## Flatkey

Flatkey positions itself as a drop-in replacement for the base URL you already use. Because the endpoint is OpenAI-compatible, an existing SDK or code path usually keeps working after you swap the URL and paste a Flatkey key. Model selection happens per request through the model ID, which means switching between labs does not require a new account, new keys, or new integration code.

Beyond raw chat completions, Flatkey aggregates utility and creation tools behind the same auth layer. Governance features are aimed at teams running agents in production: hierarchical sub-keys carry their own budgets, model allowlists, and tool permissions, and a ledger API records usage per request so spend can be attributed to a specific agent or project. A published service level agreement, channel-class failover, and the promise that Flatkey-side errors are not billed are the commercial core of the pitch.

The site advertises discounts on featured models against official list pricing, hourly verification that requests reach genuine lab endpoints, GDPR-related commitments, and zero retention of request payloads. Pricing is not published as fixed tiers, so prospective customers are expected to sign up free or contact sales for volume terms.

**Pricing & Plans:** Paid gateway with prepaid balance billing; the site pushes a free trial and directs larger buyers to sales. No fixed public plan tiers are shown on the homepage, and model prices are listed per million tokens against official list rates.

- **One OpenAI-compatible endpoint:** Point your existing SDK at Flatkey's router URL and select models by ID instead of managing a credential per provider.
- **Unified model and tool routing:** Frontier chat models and 1,000+ pay-per-call tools share one auth layer, one balance, and one invoice.
- **Sub-keys with budgets and allowlists:** Issue scoped keys per agent or environment, capped by spend and restricted to approved models and tools.
- **Automatic failover and a published SLA:** Requests route across five channel classes; when one degrades the router reroutes, backed by a 99.5% SLA document.
- **Per-request ledger and zero-charge failures:** Every call gets a request ID and usage record, and errors caused on Flatkey's side are billed at $0.

**Strengths:** OpenAI-compatible interface means minimal migration effort; Single balance and invoice across models and utility tools; Budgeted sub-keys and allowlists suit multi-agent production setups; Failed calls on the provider side are not charged, per the stated SLA

**Limitations:** No fixed public pricing tiers, so budgeting requires a sales conversation; Routing layer adds a dependency between your app and the model labs; Value depends on the discount and reliability claims holding up in practice

## Funnyskill API

Funnyskill API is an API relay, or "中转站", built for teams and individual developers in China and elsewhere who want to reach many large language models without managing separate accounts and keys for each vendor. The core promise is simplicity: a single API key, requested through an interface that follows the OpenAI format, fronts a roster of conversational, vision, image and video models. Because the request format mirrors OpenAI's, existing SDKs and client libraries can usually be repointed to Funnyskill by changing the base URL and key.

The platform positions itself around metered, usage-based billing. According to its public pricing page, chat, image-understanding, image-generation and video models are all charged by real consumption, with input and output tokens counted separately, and credits deducted as you use them after a top-up. This pay-as-you-go model suits projects with unpredictable or spiky demand, since there is no need to commit to a fixed plan upfront.

Funnyskill is one of many relay services in the Chinese AI developer ecosystem, and its value lies in convenience and breadth rather than in being a model creator itself. Buyers should treat it as a third-party intermediary: it routes requests to upstream providers, so availability, rate limits and final model behaviour depend on those upstream sources. Check the live site for the current model list, per-token prices and any promotional credit offers before committing spend.

**Pricing & Plans:** Paid, usage-based. Funnyskill charges by actual consumption with input and output tokens priced separately; users top up a balance and credits are deducted as requests are made. No specific per-token figures are quoted here — check the live pricing page for current rates.

- **Single key, many models:** Access DeepSeek, Qwen, Doubao, Kimi, GPT, Gemini and Claude Code through one API key instead of juggling vendor accounts.
- **OpenAI-compatible interface:** Requests follow the OpenAI format, so most existing SDKs and tools can be pointed at Funnyskill by swapping the base URL and key.
- **Usage-based billing:** Input and output tokens are metered separately and deducted from a topped-up balance, so you pay for what you actually consume.
- **Chat, vision, image and video models:** The catalogue spans conversational text, image understanding, image generation and video generation models.
- **Built for concurrent workloads:** Positioned to handle high-concurrency API traffic for production applications and agents.

**Strengths:** One API key and one interface for a wide range of Chinese and international models; OpenAI-compatible format reduces migration effort for existing integrations; Pay-as-you-go billing suits unpredictable or spiky usage; Covers text, vision, image and video model types

**Limitations:** It is a third-party relay, so uptime and limits depend on upstream providers; Pricing and model lists can change; you must verify current rates on the site; No fixed guarantees of SLA or enterprise support are published on the public pages; Interface and documentation are primarily in Chinese
