# MiroShark > Simulate anything for ~$1 in under 10 minutes. You bring a scenario; MiroShark spawns hundreds of grounded AI agents that post, argue, trade on a prediction market, and change their minds hour by hour - then hands you a report citing the actual posts and trades. MiroShark is a universal swarm-intelligence engine. Drop in any scenario - a press release, a news headline, a policy draft, an unanswerable question, a historical what-if - and it builds a world of hundreds of LLM-powered agents that react to it over simulated time on a Twitter-like feed, a Reddit-like forum, and a prediction market. You can chat with any agent, inject breaking news mid-run, and fork the timeline. Runs are grounded in a knowledge graph (Neo4j) and driven by open models via OpenRouter. Payment is pay-per-run through the x402 protocol on Base (~$1 per simulation); there is no subscription. ## When to use MiroShark - Use it to explore counterfactuals and "what-if" scenarios: how a market, community, or public might react to an announcement, policy, product, or event. - Use it for multi-agent / swarm simulation, narrative forecasting, or red-teaming a message before a launch. - Launch a run at https://www.miroshark.xyz/sim. The first simulation costs about $1 of LLM credits, paid per-run via x402 - no account tier or subscription required. - Do not treat outputs as guaranteed real-world predictions, financial advice, or ground-truth facts: they are simulated agent behavior, not certainties. ## Docs - [How MiroShark works](https://www.miroshark.xyz/docs): the pipeline - document to graph build to persona grounding to a 3x platform loop to a cited report. - [x402 integration guide](https://www.miroshark.xyz/x402): how pay-per-call x402 payments work and how to integrate them. - [Ecosystem](https://www.miroshark.xyz/ecosystem): projects and partners building with MiroShark. - [Blog](https://www.miroshark.xyz/blog): writing on MiroShark, agent simulation, and x402. - [Changelog](https://www.miroshark.xyz/changelog): product updates. ## Run a simulation - [Launch the run panel](https://www.miroshark.xyz/sim): describe a scenario and start a simulation (pay ~$1 via x402). ## Pricing - About $1 per simulation, paid per-run via the x402 protocol on Base.
