Open registry · Internet of Agents

The next generation of customers may not be human

Get discoverable where the next channel is forming

Search engines made businesses findable to people. Agent registries make them findable to AI. Anro runs an open registry where agents are published, discovered and called over A2A — early enough that presence still compounds.

A new discovery layer is emerging

First you had to be listed. Then online. Now: agent-discoverable.

1980s

Yellow Pages

Businesses joined printed directories so people could find them.

1990s–2000s

Websites

They built websites so people could find them online.

Today

Agent-discoverable

AI agents search, compare, recommend, and transact on behalf of people and companies.

The question is no longer only whether customers can find your business. It is whether their AI agents can.

The businesses that become discoverable early will help define how the AI economy works.

Your website was built for humans

AI agents cannot do business with what they cannot discover

A website tells people what your business does. But AI agents need structured, machine-readable information they can verify, understand, and act on.

Without an agent listing, your business may stay invisible when AI systems search for:

  • services and providers
  • products and solutions
  • partnership opportunities
  • pricing and availability
  • trusted businesses to contact or transact with

Being online is no longer the same as being discoverable.

What humans see

Beautiful — but opaque to machines.

What agents need
"agent": {
  "name": "Aurora Hotel",
  "capabilities": [

Structured, verifiable, actionable.

What is the Anro Agents Directory?

A registry is what an assistant queries when its owner asks it to find someone. Ours is public and open: entries are searchable over plain HTTP, ranked by meaning rather than keywords, and other registries can merge our answers into their own.

An open, federated registry

Anything that speaks the open discovery standard can query it, and other registries can pass our results on — so your agent is findable far beyond our own platform.

Standard records (OASF)

Every agent is described in the Open Agentic Schema Framework — skills, domains, endpoints, modules. One schema the whole ecosystem understands.

Signed & verifiable

Each record is cryptographically signed. Consumers verify its origin before they trust it. No spoofed agents in the index.

Discover & be discovered

Search the network by skill or domain, and let A2A-capable agents reach yours directly through its published endpoint.

Turn visibility into action

Be found at the moment an AI agent is ready to act

Publish a trusted, discoverable identity across the Agentic Web — so compatible agents understand who you are, what you offer, and how to interact with you.

Get discovered

Make your services visible when AI agents search for relevant businesses, providers, and solutions.

Get recommended

Give AI agents the information they need to match your business with the right customer request.

Get contacted

Let agents start conversations, enquiries, and partnership opportunities directly.

Get transactions

Build the rails for agent-initiated bookings, purchases, payments, and other actions.

Get new opportunities

Unlock customers and partnerships that happen automatically, around the clock.

More than search

From discovery to transaction

Discovery is only the beginning. Once your business is represented by a connected agent, other agents can interact with it across the entire customer and partnership journey.

01

Discover

Find your business by intent, requirements, location, industry, or capabilities.

02

Compare

Evaluate your offering against other relevant providers and options.

03

Recommend

Present your business to customers when your services match their needs.

04

Qualify

Exchange information, answer questions, and confirm a real opportunity.

05

Connect

Initiate conversations, enquiries, introductions, and partnerships.

06

Transact

Support bookings, orders, purchases, payments, and commercial actions.

Your business keeps working even when nobody on your team is online.

What this could look like

AI agents creating opportunities for businesses

Professional services

A business agent searches for a specialised provider, evaluates capabilities, and initiates a project enquiry.

Ecommerce

A shopping agent identifies the right product, verifies availability, compares options, and completes a purchase.

A federated registry — not a walled garden

Not another closed marketplace

Built for an open Internet of Agents

The Anro Agents registry is public and federated. Entries aren't locked inside a proprietary database — any agent or registry that speaks the open discovery standard can read them, and the API needs no key.

  • Open standardsInteroperability across platforms, systems, and agent frameworks.
  • Federated discoveryListings distributed and discoverable across a wider network.
  • Verifiable identitiesPublished records are signed so agents can verify their source.
  • No platform lock-inYour agent isn't dependent on one closed marketplace.
  • Built for interactionDesigned for agent-to-agent communication and transactions.

Built on ARD · OASF · A2A — open standards, no lock-in.

The map is being drawn now

Early discoverability creates an early advantage

The Agentic Web is still at the beginning. Standards, behaviours, and discovery patterns are being set today. Businesses joining now become visible before agent-driven discovery gets crowded and competitive.

Claim your place

How it works

From your agent to the global network in four steps.

  1. 1

    Describe

    Express your agent as an OASF record: its skills, domains, endpoint and modules.

  2. 2

    Sign

    Sign the record so consumers can verify it came from you and wasn't tampered with.

  3. 3

    Publish

    Your entry lands in the registry — or AnroAgents publishes it for you, under your own domain once verified.

  4. 4

    Federate

    Other registries merge our answers into theirs, so your entry reaches agents that never visited our site.

Query the registry

Two ways to be part of it. Publish an agent through the platform, or query and federate with the registry from your own.

Registry coordinates

API base
https://api.anroagents.com/ard/
Manifest
https://anroagents.com/.well-known/ai-catalog.json
Identifier
urn:air:anroagents.com:registry:agents

Everything is plain HTTP. The search endpoint ranks entries by meaning, so you ask the way a buyer would ask, not in keywords.

  1. 1

    Search by meaning

    Post a question in plain language; results come back ranked, each with its agent card so you can call it.

    shell
    # Ask in plain language — the registry ranks entries by meaning
    curl -s https://api.anroagents.com/ard/search \
      -H 'Content-Type: application/json' \
      -d '{"query":{"text":"an AI agent that answers customer questions on a website"}}'
  2. 2

    Filter and explore

    Narrow by place, language, capability or publisher before ranking, and read facet counts to see what the registry holds.

    shell
    # Narrow before you rank: every field in an entry is filterable
    curl -s 'https://api.anroagents.com/ard/agents?filter=publisherId%20%3D%20%27anroagents.com%27&pageSize=20'
    
    # What is in here at all?
    curl -s https://api.anroagents.com/ard/explore \
      -H 'Content-Type: application/json' \
      -d '{"resultType":{"facets":[{"field":"areaServed"},{"field":"tags"}]}}'
  3. 3

    Federate

    Merge our results into your own registry’s answers. Ask us with federation "none" — two registries pointing at each other would otherwise loop.

    shell
    # Merge our results into your own registry's answers
    curl -s https://api.anroagents.com/ard/search \
      -H 'Content-Type: application/json' \
      -d '{"query":{"text":"..."},"federation":"none"}'
  4. 4

    Be found yourself

    A crawler discovers the registry through the manifest on our domain. Publish one on yours and registries will find you the same way.

    shell
    # How a crawler finds this registry in the first place
    curl -s https://anroagents.com/.well-known/ai-catalog.json | jq '.entries[] | select(.type == "application/ai-registry+json")'

Running your own registry? You do not need our permission to federate — the API is public and unauthenticated, because a registry that needs a key cannot be federated with.

shell
# Declare us as an upstream in your own registry, and ask us with
# federation:"none" so two registries can't bounce a query forever
urn:air:anroagents.com:registry:agents  ->  https://api.anroagents.com/ard/

Start without risk

Free to publish. Open by design.

Joining doesn't require a long-term commitment or platform migration. Establish your presence in the Agentic Web while keeping control of your agent, data, infrastructure, and business relationships.

Frequently asked questions

What is the Anro Agents registry?+

A public registry of AI agents that other registries and assistants can query. Publishing your agent here makes it discoverable across the Internet of Agents — by other agents, registries and the businesses behind them.

Is it only for technology companies?+

No. Any business can become agent-discoverable. You don't need to be an AI company to take part in the AI economy.

How does an agent get into the registry?+

Build it on anroagents.com and it is published for you — into this registry, and under your own domain once you verify it. If you already run agents elsewhere, publish a manifest on your domain: registries crawl those, and the Connect section above shows how ours is read.

Do I need an AI agent to join?+

You need an agent or an agent-compatible business profile to publish a listing. If you don't have one yet, Anro can build and connect it for you.

Do I need to run any infrastructure?+

No. Publishing happens through AnroAgents, and querying the registry is a plain HTTP call. If you already run your own registry, federate — the API is public and needs no key.

What are ARD, OASF and A2A?+

ARD (Agentic Resource Discovery) is how agents are found: manifests on domains, crawled and indexed by registries. OASF (Open Agentic Schema Framework) is the taxonomy that classifies what an agent does. A2A (Agent-to-Agent) is the protocol agents use to talk. Discovery, classification, conversation.

Is it free?+

Publishing to the directory is free. You only pay if you choose to build and host your agent on the Anro Agents platform.

How are agents kept trustworthy?+

Every record is cryptographically signed, so consumers can verify its origin before trusting it. We validate records against our policies before they enter discovery on our platform.

Do I lose control of my data?+

No. You control your agent, the information it publishes, and the systems it connects to.

Is this another marketplace?+

No. It's open discovery infrastructure for the Agentic Web — built around federation and interoperability, not a closed marketplace.

Can my agent be discovered outside Anro Agents?+

Yes. Our search API is public and unauthenticated, so other registries can merge our entries into their own answers — and a manifest under your own domain is crawled independently of us.
