LLM Gateway for Coding Agents

One OpenAI-compatible API for coding agents, one balance, one usage trail — and the models your tools already expect.

01

Setup

An LLM gateway for coding agents means the first setup step is changing the base URL and using the same bearer token everywhere. The protocol can stay OpenAI-compatible, Anthropic-native, or Gemini-native depending on the tool.

Read details

An LLM gateway for coding agents keeps the integration surface small when your stack changes from an IDE extension to a CLI agent, from a local script to a hosted automation, or from a quick prototype to a team workflow. Instead of creating separate keys for OpenAI, Claude, Gemini, and every SDK wrapper, you point the client at OmniaKey and keep the same auth pattern. The model id still decides which provider answers, but the operational surface stays under one account. That is the practical difference between a generic LLM proxy and an LLM gateway for coding agents: the gateway is built around real developer tools, base URL changes, bearer tokens, usage review, and predictable model routing.

02

Control

An OpenAI-compatible API for coding agents gives teams a single place to watch quota, usage, spend, and model mix. That matters when agents run repeatedly and small prompts turn into long editing sessions.

Read details

An LLM gateway for coding agents also makes cost review easier. Agentic coding sessions can burn tokens through planning, tool calls, edits, retries, code search, and long context windows. When usage is split across three provider dashboards, the real cost of a coding workflow is hard to see. OmniaKey keeps call metadata, token counts, model mix, latency, and spend in one dashboard, so developers can compare Claude, GPT, and Gemini without rebuilding reporting around each provider. The same OpenAI-compatible API for coding agents works across small experiments and longer team sessions, which keeps billing, refunds, quota, and spend alerts in one place.

03

Choice

An LLM gateway for coding agents keeps Claude, GPT, and Gemini available without forcing developers to pick a permanent winner. Select the model per task and keep the surrounding workflow stable.

Read details

An LLM gateway for coding agents does not mean one model for every task. The point is controlled choice. Use Claude when the repo context is complex, GPT when you want strong general reasoning or OpenAI-compatible tooling, and Gemini when long-context work fits the job. OmniaKey routes the request to the model you named. It does not silently swap providers to hide outages or chase margin, because coding agents need predictable behavior more than clever fallback magic. A Claude Code API gateway, a Cursor OpenAI-compatible API, a Cline OpenAI-compatible API, and an OpenCode API gateway all need the same basic promise: the model you configured is the model that runs.

04

Billing

A coding-agent gateway keeps top-ups, token spend, and refunds in one account. It is easier to audit than separate cards, separate invoices, and separate provider dashboards.

Read details

An LLM gateway for coding agents is especially useful when a team standardizes a base URL across Claude Code, Codex-style tools, Cursor, Cline, OpenCode, aider, Continue, Zed, shell scripts, and CI jobs. New developers get one setup path. Finance gets one billing trail. Engineering gets model choice without handing every teammate a pile of provider credentials. You can still keep provider-specific habits, but the day-to-day coding surface becomes much simpler. OmniaKey works as an OpenAI-compatible API for coding agents while also keeping Anthropic-native and Gemini-native routes available for tools that prefer those protocols.

05

Migration

An LLM gateway for coding agents lets teams add or replace tools without reissuing provider credentials. The base URL can stay stable while the model mix changes.

Read details

An LLM gateway for coding agents also keeps migration reversible. A developer can start with one tool, add another agent later, and keep the same account, balance, and observability. If a model becomes too expensive for a task, switch the model id. If a workflow needs Anthropic-native messages or Gemini-native content generation, use that protocol without rebuilding the surrounding billing and access control. The key point is not hiding providers; it is making provider choice easier to operate. OmniaKey gives teams one OpenAI-compatible API for coding agents, one Claude Code API gateway path, one OpenCode API gateway path, and one usage record for everyday development.

Questions

About billing, models, and integration

Why up to 93% cheaper than the official price?
Launch-period promo with provider-specific discounts: save 93% on GPT, 80% on Claude, and 20% on Gemini. No tier games, no minimum spend, no annual contract.
What about after the launch promo?
Launch-period promo — and yes, that means it's not forever. We'll email you ahead of any change and keep this page in sync.
Is the model the same model?
Yes. The provider, model, and weights you ask for are what runs. No quantization, no distillation, no substitution. The bill changes; the model doesn't.
What if an upstream provider goes down?
We connect directly to Anthropic, OpenAI, and Google. If a provider is down, that provider stays down on our end too — we don't silently route to a different model to mask outages, since that would tear up the same-model promise above. The dashboard shows live status per provider; switch to whichever's still working. Our dual-region setup covers our own infrastructure failures, not theirs.
Does OmniaKey work as a Claude Code, Cursor, Cline, and OpenCode API gateway?
Yes. OmniaKey works as a Claude Code API gateway, a Cursor OpenAI-compatible API, a Cline OpenAI-compatible API, and an OpenCode API gateway. There's a copy-paste env block earlier on this page; the base URL suffix differs by provider (OpenAI /v1, Gemini /v1beta, Anthropic uses the bare URL) and the block highlights the difference. Aider, Continue, and anything OpenAI/Anthropic/Gemini-compatible work the same way.
What about latency? Are you adding a hop?
Yes, there's one routing hop. Same-region deployment puts it around 30-90ms — relative to TTFT of 200ms+ and a multi-second full response, you won't notice it.
Do you log my prompts?
No prompt or response bodies stored by default. We only keep metadata for billing and the usage dashboard — timestamps, token counts, model, latency. Email us if you need debugging logs.
Where are you based, and who's behind this?
A small team of developers who got tired of juggling three dashboards and writing the same retry loop. Infrastructure is hosted across US-East and AP-Tokyo for redundancy. Reach us at [email protected] — replies come from real humans.
How do I pay?
Credit and debit cards (handled by Stripe) and crypto (USDT). Top up any amount, spend it down, no expiry. Refunds available on unused balance within 30 days.
