Newton’sNo Mid-Session Throttling
When autonomous agents run multiple tool cycles, per-minute token bursts trigger upstream OpenAI 429 rate limits. Newton’s pools capacity across verified enterprise tier routes to eliminate stalled builds.
TERMINAL CODING AGENT GUIDE
Run Codex CLI & Coding Agents with
Newton’s Developer Gateway.
Codex powers autonomous pair programming and multi-file code editing, but heavy terminal tasks quickly exhaust per-minute token limits. Route Codex through Newton’s for resilient multi-supplier capacity, instant 429 failover, and predictable prepaid billing.
Built for Autonomous Coding Sessions
Why repository-scale coding workflows run faster and more reliably through Newton’s.
Zero SDK Modifications
Newton’s exposes native /v1/chat/completions and Responses API surfaces. Point your ~/.codex/config.toml or OPENAI_BASE_URL to Newton’s without editing a line of project code.
Prepaid Safety & Exact Accounting
Run terminal agents with peace of mind. Every request draws from a prepaid balance that stops instantly at zero—protecting you from surprise runaway loop bills.
3-Step Setup: Connect Codex to Newton's
OpenAI Codex natively supports custom model providers in ~/.codex/config.toml. Follow these quick steps:
1. Export your API Key in your shell
# Add to ~/.zshrc or ~/.bashrc export NEWTONS_API_KEY="newt_your_api_key_here"
2. Add the Newton's provider profile to ~/.codex/config.toml
model = "gpt-5.3-codex" model_provider = "newtons" [model_providers.newtons] name = "Newton’s" base_url = "https://newtons.dev/api/v1" env_key = "NEWTONS_API_KEY"
3. Launch Codex with the custom provider
codex --profile newtons

How Newton’s handles high-concurrency and deep-context terminal tasks.
Strict TPM & RPM Ceilings
Direct accounts require large prepayment hurdles to escape restrictive 30k–80k TPM limits, causing frequent terminal backoff hangs on multi-file agents.
Pooled Multi-Supplier Redundancy
Requests are distributed through high-throughput enterprise supplier pipes with sub-second failover on upstream congestion or maintenance.
Real-Time Activity Telemetry
Every token and cent is visible in your console Activity dashboard in real time with prompt token, completion token, and latency breakdown.
Frequently Asked Questions
Can I use non-OpenAI models inside Codex?
Newton’s maps standard OpenAI API calls to any available coding model in our catalog, including Claude 3.7 Sonnet, DeepSeek V3/R1, and GPT-5 series models.
Does Newton’s support streaming responses in the terminal?
Yes. Server-Sent Events (SSE) streaming is natively supported at the edge, delivering instant first-token time to your terminal.
How does prepaid billing work for terminal agents?
Top up starting at just $5. You only pay for the exact tokens consumed by your coding sessions, with zero monthly recurring fees or idle seat commitments.
