Twenty-three pre-curated, protocol-grade ENS namespaces covering every architectural function in modern API infrastructure — protocol layer at the top, key authority and credential issuance, routing and rate limiting, monitoring and analytics, service discovery and quota enforcement. The agent-economy stack. The naming layer for the agent economy taking shape around protocol APIs. Every name scored, classified, with on-chain coverage advancing every batch.
Twenty-three names organized by function. From the protocol layer down through key authority, credential issuance, routing, rate limiting, monitoring, analytics, and service discovery. Each name has a distinct architectural role. Click any name to view its full registry page.
The agent economy needs API infrastructure that's verifiable, decentralized, and machine-readable. Most teams pick generic names ad-hoc, with no semantic layer or on-chain classification. A curated stack solves all of it.
Yes. Each name is independently lease-eligible. The "full stack" framing is for teams who want all twenty-three at once — you're not locked in. Most teams start with the protocol + key-authority + credential triangle (apiprotocol, apikeyauthority, apicredential) and add components over time.
You get exclusive subdomain rights under the parent name (e.g., your project becomes myco.apiprotocol.eth) plus the ability to mint additional subdomains as your infrastructure grows. The parent name stays in the registry — you don't buy the parent, you lease the subdomain space.
You can. But you'd be naming your stack from scratch, with no semantic layer, no taxonomy, no on-chain classification. These names already have the records, the curation, and the documentation. They drop into a builder's mental model as "primitives" rather than "I made up a name."
ENSv2 launches the subdomain-leasing primitives we'd use for full automation. ENS team has stated 2026 launch is on track ↗. Until then, leases are pre-arranged via direct contact. Reserve now to be in the first batch.
No. CPR has 44 ontological stacks across the portfolio of over 2,750 names. The other Featured Stacks: ZK Rollup Stack, Oracle Network Stack, Identity Stack, Restaking Stack, and MEV Defense Stack. Browse all 15 verticals or the full registry.
The teams shipping API and agent-economy infrastructure — protocol APIs, key authorities, credential issuance, routing, monitoring, agent gateways. As leases activate, this section will list who’s building on which namespace. If you’re running protocol API or agent infrastructure and want a slot here, get in touch.
