## 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

## LLM API Costs Widget

LLM API Costs Widget takes one of the most tedious chores for anyone building on top of a large language model — repeatedly opening a billing dashboard to see how much you have spent — and turns it into a single glance. You place the widget on your Home Screen, and your OpenAI API costs become ambient information, the same way the weather or your battery level does. That makes it easy to notice an unusual spike before it turns into a surprise invoice, and easy to stay aware of daily burn while prototyping.

The app is deliberately small and focused. It is a utilities app that installs on iPhone, iPad and Apple Vision, requires a recent OS release (iOS 18.2 or later), ships in a few megabytes, and is offered as a one-time paid download rather than a subscription. Its App Store privacy disclosure states that the developer collects no data, which matters for a tool that touches something as sensitive as API credentials and billing information.

Because it is a third-party app rather than something published by OpenAI, its feature set depends on the API surface OpenAI exposes and on the developer's own maintenance. Treat it as a convenience layer over your billing dashboard: great for quick awareness and habit-building, not a replacement for the authoritative numbers in your account console.

**Pricing & Plans:** Paid one-time download. The App Store listing shows a single low-cost purchase price (listed as €1.99 in the Spanish storefront) with no subscription. Pricing varies by region and storefront, so check your local App Store page for the exact amount.

- **Home Screen cost widget:** Shows your OpenAI API cost information directly on the Home Screen so you do not need to open a dashboard for a quick check.
- **Glanceable spend awareness:** Keeps usage visible throughout the day, helping you spot unusually high activity before your monthly bill arrives.
- **Broad Apple device support:** Runs on iPhone, iPad and Apple Vision, with desktop compatibility on Apple silicon Macs, from a single small download.
- **One-time paid purchase:** A simple low-cost download instead of a recurring subscription, so there is no ongoing fee just to monitor your spending.
- **Privacy-conscious build:** The App Store privacy label states that the developer collects no data, which is reassuring for a tool that works with API billing information.

**Strengths:** Turns recurring dashboard checks into a passive, always-visible readout; Very small download and a focused feature set with little to configure; One-time paid model with no subscription commitment; No data collection declared in the App Store privacy label

**Limitations:** Available only on Apple platforms; there is no Android, web or desktop-native equivalent; Purpose is narrower than a full cost-analytics or observability suite; Coverage depends on what the OpenAI API exposes, so other providers may not be represented
