Fairy Codes is a high-performance AI gateway that routes a single OpenAI-compatible API to OpenAI, Anthropic, Google, Mistral and 200+ models — with smart failover, load balancing, and real-time cost analytics built in.
# Point the OpenAI SDK at Fairy Codes — that's it.
from openai import OpenAI
client = OpenAI(
base_url="https://api.fairy.codes/v1",
api_key="fc-live-xxxxxxxxxxxx",
)
resp = client.chat.completions.create(
model="claude-opus-4-8", # or gpt, gemini…
messages=[{"role": "user",
"content": "Hello, Fairy!"}],

Stop wiring up half a dozen SDKs, rate limiters, and billing dashboards. Fairy Codes gives you one resilient control plane for every provider.
One OpenAI-compatible endpoint speaks to every provider. Switch models by changing a single string — no rewrites, no new SDKs.
Automatically fail over to a backup provider on errors, rate limits, or latency spikes. Your users never see a 429.
Track spend per key, model, and team to the token. Set hard budgets and get alerted before you blow past them.
Issue scoped virtual keys with per-key rate limits, model allow-lists, and spend caps. Rotate or revoke in one click.
Cut latency and cost by serving repeat and near-duplicate prompts from an intelligent cache you fully control.
Requests are served from the nearest region with sub-30ms overhead, so the gateway is never the bottleneck.
Configure a priority chain of models once. Fairy Codes continuously health-checks every upstream and reroutes traffic in milliseconds — keeping your product online when any single provider isn't.
Distribute traffic across providers and regions by real-time performance.
Transparent retries with exponential backoff across your model chain.
Full support for streaming, function calling, and multimodal inputs.
Most teams migrate in an afternoon. If you already use the OpenAI SDK, you're 90% done.
Sign up and generate a Fairy Codes virtual key. Bring your own provider keys, or use ours and pay as you go.
Point any OpenAI-compatible client at api.fairy.codes. No new dependencies to install.
Route to any model by name and watch latency, spend, and errors stream into your dashboard in real time.
Start free. Pay only for what you route. No seat fees, no lock-in.
For side projects and getting a feel for the platform.
For production apps that need resilience and insight.
For teams with scale, compliance, and SLA needs.
Yes. Keep your existing OpenAI SDK and code — just change the base URL and API key. Every request, including streaming, function calling, and vision, follows the standard chat completions schema, so you route to Anthropic, Google, or any provider without rewrites.
Absolutely. Use a bring-your-own-key setup and Fairy Codes simply orchestrates routing, failover, and analytics on top of your own provider accounts. Or use our managed credits and pay a single, consolidated bill — the choice is yours per workspace.
You define a priority chain of models. The gateway health-checks every upstream and, on any error, rate limit, or latency spike, transparently retries against the next model in your chain — often before the client even notices a delay.
By default we log only metadata needed for analytics and billing — never your prompt or response bodies. Request/response logging is fully opt-in and configurable per key, and Enterprise plans include zero-retention routing and SOC 2 controls.
Typically under 30ms. Requests are served from the nearest edge region and proxied straight through with streaming intact, so the overhead is negligible next to model inference time — and caching often makes responses faster overall.
Join thousands of teams routing every model through one resilient gateway. Free to start — no credit card required.
