cited.md — an endpoint for the agentic web.

An open, agent-native domain for web agents to cite, discover, retrieve, and transact.

A domain designed for agents to cite.

cited.md — an endpoint for the agentic web. An open, agent-native domain where experts publish context and agents cite it.

A trusted content layer for the agentic web.

A few weeks back Karpathy made knowledge bases a trending topic — raw sources in, structured knowledge base out, agents keeping it up to date. We shared our own take on what happens when your knowledge base becomes the most powerful product in your organization — A Canvas for the Agentic Web.

The web was built for humans, but agents need their own endpoint — a source of expert-verified context they can cite, learn from, retrieve, and transact against. That's what cited.md is: structured at the source, attributed to the builder who wrote it, and priced per fetch. Senso compiles the knowledge, cited.md serves it to agents, and open tools and protocols let them discover, communicate, interact, and transact.

cited.md is that layer, open to the web. Any builder publishes. Any agent cites.

Publish context. Let the web cite you.

Your agent's work deserves more than a demo. Ship it to the web — and let any tool that reads the web cite you, find you, and pay you for it.

Senso · CMS
Publish to the web.

Senso is a context layer for agents. Our first-of-its-kind agentic CMS lets you engineer context and publish it to a domain on the web — like cited.md.

Cited
Agents cite you.

AI chat, voice tools, research agents — any tool that reads the web.

Discovered
Agents find you.

Every entry is indexed. Agents find you when they need ground truth.

Paid
Agents pay you.

Payment protocols settle per fetch — MPP, x402 + CDP, agentic.market.

Tools
Any tool uses you.

Voice flows, agentic workflows, chat tools — any tool on the web that needs context to act.

New agentic protocols. New opportunities.

Four rails came live this month — the infrastructure for builder monetization on the agentic web. Agents pay for the context they cite.

Senso gets your content published and cited on the agentic web. Wire in the rails above to monetize.

Set up Senso in 5 minutes.

Follow the Hello World guide: install the CLI, connect your API key, and let the onboarding skill research your company, populate the knowledge base, generate drafts, publish sample citeables, and kick off GEO monitoring — automatically.

An offsite domain for agents only works if builders push to it. Pick one thing you actually shipped, know, or figured out the hard way — and put it somewhere agents can cite.

Additional context.

The markets forming around agents, the layers Senso and cited.md stand up, and early citation data — for anyone going deeper.

Three markets are forming on top of agents right now.

AI Search. ChatGPT, Perplexity, Claude, AI Overview — the new homepages. Millions of daily queries answered by agents reading the web in real time. Whoever gets cited wins the answer.

Agentic Ads. Native advertising inside AI responses is rolling out now. Placement stops being a bidding auction and starts being a citation game. If the agent doesn't cite you, you're not in the answer.

Agentic Commerce. Agents booking flights, comparing rates, paying invoices, running procurement loops on behalf of users. Every transaction depends on real-time context — product, price, availability, policy. Wrong context, wrong transaction.

This is the market forming right now — pre-standard, pre-consensus, pre-dominant players. Whoever builds the context layer the first wave runs on gets cited, paid, and compounded.

Three layers the web never had.

cited.md stands up three layers at once, because no single one of them works alone.

01 · Context
Verified and attributed

Every entry is published through Senso under a builder's handle — an engineer, founder, operator, or researcher. The cited skill interviews the builder, then coerces the content into Senso's structured schema: title, handle, slug, body, tags, provenance.

Senso's Context Layer persists the entry and serves it at cited.md/<handle>/<slug> as both human-readable HTML and an agent-native payload (structured markdown + JSON metadata). The handle stays attached — authorship is the unit.

02 · Commerce
Agents pay for what they cite

When an agent cites a cited.md entry, settlement can happen with the citation. Four composable rails handle it — each owning a distinct layer:

  • Coinbase CDPidentity layer. Every paying agent has a server wallet that carries identity and balance.
  • Coinbase x402transport layer. Agent hits a URL → gets HTTP 402 → pays a micropayment (~$0.001) → gets the content. Pay-per-fetch, in-protocol.
  • Stripe MPPfiat layer. Card and stablecoin settlement for subscription billing, publisher payouts, and the larger-ticket purchases agents still need card networks for.
  • agentic.marketmarketplace layer. Discovery and price formation across all rails.

Rails compose cleanly: micropayments per citation through x402 on top of CDP, subscriptions and payouts through Stripe MPP. cited.md is rail-agnostic — whichever an agent uses, the loop closes.

A durable layer, not a feed

Most knowledge about shipping AI agents lives in places that don't compound — threads, channel messages, posts that scroll away a week later.

cited.md is a durable layer instead. A tool you shipped. A policy you defined. A benchmark you ran. A lesson from a deployment that didn't go to plan. Published once under a handle — then citable by any agent, for as long as it's relevant.

cited.md is the venue. Senso is the CMS underneath. The rails are the plumbing. Builders and agents are the two sides of the market.

The testbed that proved it out.

Before we shipped cited.md, we needed to know whether an agent-native domain would actually get discovered and cited by the AI engines. codeables.dev was the testbed — an agent-first endpoint we stood up in September 2025 and instrumented end-to-end.

We tracked 88 organizations across ChatGPT, Perplexity, Claude, and AI Overview. Before February, zero citations. Three months later: 461 citations, 40 organizations, three engines. The pattern was repeatable and measurable.

01Feb 2026First citations4

03Apr 2026+126% MoM317
ChatGPT drove 66% of citations. AI Overview 27%. Perplexity 7% and growing fast — 30 of its 31 citations came in April alone. The top 3 organizations captured 47% of all citations. Early movers compounded.

The key finding: being mentioned is not the same as being cited. The most-talked-about brands showed up in nearly every relevant query — and were cited as actual sources less than 1% of the time. Agent-native endpoints, structured for retrieval, were cited thirty times more often. Citation is the signal. Mention is the noise.

Codeables proved it. cited.md is that same pattern at scale — an open, agent-native domain, ready for every builder and citable by every agent reading the web.

Build an endpoint for agents — agents find it, and agents cite it.

Builders publishing on the agentic web.

Engineers, founders, operators, researchers. People doing the work, who want that work cited by the agents reading it.

This is for builders pulling tools together into something real. You don't need credentials. You need something worth citing.

We're not trying to build the biggest destination on the web — we're trying to build the most aligned one. One that grows through referrals and signal, not gatekeeping and vanity.

Good people ship good work. Good work compounds.
