Verification Methods

Manage DID verification methods (P-256 keypairs) used for attestation signing and PLC operations.

TypeScript

const TOKEN = "hv_..."; // your API key
const headers = { Authorization: `Bearer ${TOKEN}` };

JavaScript

const TOKEN = "hv_..."; // your API key
const headers = { Authorization: `Bearer ${TOKEN}` };

Rust

let token = "hv_..."; // your API key

Go

token := "hv_..." // your API key

cURL

# All examples assume $TOKEN is an API key (hv_...)
AUTH="Authorization: Bearer $TOKEN"

List verification methods

GET /admin/verification-methods

Requires settings:manage permission.

TypeScript

interface VerificationMethod {
  id: string;
  fragment_id: string;
  key_type: string;
  public_key_multibase: string;
  created_at: string;
}

const response = await fetch("http://127.0.0.1:3000/admin/verification-methods", {
  headers,
});
const data: VerificationMethod[] = await response.json();

JavaScript

const response = await fetch("http://127.0.0.1:3000/admin/verification-methods", {
  headers,
});
const data = await response.json();

Rust

let response = client
    .get("http://127.0.0.1:3000/admin/verification-methods")
    .bearer_auth(token)
    .send()
    .await?;
let data: serde_json::Value = response.json().await?;

Go

req, _ := http.NewRequest("GET", "http://127.0.0.1:3000/admin/verification-methods", nil)
req.Header.Set("Authorization", "Bearer "+token)
resp, err := http.DefaultClient.Do(req)

cURL

curl http://127.0.0.1:3000/admin/verification-methods -H "$AUTH"

Response: 200 OK

[
  {
    "id": "550e8400-e29b-41d4-a716-446655440000",
    "fragment_id": "#attestation",
    "key_type": "Multikey",

    "created_at": "2026-06-27T00:00:00Z"
  }
]

Create a verification method

POST /admin/verification-methods

Requires settings:manage permission. Generates a new P-256 keypair. The private key is encrypted at rest with AES-256-GCM using TOKEN_ENCRYPTION_KEY.

TypeScript

const response = await fetch("http://127.0.0.1:3000/admin/verification-methods", {
  method: "POST",
  headers: {
    ...headers,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    fragment_id: "#attestation",
  }),
});
const data: VerificationMethod = await response.json();

JavaScript

const response = await fetch("http://127.0.0.1:3000/admin/verification-methods", {
  method: "POST",
  headers: {
    ...headers,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    fragment_id: "#attestation",
  }),
});
const data = await response.json();

Rust

let response = client
    .post("http://127.0.0.1:3000/admin/verification-methods")
    .bearer_auth(token)
    .json(&serde_json::json!({
        "fragment_id": "#attestation"
    }))
    .send()
    .await?;
let data: serde_json::Value = response.json().await?;

Go

body := bytes.NewBufferString(`{"fragment_id": "#attestation"}`)
req, _ := http.NewRequest("POST", "http://127.0.0.1:3000/admin/verification-methods", body)
req.Header.Set("Authorization", "Bearer "+token)
req.Header.Set("Content-Type", "application/json")
resp, err := http.DefaultClient.Do(req)

cURL

curl -X POST http://127.0.0.1:3000/admin/verification-methods \
  -H "$AUTH" \
  -H "Content-Type: application/json" \
  -d '{"fragment_id": "#attestation"}'

Field	Type	Required	Description
fragment_id	string	yes	DID document fragment identifier, must start with # followed by alphanumerics or underscores

Response: 201 Created

{
  "id": "550e8400-e29b-41d4-a716-446655440000",
  "fragment_id": "#attestation",

}

Delete a verification method

DELETE /admin/verification-methods/{fragment_id}

Requires settings:manage permission.

TypeScript

const response = await fetch(
  "http://127.0.0.1:3000/admin/verification-methods/attestation",
  { method: "DELETE", headers },
);

JavaScript

const response = await fetch(
  "http://127.0.0.1:3000/admin/verification-methods/attestation",
  { method: "DELETE", headers },
);

Rust

client
    .delete("http://127.0.0.1:3000/admin/verification-methods/attestation")
    .bearer_auth(token)
    .send()
    .await?;

Go

req, _ := http.NewRequest("DELETE",
  "http://127.0.0.1:3000/admin/verification-methods/attestation", nil)
req.Header.Set("Authorization", "Bearer "+token)
resp, err := http.DefaultClient.Do(req)

cURL

curl -X DELETE http://127.0.0.1:3000/admin/verification-methods/attestation \
  -H "$AUTH"

The fragment_id path parameter is the identifier without the leading # (e.g. attestation for #attestation).

Response: 204 No Content. Returns 404 Not Found if no method with that fragment ID exists.
