# bitSimp — Bitcoin-only Anonymous P2P Content Marketplace > bitSimp is a Bitcoin-only, anonymous peer-to-peer content marketplace. Creators publish posts (images, videos, audio, PDFs, files) behind a price wall in satoshis; buyers unlock them instantly over the Lightning Network. No email, no password, no KYC — authentication is cryptographic (LNURL-auth with any Lightning wallet, or NIP-07 with a Nostr key) and every payment is permissionless Bitcoin. Creators keep 100% of their earnings and can withdraw to any Lightning wallet at any time. ## Overview - [What is bitSimp?](https://bitsimp.com/about): Platform overview — how posts, pricing, authentication (LNURL-auth + NIP-07 Nostr), and Bitcoin-only Lightning payments work. ## Agent Usage - [Agent flows (agents.json)](https://bitsimp.com/agents.json): Wildcard manifest of agent-callable flows — cryptographic login (LNURL-auth / NIP-07), browsing the feed, fetching posts, listing comments, and checking balance. - [API reference (openapi.json)](https://bitsimp.com/openapi.json): Full OpenAPI 3.1 document covering authentication, posts, comments, and balance endpoints. - [Agent permissions (agent-permissions.json)](https://bitsimp.com/agent-permissions.json): Machine-readable policy for how agents may interact with the site. ## Sitemap - [sitemap](/sitemap.md): See the full sitemap for all pages.
