💰 2026年最佳 API 成本优化

Machine-readable web-search API that AI agents can pay for per call using USDC via x402 protocol and MCP integration.

Unified AI API for video, music, image, and LLM generation — one API key for Kling, Suno, Flux, Claude, Gemini, DeepSeek and more.

Bifrost is a high-performance, open-source AI gateway that unifies 23+ model providers (OpenAI, Anthropic, AWS Bedrock, Google Vertex, and more) behind a single OpenAI-compatible API. It adds automatic failover, adaptive load balancing, semantic caching, guardrails, and MCP support with sub-100µs overhead at 5k RPS — marketed as up to 50× faster than LiteLLM.

Save tokens by loading only relevant tools - watches repo and task, walks a graph of 91k+ skills, 467 agents, 10.7k MCP servers to recommend a small bundle.

Multi-agent AI runtime with OS-inspired primitives — job scheduling, DAG orchestration, memory, tool execution and real-time observability, built with FastAPI, Celery, PostgreSQL and LiteLLM.

A distributed storage engine for GPU workloads, written in Rust on io_uring. OpenLake offloads LLM KV cache to host RAM and disk across your GPU fleet so prefill work is reused instead of recomputed, cutting inference cost and time to first token.

Open-source LLM gateway that unifies 100+ providers with automatic fallback and cost tracking.

An MCP server that lets AI assistants save and share answers across sessions so your research persists.

A self-hosted governing gateway that sits between your app and any LLM provider to reform prompts, cap max_tokens, enforce per-caller budgets, and cache deterministic calls.

Cut LLM API costs without breaking responses by optimizing prompt token usage.

An API service for voice emotion detection with real-time short-audio and async long-audio modes, plus Python/JavaScript SDKs.
