API basics
API basics
OpenAI-compatible API
An OpenAI-compatible API is a provider endpoint that accepts familiar OpenAI-style request shapes, usually under a /v1 base URL with Bearer authentication. It is not automatically an official OpenAI service. With unlimitedcodex, buyers use the delivered base URL, API key, setup files, and model IDs after manual setup.
API basics
OpenAI-compatible base URL
An OpenAI-compatible base URL is the API origin a client sends requests to when using an OpenAI-style provider. It often ends at or routes to /v1. In unlimitedcodex, the base URL is delivered manually after checkout and should be tested with /v1/models before long workflows.
API basics
API key scope
An API key scope is a permission boundary that limits what a key can do, such as chat writes, embeddings writes, image requests, or usage reads. Scopes reduce blast radius, but full keys still belong in server-side secret storage, not public tools, frontend code, screenshots, or support messages.

Codex API access
Codex API access means using delivered API credentials and model details for coding-agent workflows such as Codex CLI, Codex IDE, SDK tests, refactors, and automated build tasks. In unlimitedcodex, GPT-5.5 XHigh is available at $19/week or an eligible $59 first month followed by $69/month, while GPT-5.6 Sol is available at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month; all use manual setup and a 4 concurrent connections boundary.

GPT-5.6 Sol API access
GPT-5.6 Sol API access is unlimitedcodex's separate premium OpenAI-compatible package family. For an eligible account's first paid order, Sol Weekly is $69 then $89/week and Sol Monthly is $179 then $199/month; both are delivered manually after checkout and include unlimited token consumption with 4 concurrent connections. One welcome price is available per account. They are distinct from the GPT-5.5 XHigh packages.
unlimitedcodex package
Unlimited token consumption
Unlimited token consumption means unlimitedcodex does not position the public package around per-token metering anxiety, but every unlimited claim must include the operating boundary: 4 concurrent connections per account. It is not unlimited parallel traffic, an enterprise SLA, or official OpenAI capacity.
unlimitedcodex package
4 concurrent connections
4 concurrent connections means an unlimitedcodex account is publicly positioned for up to four active API calls at the same time. It is the operating boundary that must accompany unlimited token consumption claims. Teams should queue additional workers or choose other infrastructure for higher concurrency.
setup checks
setup checks
Manual API setup delivery
Manual API setup delivery means a real operator provisions and sends access details after checkout instead of issuing an instant self-serve key. For unlimitedcodex, expected delivery is usually 10 minutes to 5 hours and includes API key, base URL, setup files, activation date, start date, and end date.
setup checks
Endpoint smoke test
An endpoint smoke test is a tiny, low-risk request used to prove that the base URL, API key, model ID, endpoint shape, and response format work before a long run. For OpenAI-compatible APIs, start with /v1/models and one small chat/completions request, then test embeddings or images if needed.
setup checks
Model-list check
A model-list check is a GET /v1/models request that confirms which model IDs the delivered endpoint exposes. It prevents buyers from guessing model names before delivery and helps catch wrong base URLs, wrong keys, or unsupported model values before long runs.
setup checks
OpenAI SDK migration
OpenAI SDK migration means moving an app from the default OpenAI endpoint to another OpenAI-compatible provider by changing configuration such as base URL, API key, and model ID while keeping the request shape similar where supported. For unlimitedcodex, use delivered setup values and verify /v1/models before long runs.
buyer comparison
buyer comparison
API access package
An API access package is a paid access window or subscription that gives a buyer provider details such as an API key, base URL, model IDs, setup files, and package dates. unlimitedcodex packages GPT-5.5 XHigh at $19/week or an eligible $59 first month followed by $69/month and GPT-5.6 Sol at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month, with manual delivery and unlimited token consumption with 4 concurrent connections.
buyer comparison
Per-token billing
Per-token billing charges API usage based on the number of input and output tokens processed. It can be efficient for low-volume, predictable workloads, but coding-agent retries and long context can make spend hard to forecast. unlimitedcodex instead sells weekly or monthly access windows with 4 concurrent connections.
buyer comparison
AI gateway
An AI gateway is an infrastructure layer between an application and one or more model providers. It can centralize provider credentials, routing, rate limits, retries, caching, observability, budgets, and policy enforcement. A gateway does not automatically include model access; teams usually connect provider accounts or a separate access source.
buyer comparison
Model router
A model router chooses which model or provider handles a request based on rules such as cost, latency, fallback, quality, or policy. unlimitedcodex is not a broad router: it sells GPT-5.5 XHigh access at $19/week or an eligible $59 first month followed by $69/month and premium GPT-5.6 Sol access at an eligible $69 first week followed by $89/week, or a $179 first month followed by $199/month through a delivered OpenAI-compatible setup.
