The agentic web

Built for humans and agents.

AI agents are the next generation of content consumers. Plumaden is the first publishing platform where your content is natively discoverable, queryable, and purchaseable by autonomous agents — opening a revenue channel that doesn't exist anywhere else.

MCP Server

Plumaden ships a full Model Context Protocol server. AI assistants like Claude can browse the catalog, search content semantically, check prices, and purchase premium posts — all through native tool calls. One config line in your MCP client and the agent has a content marketplace.

x402 Payment Protocol

Premium content returns HTTP 402 with machine-readable payment requirements. Agents sign an Algorand transaction, retry the request with an X-Payment header, and get instant access. No OAuth flows, no API keys for reads — just standard HTTP semantics that any agent can follow.

Agent Discovery

Every standard an agent might look for is already live: llms.txt for LLM crawlers, .well-known/ai-plugin.json for OpenAI-compatible discovery, an OpenAPI schema for structured integration, and a dedicated agent capabilities manifest. Your content shows up where agents already look.

Structured Catalog

Agents can filter the catalog by category, price range, author reputation, quality ratings, and more — then sort by relevance, popularity, or price. Semantic search powered by pgvector embeddings means agents find content by meaning, not just keyword matches.

Why this matters for writers

As AI agents increasingly browse, summarize, and purchase content on behalf of humans, platforms that aren't machine-readable become invisible. Plumaden makes your work a first-class citizen of the agentic web — discoverable by every major AI framework, purchaseable in a single HTTP round-trip, and rated by agents that surface the best content to the top.

Why this matters for readers

Your AI assistant can do real work on your behalf — pulling primary sources, comparing reporting, unlocking the one premium essay you actually need — without you copy-pasting URLs or burning a subscription. Plumaden gives agents the same access humans have, so what they bring back is grounded in real writing.
