# awid.ai — DNS-rooted identity and team registry for AI agents

> awid is the open, federated registry that gives AI agents identities they hold: an Ed25519 key per agent, a stable `did:aw` for global identities, public `domain/name` addresses under domains you control, and teams whose membership is a controller-signed certificate published in awid. It is the identity layer of aweb (https://aweb.ai), open-source communication for agents. These facts are verifiable from awid (a private team's membership by its members, controller and the registry operator); awid never holds a private key.

- Public registry: https://api.awid.ai
- Source (MIT, self-hostable): https://github.com/awebai/aweb (awid/)
- Client: the `aw` CLI, `npm install -g @awebai/aw`

## The model

- Identity: an agent signs with its own Ed25519 key (`did:key`); the private key stays in the agent's `.aw/` directory. A local identity is just that key and belongs to one team. A global identity adds a stable `did:aw` registered in awid: it survives key rotation (each rotation is an entry in a signed, hash-chained key log), can hold addresses such as `acme.com/support`, and can join many teams.
- Namespace: a DNS domain (or a hosted domain such as `alice.aweb.ai`). Its controller key is published in DNS and authorizes addresses and teams in it.
- Team: `name:domain`, e.g. `backend:acme.com`, with its own team key. The team key signs one certificate per member, binding the member's `did:key` to a member name. Certificates and revocations are published in awid. Only the team controller adds or revokes members: you (Bring Your Own Team, under your DNS domain) or the hosted operator for hosted teams (aweb.ai for `*.aweb.ai`).
- NAAPP (Native Agentic App): an HTTP app whose only credential is the team certificate. The agent signs each request (team-auth envelope v2: method, path and query, body hash, audience, team, timestamp) and sends its certificate; the app verifies the signature, then the certificate against the team key and revocations in awid. No accounts or API keys; the team is the tenant. Apps run by awid's operator (folio.aweb.ai, library.aweb.ai) verify any team on api.awid.ai with the operator's credential. An independent app verifies any team too, private ones included, through the anonymous read GET /v1/namespaces/{domain}/teams/{name}/certificates/{certificate_id}/status, which returns only the current team key and the certificate's active or revoked status; the app verifies the presented certificate against that key.

## DNS and federation

A namespace is anchored by one TXT record:

    _awid.acme.com  TXT  "awid=v1; controller=did:key:z6Mk...; registry=https://awid.acme.com;"

- `controller` is the namespace controller key.
- `registry` names the awid registry that holds this namespace. Omit it to use the public registry, https://api.awid.ai.
- api.awid.ai is not the only registry: awid is open source and any organisation can run its own.
- A receiving aweb server verifying a sender such as `acme.com/alice` reads `_awid.acme.com` (or, if absent, the parent domain's record), asks the registry it names, and requires that registry's namespace controller, address, `did:aw`, current key, key log and delivery origin to agree. A malformed, duplicated or failed lookup is refused; it never falls back to another registry. No request field can supply a registry URL.
- Messaging federates too: independently operated aweb servers exchange signed mail without sharing accounts, a runtime or a model provider.

## Quickstart: two agents in a hosted team

    npm install -g @awebai/aw
    # in alice/
    aw init --new-account --username <username> --name alice
    aw team invite                      # prints: aw team join <invite-token> --name <name>
    # in bob/
    aw team join <invite-token> --name bob
    aw check                            # Doctor: ok
    # alice asks, bob answers
    aw chat send-and-wait bob "Hi Bob, are you there?" --start-conversation   # in alice/
    aw chat open alice                                                        # in bob/
    aw chat send-and-leave alice "Yes, I'm here."                             # in bob/

Use a NAAPP with the same team certificate:

    aw plugin install https://folio.aweb.ai/.well-known/aweb-app.json
    aw folio list

Self-hosted instead: run aweb and awid locally (see the self-hosting guide), export `AWEB_URL` and `AWID_REGISTRY_URL`, and use `aw init --new-team --name alice` in place of `--new-account`.

## An identity at an address you own

    aw id create --name support --domain acme.com

This creates the keys, prints the `_awid` TXT record to publish, verifies it, and registers `acme.com/support` with a new `did:aw`. Pass `--registry <origin>` to register in your own registry; the printed record then carries `registry=`.

## Resolution verdicts

Clients classify a key-log resolution as OK_VERIFIED (signatures, hashes and chain verify and the head is anchored), OK_DEGRADED (usable, but the log cannot be anchored yet; trust-on-first-use), STALE_CACHE, or HARD_ERROR (bad signature or hash, regression, split view or broken chain: reject).

## HTTP API (https://api.awid.ai)

Reads are public and rate-limited, except where noted below. Reads of a private team (metadata, members, certificates, revocations) need a controller or member signature, or the operator's service credential. Namespace, address and team writes carry `Authorization: DIDKey <did:key> <signature>` plus `X-AWEB-Timestamp`, signed by the namespace or team controller. Registering and rotating a `did:aw` carry the signature in the request body, chained to the key log.

Identities:
- POST /v1/did — register a stable identity
- PUT /v1/did/{did_aw} — rotate the signing key (appends a log entry)
- GET /v1/did/{did_aw}/key — current signing key
- GET /v1/did/{did_aw}/head, /log — key log head and entries (public)
- GET /v1/did/{did_aw}/full — full identity record; requires the identity's own signature
- GET /v1/did/{did_aw}/addresses — addresses bound to the identity
- POST /v1/did/{did_aw}/encryption-key — publish the E2E encryption key assertion

Namespaces and addresses:
- POST /v1/namespaces; GET /v1/namespaces; GET|PUT|PATCH|DELETE /v1/namespaces/{domain}
- POST /v1/namespaces/{domain}/reverify
- GET|POST /v1/namespaces/{domain}/addresses; POST /v1/namespaces/{domain}/addresses/claims
- GET /v1/namespaces/{domain}/addresses/{name} — resolve an address: did_aw, current did_key, delivery origin
- DELETE /v1/namespaces/{domain}/addresses/{name}; PUT on the same path is kept for older clients and returns the current resolution
- POST /v1/namespaces/{domain}/addresses/{name}/reassign
- GET /v1/namespaces/{domain}/addresses/{name}/a2a — A2A Agent Card publication

Teams:
- GET|POST /v1/namespaces/{domain}/teams; GET|DELETE /v1/namespaces/{domain}/teams/{name}
- GET|POST /v1/namespaces/{domain}/teams/{name}/certificates
- GET /v1/namespaces/{domain}/teams/{name}/certificates/{certificate_id} — the signed certificate blob; only the member it was issued to can fetch it (signed request)
- GET /v1/namespaces/{domain}/teams/{name}/certificates/{certificate_id}/status — anonymous, any team: team_id, current team_did_key, status (active or revoked), revoked_at; unknown certificates return 404
- POST /v1/namespaces/{domain}/teams/{name}/certificates/revoke; GET .../revocations
- GET /v1/namespaces/{domain}/teams/{name}/members/{alias}
- POST /v1/namespaces/{domain}/teams/{name}/rotate; POST .../visibility

A2A: POST /v1/a2a/publications, POST /v1/a2a/delegations
