How to Use Claude Code With a Cheaper API Key in 2026
Run Claude Code on a cheaper API key: what each route costs, a 5-minute setup with ANTHROPIC_BASE_URL, and when a Claude Max plan is the better deal.
Appearance
TL;DR
The best OpenRouter alternative depends on how you want to pay and host. Sidrune AI is the only gateway on this list priced below official rates, at 30% to 97% off for GPT, Claude, Gemini and Chinese models.
What is OpenRouter, and why do teams look for alternatives?
OpenRouter is a managed API that gives one key access to 500+ models from 80+ providers. It charges each provider's per-token price and adds a platform fee when you buy credits: 5.5% on the Standard plan and 8% on the Business plan, which keeps inference inside the EU or the US.
Bring-your-own-key (BYOK) usage is free up to $25,000 of list-price inference per month on Standard, with a 5% fee on anything above that. In August 2026, Stripe agreed to acquire OpenRouter in a deal reported at more than $7 billion.
Teams usually start comparing options for one of four reasons:
- The fee applies to every top-up. At $20,000 of monthly spend, a 5.5% fee adds $1,100 a month.
- There is no self-hosted option. Every request passes through OpenRouter's infrastructure.
- Data residency costs extra. Keeping inference in one region means paying the 8% Business fee.
- List price is the floor. OpenRouter passes provider prices through, so it never costs less than calling the provider directly.
What should you look for in an OpenRouter alternative?
Five questions separate the options. Answer them before comparing brands.
- How is it priced? Provider price plus a fee, provider price with no markup, or a discount below list price.
- Managed or self-hosted? Self-hosting removes fees but adds servers, upgrades and on-call work.
- Which models does it cover? Check for the exact models you use, including DeepSeek, Kimi and GLM if you need them.
- Which API formats does it accept? Most gateways speak the OpenAI format. Claude Code and other Anthropic clients need the Anthropic format.
- How much control do you get? Budgets, rate limits, logs, guardrails and SSO matter more as a team grows.

1. Sidrune AI
Sidrune AI is a managed API gateway for GPT, Claude, Gemini, Grok, DeepSeek, Kimi, GLM and Qwen, priced below each provider's official list price. It accepts OpenAI, Anthropic and Gemini request formats, so the same account works with the OpenAI SDK, Claude Code and Codex.
Models are sold through routes, and each route has its own price and stability. Prices per 1M tokens, input / output, from Model Plaza on 13 October 2026:
| Model call name | Route | Sidrune AI | Official price |
|---|---|---|---|
gpt-6-astra | GPT-Pro-Premium | $0.60 / $3.00 | $10.00 / $50.00 |
gpt-6-sol | GPT-Pro-Premium | $0.12 / $0.60 | $2.00 / $10.00 |
gpt-5.6-sol | GPT-Pro-Premium | $0.30 / $1.80 | $5.00 / $30.00 |
claude-opus-5-5 | Claude-Max-LIMIT INJECT | $0.88 / $4.40 | $4.00 / $20.00 |
claude-fable-5-1 | Claude-Max-LIMIT INJECT | $2.64 / $13.20 | $10.00 / $50.00 |
claude-sonnet-5 | Claude-Max-LIMIT INJECT | $0.44 / $2.20 | $2.00 / $10.00 |
deepseek-v4-pro | Deepseek | $0.25 / $0.75 | $0.50 / $1.50 |
qwen-3.8-max | Qwen | $1.00 / $3.00 | $2.00 / $6.00 |
kimi-k3 | Kimi | $1.80 / $9.00 | $3.00 / $15.00 |
glm-5.3 | GLM | $0.84 / $2.64 | $1.40 / $4.40 |
gemini-3.1-pro | Gemini-Reverse | $0.12 / $0.72 | $2.00 / $12.00 |
grok-4.7 | Grok-Reverse | $0.08 / $0.24 | $2.00 / $6.00 |
Grok is 96% below official prices, Gemini and GPT (on the GPT-Pro-Premium route) 94%, DeepSeek and Qwen 50%, Kimi and GLM 40%. GPT has six routes, from 97% below official price on the cheapest, least stable route to 60% below on official OpenAI and Azure keys. Claude has twelve routes, from 30% below on official Anthropic keys to 95% below on the Kiro route, which Model Plaza rates lowest for intelligence. The Claude-Max route in the table works with any client and is billed on a base price 20% above list for Fable models; a Claude Code-only route is 82% below list on Opus and Sonnet.
Best for: developers and teams that want frontier and Chinese models at below-list prices without running infrastructure.
Pros:
- Prices sit below the provider's list price, where most gateways sit at or above it.
- DeepSeek, Kimi and GLM are available next to GPT, Claude and Gemini on one account.
- Anthropic-format support means Claude Code works without a translation layer.
- Model IQ is public: it tracks model quality with a fixed benchmark set, and community ratings only come from users who have spent on that model family.
- Pay as you go or a subscription plan.
Cons:
- Managed only. There is no self-hosted version.
- Each API key belongs to one route with one request format (OpenAI, Anthropic or Gemini), so using GPT and Claude together means separate keys. On OpenRouter one key reaches every model.
- The cheapest routes run on shared account pools: they can slow down or lose quality at peak hours.
- Some routes work only with specific clients: the cheapest Claude Max route runs only inside Claude Code.
Pricing: pay as you go per token, or a plan for predictable usage. Full catalog in Model Plaza.
2. LiteLLM
LiteLLM is an MIT-licensed open-source gateway that puts 140+ LLM providers behind one API and one authentication layer. The free version includes virtual keys, budgets, teams, load balancing and guardrails. The enterprise tier adds SSO, JWT authentication, audit logs and SLAs.
Best for: platform teams that want full control and no gateway fee.
Pros: no markup, the widest provider coverage among self-hosted options, and a large community.
Cons: you run it yourself, including the database, upgrades and scaling. Enterprise controls sit behind the paid tier.
Pricing: free to self-host. You pay providers directly, plus your own infrastructure costs.
3. Requesty
Requesty is a managed LLM router with 600+ models, caching, fallbacks and EU data residency. It adds a flat 5% to the provider's token price, and bring-your-own-key is included.
Best for: teams that want an OpenRouter-style managed router with data kept in the EU.
Pros: simple flat pricing, a large catalog, EU residency included without a separate tier.
Cons: the 5% applies to all usage, and there is no self-hosted option.
Pricing: free tier of 200 requests a day on free models, then pay as you go at provider price plus 5%.
4. Vercel AI Gateway
Vercel AI Gateway gives a single endpoint to hundreds of models and charges the provider's list price with no markup. It fits naturally into projects built with the Vercel AI SDK.
Best for: teams that already deploy on Vercel.
Pros: no platform fee on tokens, and $5 of free credits every month to experiment.
Cons: it is tied to a Vercel account. Zero data retention and provider allowlists are billed as add-ons at $0.10 per 1,000 requests. The free monthly credit ends permanently after your first credit purchase.
Pricing: provider list price, pay as you go.
5. Cloudflare AI Gateway
Cloudflare AI Gateway sits in front of your model providers and adds caching, rate limiting and analytics. The core features are free on every Cloudflare plan.
Best for: teams already on Cloudflare that want caching and usage analytics with no gateway fee.
Pros: no per-call gateway fee, and caching can cut repeat-request costs.
Cons: most setups use your own provider API keys, so billing stays split across providers. The free plan stores 100,000 logs a month.
Pricing: core features free. The Workers Paid plan starts at $5 a month and raises the log limit to 1,000,000.
6. Prisma AIRS AI Gateway (formerly Portkey)
Palo Alto Networks completed its acquisition of Portkey on 29 May 2026, and Portkey is now the AI gateway inside Prisma AIRS. It offers access to 1,600+ LLMs with guardrails, observability and budget controls.
Best for: enterprises that want the AI gateway and AI security under one vendor.
Pros: strong governance and security features, backed by a large security company.
Cons: the product direction is now security-first, and larger deployments go through enterprise sales.
Pricing: free tier to start. Enterprise pricing through Palo Alto Networks sales.
7. Bifrost
Bifrost is an open-source gateway from Maxim AI, written in Go and released under Apache 2.0. It supports 23+ providers with failover, load balancing and semantic caching. In Maxim's own benchmark it adds 11 microseconds of overhead per request at 5,000 requests per second.
Best for: teams that self-host and care most about throughput and latency.
Pros: very low overhead, permissive license, and an enterprise tier with a 14-day trial.
Cons: the performance figures come from the vendor's own benchmark, and you operate it yourself.
Pricing: free to self-host. Enterprise tier priced separately.
8. Eden AI
Eden AI gives one API for LLMs and for specialised AI services such as vision, speech and OCR. It positions itself around sovereignty, with control over which providers and regions handle your requests.
Best for: teams that need LLMs and other AI APIs in one account, with EU routing.
Pros: broader than LLMs alone, and bring-your-own-key is supported.
Cons: a 5.5% platform fee, the same level as OpenRouter's Standard plan.
Pricing: provider price plus a 5.5% fee applied when you buy credits. No subscription.
9. LLM Gateway
LLM Gateway is an open-source gateway under the AGPLv3 license, with an OpenAI-compatible API across 40+ providers. You can self-host it from a single Docker image or use the hosted version.
Best for: teams that like OpenRouter's hosted model but want the option to move in-house later.
Pros: no fee with your own keys, and a clear path to self-hosting.
Cons: AGPLv3 requires you to share the source of a modified version if you offer it over a network.
Pricing: hosted at provider price plus 5% on credits, 0% with your own keys, or free to self-host.
10. TrueFoundry
TrueFoundry is an enterprise AI gateway for LLMs, MCP servers and agents. It runs in your VPC, on-premise or air-gapped, and covers SOC 2, HIPAA and GDPR requirements with RBAC and audit logs.
Best for: regulated enterprises where data cannot leave their own infrastructure.
Pros: deployment options that most gateways do not offer, with strong compliance coverage.
Cons: built for enterprise scale, which is more than a small team usually needs.
Pricing: free tier to start, with enterprise plans on request.
How do you choose?

- You already use Cloudflare and want caching: Cloudflare AI Gateway.
- EU data residency in a managed router: Requesty or Eden AI.
- Regulated enterprise: TrueFoundry or Prisma AIRS.
- OpenRouter's hosted model with an open-source exit: LLM Gateway.
How do you migrate from OpenRouter to Sidrune AI?
An app that uses the OpenAI SDK needs three changes: the base URL, the API key and the model name. Create a key in an OpenAI-format group in the Sidrune AI console, then copy the model's exact call name from Model Plaza.
python
from openai import OpenAI
client = OpenAI(
base_url="https://global.sidrune.ai/v1", # was https://openrouter.ai/api/v1
api_key="YOUR_SIDRUNE_API_KEY", # key from an OpenAI-format group
)
response = client.chat.completions.create(
model="MODEL_CALL_NAME", # copy the exact call name from Model Plaza
messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)OpenRouter prefixes each model ID with its provider, as in openai/gpt-6-luna, while Sidrune AI uses the call name shown in Model Plaza, so update the model name for every model you move. Claude Code and other Anthropic-format clients use a key from an Anthropic-format group, with the base URL set to https://global.sidrune.ai.
