Instead of managing billing with each provider separately, you register an API2D account, top it up, copy the issued key and paste it into any client that supports a custom API base URL. Because the interface mirrors OpenAI's own specification, most existing tools, SDKs and self-hosted chat UIs work without code changes. The platform bills in points (P) rather than a fixed monthly subscription, so cost tracks actual token consumption. According to API2D's own documentation, overall pricing is kept at roughly 1.5x the underlying provider's official rate, with a minimum per-request charge and free cached responses. Streamed GPT-4 replies are billed differently because they hold a connection open, and media-heavy endpoints add a modest bandwidth fee. Beyond pure relay, API2D layers on value that a raw endpoint does not offer: response caching, retrieval-augmented search, drawing tools and an agent/reseller program that lets larger accounts create and price their own sub-keys. It is aimed at Chinese-speaking developers and enthusiasts who want frictionless, domestically payable access to frontier models. For anyone evaluating it, remember that API2D is an independent third party and not affiliated with OpenAI, Anthropic or the other model vendors. **Pricing & Plans:** Pay-as-you-go in points (P); overall cost roughly 1.5x official provider pricing, with free cache hits and a minimum per-call charge. Recharge via WeChat, Alipay, Chinese bank cards or Stripe. Points expire 180 days after your last top-up. - **OpenAI-compatible endpoint:** One base URL and key work with virtually any app, SDK or self-hosted chat client that supports a custom API address. - **Multi-provider model access:** Route requests to OpenAI models, Claude, Stability diffusion, Azure TTS and vector database services from a single account. - **Points-based billing:** Consumption is metered in points with a published multiplier, so you pay for what you use rather than a flat subscription. - **Free response caching:** Identical request bodies return cached answers for free for 24 hours, and a header can disable caching when freshness matters. - **Reseller and grouping tools:** Larger accounts can batch-create keys, set default models and resell access through their own pricing pages. **Strengths:** Works with the large ecosystem of OpenAI-compatible tools out of the box; Point-based billing means low commitment and granular cost control; Response caching can make repeated queries effectively free; Built-in enhancements (search, knowledge base, drawing) go beyond a plain relay **Limitations:** Cost runs above direct provider pricing once the multiplier applies; Points expire 180 days after the last top-up, so balances need periodic renewal; No monthly plan — heavy users must estimate spend from token usage; Pricing calculation is complex because of minimum charges and bandwidth fees [Profile (Markdown)](https://openaitools.app/tool/api2d-com.md) ## Fish Audio Fish Audio, originally known as Fish Speech, is a voice-AI platform for turning text into natural speech. It combines text-to-speech, voice cloning and speech-to-text with emotional control, so you can tag a line as [whispering], [excited] or [sobbing] and get delivery that matches the script rather than flat narration. The voice library is enormous, with community-uploaded voices numbering in the millions across a wide range of languages. Cloning is fast and forgiving: a short sample is enough to build a usable voice model, and it can then speak in many languages while keeping the original timbre. Fish Audio publishes powerful APIs for real-time streaming, cloning and transcription, and positions itself for enterprise work such as conversational agents, dubbing and audiobook production. The company also keeps an open-source arm, releasing the Fish Speech model line for self-hosting, while the hosted platform adds a browser studio, avatar and image/video model integrations, and paid tiers for higher volume. Free starting tiers make it easy to evaluate before committing. **Pricing & Plans:** Freemium: free sign-up with monthly generations, plus paid subscriptions for higher volume, commercial use and API access; enterprise pricing on request. - **Expressive Text to Speech:** Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing]. - **Instant Voice Cloning:** Create a usable voice clone from a short audio sample and reuse it across scripts and languages. - **Huge Voice Library:** Browse and use a large catalog of community voices covering many languages and character styles. - **Speech to Text:** Transcribe audio with multilingual support and emotion or speaker cues for downstream editing. - **Real-time Voice APIs:** Low-latency streaming endpoints let developers build conversational agents, dubbing pipelines and audio apps. **Strengths:** Natural, emotionally controllable output that handles nuance well; Voice cloning works from a very short sample; Very large shared voice library plus open-source model lineage; Robust APIs for real-time streaming and developer integration **Limitations:** Free tier is limited and top-quality usage pushes you toward paid plans; Voice cloning raises consent and impersonation risks that teams must manage; Some features and model names change quickly, so docs can lag the product [Profile (Markdown)](https://openaitools.app/tool/fish-speech.md) ## Frequently Asked Questions ### How do API2D and Fish Audio compare in monthly traffic?
