Sits on top of x402 + ERC-8004

CommandLayer is the semantic verb & schema layer for agents.

Agents speak. x402 moves money. ERC-8004 helps you find agents. CommandLayer defines what they do.

A small, stable set of Commons verbs you can drop in today.
The first Commercial verbs for economic flows (authorize, checkout, purchase, ship, verify).
A growing Manifest of reserved future verbs for the agent economy.
Agent Cards bound to ENS and x402 so agents can advertise capabilities in a shared language.

All schemas are permanently free — the economics live in execution, not in the verb language. Each verb’s request/receipt schema is pinned to IPFS, checksummed, and anchored to its canonical ENS name.

What you can do right now

CommandLayer is the language contract between clients and agents — the part that standardizes exit names, request shapes, and receipts on top of x402.

Pick a Commons verb (e.g. summarize).
Validate payloads against the pinned, free schemas.
Describe your agent with an Agent Card so it can be discovered and routed to.
As x402 / ERC-8004 rails and Runtime endpoints come online, you keep the same contracts — only the execution layer changes.

// summarize.request

{
  "verb": "summarize",
  "content": "CommandLayer defines what agents do on x402."
}

// summarize.receipt

{
  "result": "Semantic verb layer describing agent behavior on x402.",
  "trace": "bafybeieoynknza..."
}

Real verbs, real receipts — the same shapes across agents, runtimes, and payment rails. See it live →

How the semantic layer is structured

You don’t need everything to start. One verb + its schemas is enough. As x402 and ERC-8004 roll out, the same vocabulary stretches across more agents, networks, and payment rails — without changing your contracts. All schemas are pinned to IPFS with published checksums and bound to canonical ENS verbs, so the language stays stable even as runtimes and economics change. CommandLayer doesn’t compete with x402 or ERC-8004 — it completes the stack by defining machine intent.

Commons

10 universal verbs for analysis, retrieval, summarization, and formatting. MIT-licensed, pinned to IPFS with published checksums, and treated as semantic public goods. Schemas are free forever.

View Commons verbs →

Commercial

Economic verbs for moving value: authorize, checkout, purchase, ship, and verify. A separate tier that builds on Commons semantics and fits cleanly inside x402 payment envelopes.

View Commercial verbs →

Agent Cards

JSON descriptors that tie ENS names to verbs, schema versions, and x402 entrypoints so registries and clients can discover, rank, and route to your agent — without guessing how it’s wired.

Manifest

Tier 2 verb portfolio — 200+ reserved verbs for AI, commerce, finance, operations, and comms. The canonical map of future machine intent CommandLayer will standardize; not all verbs are live yet, but the namespace is staked out.

Runtime coming online

Execution & guarantees for every verb — where paid flows, routing decisions, and SLAs live, reusing the same free schemas so semantics stay stable while economics evolve. Runtime expands into x402 rails as they land.

Roadmap

See what’s already pinned and what’s next: expanded Commons verbs, additional Commercial flows, more Agent Cards, and the Runtime layer rolling out alongside x402 and ERC-8004 adoption.

Start with `summarize`

See a complete example: build a summarize.request, validate it with JSON Schema 2020-12, and receive a summarize.receipt from an agent — all using the Commons v1.0.0 contracts.

Start with one verb. As x402 and ERC-8004 adoption grows, the same free schemas and Agent Cards scale across more agents, runtimes, and payment rails.
