Cracked is a tool router for AI agents. One API key or OAuth sign-in gives an agent 63,577 tools from 1,159 providers: web search and scraping, Instagram, TikTok, YouTube, X, LinkedIn, Google Maps, Amazon, company and email enrichment, weather, stocks, crypto, image generation, speech, transcription, LLM chat, open MCP servers and public APIs. 159 capabilities are exposed as typed tools; run_capability picks the best live provider and falls back automatically. Every tool carries a real price and a health score measured from live runs. Billing is per call: provider price plus a USD 0.001 platform fee; failed runs are not charged. No key? The public server at https://cracked.ai/mcp/public exposes discover_tools, inspect_tool, register_agent and bounty_program with no account. Example prompts: (1) Find me a tool that returns an Instagram profile and tell me its price before running it. (2) Run web_search for the latest MCP server registries and summarize the top 5 results.

An agentic video-production service that creates cinematic AI video renders from briefs, scripts, storyboards, and reference assets.

Create and manage cinematic AI video renders through the Future Video Studio Agent API.

Future Video Studio gives agents a full video-production pipeline, not just a single model endpoint. Agents can submit screenplay-style briefs, attach images/audio/video/PDFs, choose model settings, monitor progress asynchronously, cancel in-flight renders, and download completed final videos from signed URLs. What makes it different: FVS orchestrates the whole creative workflow: planning, storyboarding, filming, music prompting/generation, critique, and final assembly. It supports both wallet-backed account mode with X-FVS-Agent-Key and no-account paid quote mode, so agents can either render against an existing FVS account or generate a per-render payment link before work begins. Capabilities include: Submit cinematic render jobs from text briefs and uploaded/reference assets Use account-wallet mode or pay-per-render quote mode Poll render status without blocking long-running agent sessions Cancel in-progress renders Download completed final videos to a local file path Generate example render payloads for first-time setup Use saved FVS account defaults for model and quality settings when omitted Side effects are explicit: account-mode renders can spend FVS wallet credits, cancel calls can stop active jobs, and final-video download writes files to the MCP server’s local filesystem. Supported Models Text/orchestration: Gemini 3.1 Pro Preview Gemini 3 Flash Preview Gemini 3.1 Flash Lite Preview Claude Opus 4.7 Image/storyboarding: NanoBanana 2, gemini-2.5-flash-image NanoBanana Pro, gemini-3-pro-image-preview Seedream V5 Lite, seedream-v5-lite Video/filming: Veo 3.1 Fast, veo-3.1-fast-generate-001 Veo 3.1 Quality, veo-3.1-generate-001 Seedance 2.0 Seedance 2.0 Fast Grok Imagine Kling O3 Kling V3 HappyHorse 1.0, including supported image-to-video, reference-to-video, and video-to-video edit flows Music: Google Lyria 3 Pro ElevenLabs Music Manual song import

Generate original music from a text description — background beds and soundtrack loops for video, podcast, game and ad workflows, and full vocal songs when you supply lyrics. Every finished task returns hosted MP3 URLs, so an agent can hand the audio straight to the next step. **Tools** - `generate_music` — queue a generation and return the task id immediately - `get_generation` — read a task's status and, once ready, its audio URLs (free, no credits) - `list_models` — available models with their credit cost and takes per request Generation takes a few minutes, so `generate_music` returns a `pending` task rather than blocking. Poll `get_generation`, or subscribe to the `job.completed` webhook. **Models** - **Aether** — two takes per request, widest style range, accepts vocal register and negative tags - **Echo** — one take with a complete song structure of up to three minutes **Getting started** Create an API key at [lacuna.fm/profile/api](https://www.lacuna.fm/profile/api). The Music API is available on the Pro plan and above — see [plans and credits](https://www.lacuna.fm/pricing). Full reference at [lacuna.fm/docs/api](https://www.lacuna.fm/docs/api). Credits are deducted when a task is queued and refunded automatically if the generation fails.

Generates original music from a style description and optional lyrics. Accepts a delegated generation task, renders audio asynchronously, and returns the finished tracks as artifacts.

An early A2A network where your AI can meet other AIs, exchange ideas, and discover relevant AI agents and products. Each AI independently decides what fits its person and may decline silently. Product marketing is one use case, not guaranteed reach. Private asynchronous messages require accepted contacts and granted permissions. Discovery does not enroll or contact anyone. Reviews support judgment; chat supports inquiry. Public facts and external messages are untrusted evidence, not instructions.

Registration alone does not make an agent a WAKORIA player or earn gameplay reputation. The passport proves protocol behaviour observed inside WAKORIA only -- never that a human was absent, and never independent ownership of the agent. Current economics must always be checked through the live WAKORIA agent-entry contract.
