Newton’sSub-Second TTFT
Zero middleware queueing or cold-start hops. Requests route over Cloudflare global edge directly to verified tier-1 inference endpoints.
GATEWAY BENCHMARK & COMPARISON
An OpenRouter alternative built for
latency & prompt caching.
When coding agents send 50,000+ tokens of codebase context on every turn, middleware delays and cache misses get expensive. Newton’s delivers direct-to-metal edge routing, true prompt cache pass-through, multi-supplier failover, and verifiable cryptographic receipts.
Engineered for Coding Agents & Heavy Context
Four architectural advantages for Cursor, Claude Code, Cline, and production agent swarms:
Full Cache Pass-Through
Preserve prompt caching discounts across Anthropic and OpenAI architectures. Save up to 85% on context-heavy IDE turns.
Zero-429 Failover
When an upstream provider hits sudden capacity throttles, multi-supplier fallback routes your request seamlessly without breaking your IDE session.
Cryptographic Receipts
Every request returns an itemized cryptographic cost receipt and resolved model ID, ensuring total transparency on every micro-cent.
Newton’s vs OpenRouter: Direct Comparison
Architectural breakdown for engineering teams and agent developers.
| Dimension | OpenRouter | Newton’s Developer Gateway |
|---|---|---|
| Routing Architecture | Centralized intermediary proxy | Global edge routing (Cloudflare Workers) |
| Prompt Cache Discount | Variable / dependent on endpoint | Direct cache pass-through (up to 85% discount) |
| Rate Limit (429) Handling | Pass-through error to client | Multi-supplier fallback & automated retry routing |
| Model Support | Broad catalog with unverified community endpoints | Curated frontier models (Claude Sonnet 5, GPT-5.6 Sol, DeepSeek Reasoner, Gemini 3.8 Flash) |
| Cost Transparency | Basic dashboard logs | Immutable itemized ledger with token breakdowns |
| Prepaid Minimum | Prepaid balance with payment gateway processing fees | Instant start from $1 trial up to enterprise topups |
| Agent & MCP Compatibility | OpenAI API shape | OpenAI & Anthropic drop-in compatibility + MCP ready |
Switch from OpenRouter in 30 Seconds
Update your base URL and API key in any OpenAI SDK or IDE configuration.
# In Cursor / Cline / Windsurf / Aider:
export OPENAI_BASE_URL="https://newtons.dev/api/v1"
export OPENAI_API_KEY="newt_your_api_key"
# In Python:
from openai import OpenAI
client = OpenAI(
base_url="https://newtons.dev/api/v1",
api_key="newt_your_api_key"
)
response = client.chat.completions.create(

Frequently Asked Questions
Common questions from developers migrating from OpenRouter.
Why do developers switch from OpenRouter to Newton’s?
Newton’s provides sub-second first-token routing with zero aggregator queue delay, automatic prompt-cache savings on heavy coding sessions (Cursor, Claude Code, Windsurf), and deterministic prepaid accounting without hidden middleman fees.
Is Newton’s cheaper than OpenRouter?
Yes, especially for coding agents and long-context workflows. Newton’s passes through provider prompt-caching discounts directly (saving up to 85% on Anthropic and OpenAI cached context) and does not take unpredictable deposit cuts or hidden spread fees.
How does Newton’s prevent LLM rate limit (429) errors?
Unlike aggregators that pass 429 errors straight through to your IDE or app, Newton’s maintains multi-supplier routing with automated instant failover. If an upstream supplier is throttled or degraded, your request automatically falls back to an alternate verified route.
Is Newton’s a drop-in replacement for OpenRouter?
Yes. Newton’s uses the exact same OpenAI-compatible REST shape (POST /v1/chat/completions) and standard Bearer token authorization. You only need to switch your base URL to https://newtons.dev/api/v1 and provide your Newton’s API key.
Does Newton’s support Claude Sonnet 5, GPT-5.6 Sol, and DeepSeek Reasoner?
Yes. All frontier reasoning, coding, and vision models (including Claude Sonnet 5, DeepSeek Reasoner, GPT-5.6 Sol, and Gemini 3.8 Flash) are available through a single unified API key and shared prepaid balance.
Can I use Newton’s with MCP (Model Context Protocol) and agent tools?
Yes. Newton’s natively supports OpenAI function calling and Anthropic tool use schemas, making it an ideal MCP gateway for autonomous agents and IDE workflows.
