Step 1

Quickstart

Zyloo speaks the OpenAI API verbatim. If your code talks to api.openai.com, redirect it at our base URL and you're done.

Base URLs

Agentic CLIs — Claude Code, opencode, and the like — point at https://api.zyloo.io. OpenAI-style clients and editors such as Cursor use https://api.zyloo.io/v1.

bash

# 1. Install the official SDK (any language)
npm install openai

# 2. Get your key from https://zyloo.io/dashboard
export ZYLOO_KEY=sk-zy-...

# 3. Make your first call
curl https://api.zyloo.io/v1/chat/completions \
  -H "Authorization: Bearer $ZYLOO_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "zyloo/claude-opus-4-7",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

Using an agentic coding CLI? Set its base URL to https://api.zyloo.io and your Zyloo key, then run as usual.

bash

# Claude Code, opencode, and other agentic CLIs
export ANTHROPIC_BASE_URL=https://api.zyloo.io
export ANTHROPIC_API_KEY=$ZYLOO_KEY

# Cursor and other OpenAI-compatible editors
#   Base URL:  https://api.zyloo.io/v1
#   API key:   $ZYLOO_KEY

Integrations

The big five coding CLIs

Every popular terminal agent speaks the OpenAI or Anthropic wire format, so they all run on a Zyloo key — copy the block for your tool and swap in any model from the price index.

Claude Code · Anthropic

Anthropic's terminal agent. Point its Anthropic-format variables at the gateway.

bash

npm install -g @anthropic-ai/claude-code

export ANTHROPIC_BASE_URL=https://api.zyloo.io
export ANTHROPIC_API_KEY=$ZYLOO_KEY
export ANTHROPIC_MODEL=zyloo/claude-opus-4-7-thinking

Codex CLI · OpenAI

OpenAI's open-source CLI. Register Zyloo as a provider in config.toml.

bash

npm install -g @openai/codex
export ZYLOO_KEY=sk-zy-...

toml

# ~/.codex/config.toml
model = "zyloo/gpt-5.5"
model_provider = "zyloo"

[model_providers.zyloo]
name = "Zyloo"
base_url = "https://api.zyloo.io/v1"
env_key = "ZYLOO_KEY"
wire_api = "chat"

opencode · open source

The model-agnostic open-source favourite. Add Zyloo as a custom provider in opencode.json.

bash

npm install -g opencode-ai
export ZYLOO_KEY=sk-zy-...

json

// opencode.json
{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "zyloo": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Zyloo",
      "options": {
        "baseURL": "https://api.zyloo.io/v1",
        "apiKey": "{env:ZYLOO_KEY}"
      },
      "models": {
        "zyloo/claude-opus-4-7": {},
        "zyloo/gpt-5.5": {}
      }
    }
  }
}

Aider · open source

The git-native pair programmer. Uses the standard OpenAI-compatible variables.

bash

python -m pip install aider-install && aider-install

export OPENAI_API_BASE=https://api.zyloo.io/v1
export OPENAI_API_KEY=$ZYLOO_KEY

aider --model openai/zyloo/claude-opus-4-7

Qwen Code · Alibaba

Alibaba's coding agent. Reads OPENAI_* variables — nothing else to configure.

bash

npm install -g @qwen-code/qwen-code

export OPENAI_BASE_URL=https://api.zyloo.io/v1
export OPENAI_API_KEY=$ZYLOO_KEY
export OPENAI_MODEL=zyloo/deepseek-v4-pro

Security

Authentication

Every request must include a bearer token in the Authorization header. Keys are scoped per project and can be revoked instantly from the dashboard.

http

Authorization: Bearer sk-zy-9f3a0e5b...

For local development we recommend storing the key in a .env file and loading it through your runtime — never commit keys to source control.

Catalog

Models

Reference any model by its canonical Zyloo id. Every id is namespaced under zyloo/... so it's unambiguous across providers. The full list of 58 models lives on the Models page.

bash

# A few examples — see /dashboard/models for the full list
zyloo/claude-opus-4-7-thinking
zyloo/claude-opus-4-7
zyloo/gpt-5.5
zyloo/gemini-3.5-flash
zyloo/deepseek-v4-pro
zyloo/grok-4.3

bash

curl https://api.zyloo.io/v1/models \
  -H "Authorization: Bearer $ZYLOO_KEY"

Tip

Models with extended reasoning end in -thinking — for example zyloo/claude-opus-4-7-thinking or zyloo/gpt-5.5-xhigh.

Endpoint

Chat completions

The same JSON shape as OpenAI's /v1/chat/completions. Tools, JSON mode, vision and structured outputs are supported on every compatible model.

import OpenAI from "openai";

const zyloo = new OpenAI({
  apiKey: process.env.ZYLOO_KEY,
  baseURL: "https://api.zyloo.io/v1",
});

const res = await zyloo.chat.completions.create({
  model: "zyloo/gemini-3.5-flash",
  messages: [
    { role: "system", content: "You are concise." },
    { role: "user",   content: "Summarize this PR..." },
  ],
  temperature: 0.2,
  max_tokens: 512,
});

console.log(res.choices[0].message.content);

Endpoint

Image generation

Image models generate pictures from a text prompt at /v1/images/generations — the same request and response shape as OpenAI's Images API. Image models are billed per image, not per token, and appear on the Models page with a per-image price.

const image = await zyloo.images.generate({
  model: "zyloo/your-image-model",   // any model marked "Image" on /models
  prompt: "A watercolor lighthouse at dawn",
  n: 1,                              // 1–4 images per request
  size: "1024x1024",
});

console.log(image.data[0].url ?? image.data[0].b64_json);

bash

curl https://api.zyloo.io/v1/images/generations \
  -H "Authorization: Bearer $ZYLOO_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "zyloo/your-image-model",
    "prompt": "A watercolor lighthouse at dawn",
    "n": 1
  }'

How image billing works

Each request is charged price-per-image × number of images delivered. `n` selects how many images to generate (1–4, default 1).
You are only charged for images actually delivered: if the provider fails, times out, or returns an error, the hold is released back to your balance automatically.

Models flagged as supporting edits also accept POST /v1/images/edits with a multipart form body (source image + prompt) at the same per-image price. Models without the flag return a 400 on that endpoint.

bash

curl https://api.zyloo.io/v1/images/edits \
  -H "Authorization: Bearer $ZYLOO_KEY" \
  -F "model=zyloo/your-image-model" \
  -F "image=@photo.png" \
  -F "prompt=Add a red scarf" \
  -F "n=1"

Realtime

Streaming

Pass stream: true to receive Server-Sent Events with the same delta format as OpenAI.

const stream = await zyloo.chat.completions.create({
  model: "zyloo/claude-opus-4-7",
  stream: true,
  messages: [{ role: "user", content: "Tell me a story" }],
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta?.content ?? "");
}

Reliability

Errors

Zyloo returns OpenAI-compatible error objects. Common codes:

Code	Meaning	Action
401	Invalid key	Rotate from dashboard
402	Insufficient credit	Top up wallet
429	Rate limited	Backoff, we route to a sibling provider
5xx	Upstream failure	Auto-retry with idempotency-key
