# Particle Data Platform

> Particle Data Platform is a B2B data platform that exposes real-time news, financial data, and podcast intelligence as a single API for developers, brands, and AI agents.

Particle is operated by Mina Labs, Inc. The product is sold to developers building agentic and analytical applications, brands and advertisers measuring earned media and podcast mentions, and quantitative teams sourcing alternative data.

## AI agents

Start with the setup playbook. It is the one document that takes an agent from nothing to a working connection and a first live query.

- [Agent setup playbook (agents.md)](https://api.particle.pro/agents.md): Skill-formatted instructions for connecting a client over MCP, the REST API, or x402, and running a first query. Signposted from https://particle.pro/agents.md.
- [Endpoint and tool map (llms.txt)](https://api.particle.pro/llms.txt): Every REST endpoint and MCP tool with its per-call price, plus the shared request conventions.
- [Agent authentication recipe (auth.md)](https://particle.pro/auth.md): How an agent obtains credentials, or pays per request with no account at all.
- [Pay per request with x402](https://docs.particle.pro/x402): A keyless call to any billable endpoint returns 402 with USDC payment terms on Base; pay and retry. No signup, no key.
- [x402 manifest](https://particle.pro/.well-known/x402): Machine-readable list of payable REST and MCP resources (draft-hawkins-x402-dns-discovery); also published as [x402.json](https://particle.pro/.well-known/x402.json).
