / 2026-07-22. Evidence.
• Credential: User-owned ANTHROPIC_API_KEY; optional ANTHROPIC_BASE_URL. RouteKit does not currently use ANTHROPIC_AUTH_TOKEN for provider requests.
• Billing: Metered API-key route; Anthropic determines charges.
• Egress and aggregator: Direct to api.anthropic.com by default. No aggregator.
• Quota and failover: Provider errors return to the caller; no account pool.
• Protocol and limitations: Native Messages with streaming, tools, and thinking where supported.
• Unlimited use: RouteKit makes no unlimited-use claim.

Amazon Bedrock

• Status and evidence: Planned Supported until L06 closes. L06 pending — authorized-operator qualification, RouteKit 0.8.0 / 2026-07-22. Evidence.
• Credential: Operator-owned AWS SDK default-chain identity and region; see the AWS Bedrock guide.
• Billing: Direct AWS Bedrock Runtime route; AWS determines charges and credits are account-specific.
• Egress and aggregator: Direct to AWS Bedrock in the configured account and region. No aggregator, though cross-region inference profiles can route to AWS destination regions.
• Quota and failover: AWS model access, IAM, service quotas, and throttling apply. Provider errors return to the caller; no silent cross-provider fallback.
• Protocol and limitations: Live model and inference-profile discovery plus Bedrock Runtime invocation. Availability, streaming, tools, and reasoning vary by model and region.
• Unlimited use: RouteKit makes no unlimited-use claim.

OpenRouter API

• Status and evidence: Planned Supported until L06 closes. L06 Pass for openrouter/openai/gpt-4o-mini, RouteKit 0.8.0 / 2026-07-22. Evidence.
• Credential: User-owned OPENROUTER_API_KEY.
• Billing: OpenRouter API-key/credit route; OpenRouter determines charges.
• Egress and aggregator: OpenRouter is an aggregator. RouteKit sends prompts, code, tool data, and model requests to openrouter.ai, which forwards them to an upstream provider under OpenRouter routing.
• Quota and failover: No RouteKit account pool or silent direct-provider switch.
• Protocol and limitations: OpenAI Chat Completions; tools and streaming depend on OpenRouter and the upstream model.
• Unlimited use: RouteKit makes no unlimited-use claim.

Codex subscription

• Status and evidence: Planned Supported until L06 closes. L06 Fail — account-unavailable, RouteKit 0.8.0 / 2026-07-22. Evidence.
• Credential: User-owned Codex OAuth credential from accounts login codex.
• Billing: Subscription plan usage determined by the provider.
• Egress and aggregator: Relays to chatgpt.com/backend-api/codex with the enrolled OAuth credential; never OPENAI_API_KEY. No third-party aggregator.
• Quota and failover: Rotates eligible Codex accounts only. Before response output is committed, credential-scoped authentication failures can trigger coalesced refresh and reroute to a healthy account in the same pool. Exhaustion never invokes a paid OpenAI API-key route.
• Protocol and limitations: OpenAI Responses with streaming and tools. The exact supported Codex CLI build is 0.146.0; see client compatibility.
• Unlimited use: RouteKit makes no unlimited-use claim.

Claude Code subscription

• Status and evidence: Planned Supported until L06 closes. L06 Fail — account-unavailable, RouteKit 0.8.0 / 2026-07-22. Evidence.
• Credential: User-owned Claude Code OAuth credential from accounts login claude-code.
• Billing: Subscription plan usage determined by Anthropic.
• Egress and aggregator: Relays to Anthropic with the enrolled OAuth credential; never ANTHROPIC_API_KEY. No third-party aggregator.
• Quota and failover: Same-kind eligible-account rotation. Before response output is committed, credential-scoped authentication failures can trigger coalesced refresh and reroute within that pool. Exhaustion never invokes a paid Anthropic API-key route.
• Protocol and limitations: Native Anthropic Messages relay with streaming and tools. The exact supported Claude Code builds are 2.1.216 and 2.1.220; see client compatibility.
• Unlimited use: RouteKit makes no unlimited-use claim.

Not offered client surfaces

Cursor Desktop is not part of the current launch contract. On 2026-08-01, Cursor Desktop 3.12.30 rejected RouteKit model names before sending a gateway request. See the sanitized qualification record. The retained /v1/cursor adapter is an internal compatibility surface, not a support declaration. cursor-agent is also not offered because it expects Cursor's backend/ACP protocol rather than an OpenAI-compatible gateway.

Qualification evidence

Public route status stays conditional until L06 closes. The durable evidence map is routekit-l06-evidence.md. Its Cursor row is retained as historical evidence and is not a current route. Maintainer qualification notes live in routekit-routes-and-billing.md.
