## APIMaster

APIMaster is an API routing marketplace for teams that want access to frontier models without paying frontier list prices. It aggregates verified provider channels for GPT, Claude, Gemini, DeepSeek, Qwen, Kling, Seedance and others behind one OpenAI-compatible endpoint, then routes each request to the lowest-cost verified channel available. You top up a single prepaid balance and burn it across every model in the catalogue.

The core trust problem with cheap API resale is model substitution. APIMaster addresses it with an LLM fingerprint test applied to each provider before it is listed, so the model answering your request matches the one on the pricing page. The site also exposes uptime figures and per-million-token input and output rates for each route, which makes it possible to see that a cheaper channel is genuinely live rather than simply cheaper.

Reliability is handled with automatic failover. If a channel degrades, traffic moves to the next verified provider without you rotating keys or redeploying. The catalogue covers LLM, image, video, audio and embedding endpoints, and because the interface is OpenAI-compatible, existing agent tooling and IDE integrations such as Cursor, Claude Code, LangChain and LiteLLM work with only a base URL and key swap. It is aimed at indie builders and product teams whose main cost driver is inference spend.

**Pricing & Plans:** Pay-as-you-go against a prepaid balance. Rates are quoted per million input and output tokens and vary by model and routed provider, with discounts advertised at up to around 90% off official list pricing. Top-ups are made via USDT or Epay; no credit card is required to create a key.

- **Broad model catalogue:** The catalogue spans over 90 models across LLMs, image, video, audio and embedding endpoints, individually priced per million tokens.
- **Fingerprint-verified APIs:** Each listed provider passes an LLM fingerprint test intended to confirm you receive the exact model you paid for, with no silent substitution.
- **Automatic failover routing:** If a routed channel goes down, requests are automatically routed to the next verified provider, so production calls keep running without manual key rotation.
- **One OpenAI-compatible key:** Use one key and one prepaid balance across every model, with an OpenAI-compatible base URL for tools like Cursor, LangChain and LiteLLM.
- **Cost and uptime transparency:** The site exposes per-provider uptime figures and input and output token rates so you can compare routes before committing traffic.

**Strengths:** Large single-point catalogue of models behind one OpenAI-compatible key; Discounts advertised at up to 90% off official list pricing; Automatic failover removes single-upstream downtime as a failure mode; Per-provider uptime and token rates are published for comparison

## Milk Infrastructure

Milk Infrastructure starts from a simple observation: every model call your application makes produces a request and a response, and most of that traffic is thrown away. Milk tries to give those calls a second act. Instead of replacing your stack, it inserts itself as a drop-in OpenAI-compatible gateway — you keep the official SDK and your existing code, and change only the base URL and API key.

The system is split into two pieces. Milk Parlor is the gateway: it forwards your calls, returns the answers, and quietly persists eligible request–response pairs to object storage. Milk Man is the agent that works on what comes after. Hand it a goal and it runs commands, spins up cloud models, measures outcomes, and records what it learned, whether that means summarizing accumulated traffic, generating fresh training tasks, or fine-tuning and comparing an open model against a baseline.

Pricing is paid and the project is built around open-source code, with separate repositories for Parlor and Milk Man. The site is refreshingly honest about scope: it states plainly that Milk does not guarantee a better model, that failures are kept alongside successes, and that speed and answer quality are distinct metrics judged against your own chosen baseline rather than a universal leaderboard.

**Pricing & Plans:** Paid product with open-source gateway and agent code. No public price tiers are listed; language model, storage and compute costs are driven by your own choices — local files or S3-compatible storage, managed inference APIs, or self-owned Baseten/Modal GPUs. Contact the team for commercial terms.

- **Two-value gateway setup:** Point the official OpenAI SDK at Milk Parlor by changing just OPENAI_BASE_URL and OPENAI_API_KEY; Chat Completions and Responses calls stay exactly as they were.
- **Automatic traffic capture:** Parlor returns your model's answer as usual while saving eligible request–response pairs in the background, grouped as tasks under your account's unique ID.
- **Milestone summaries:** A heartbeat counts saved exchanges without making model calls, and at configurable thresholds a job summarizes topics, tasks, and response times.
- **Milk Man experiment agent:** Give it a goal and it runs commands, starts cloud models, measures results, and saves what it learns — continuing even after you close the dashboard.
- **Train, tune and compare:** A teacher model writes new tasks from your traffic, open models are trained and tuned, and answers, speed, and cost are compared on identical tasks, with an operator-signed routing rule before any traffic moves.

**Strengths:** Keeps your existing OpenAI SDK code and changes only two environment values; Saves request–response pairs automatically, without instrumenting every call yourself; Agent keeps running experiments after you close the dashboard; Gateway and agent are published as open-source code

**Limitations:** No published price list — commercial terms come from a conversation with the team; Setup still assumes familiarity with environment variables, object storage and GPU providers; It is an experiment and observability layer, not a guarantee of a better model
