Register an OAuth client to obtain client_id and client_secret. Run the OAuth2/OIDC authorization code flow (PKCE recommended). Start an LNURL-Auth session for Lightning wallet login. Verify JWTs with the JWKS endpoint. ### 1) Configure the base URL Set the base URL to the HODLXXI deployment (update as needed): BASE_URL="https://hodlxxi.com" ### 2) Register an OAuth client Register a client to get credentials: curl -X POST "$BASE_URL/oauth/register" \\ -H "Content-Type: application/json" \\ -d '{"client_name": "YourAgentName", "redirect_uris": ["https://your-callback-url"], "scopes": ["openid", "profile"]}' Store client_id and client_secret securely. ### 3) Run OAuth2/OIDC authorization code flow Discover endpoints: curl "$BASE_URL/.well-known/openid-configuration" Create an authorization request (PKCE recommended): curl "$BASE_URL/oauth/authorize?client_id=your_client_id&redirect_uri=your_callback&response_type=code&scope=openid%20profile&code_challenge=your_challenge&code_challenge_method=S256" Exchange the authorization code for tokens: curl -X POST "$BASE_URL/oauth/token" \\ -H "Content-Type: application/x-www-form-urlencoded" \\ -d "grant_type=authorization_code&code=received_code&redirect_uri=your_callback&client_id=your_client_id&code_verifier=your_verifier" Expect an access token, ID token (JWT), and optional refresh token. ### 4) Start an LNURL-Auth session Create a session and show the LNURL to the user: curl -X POST "$BASE_URL/api/lnurl-auth/create" \\ -H "Accept: application/json" Poll for completion after the user scans the LNURL with a Lightning wallet: curl "$BASE_URL/api/lnurl-auth/check/your_session_id" ### 5) Verify JWTs Fetch JWKS: curl "$BASE_URL/oauth/jwks.json" Verify with Python (example uses PyJWT): import jwt import requests jwks = requests.get("https://your-hodlxxi-deployment.com/oauth/jwks.json", timeout=10).json() public_key = jwt.algorithms.RSAAlgorithm.from_jwk(jwks["keys"][0]) claims = jwt.decode(your_jwt, public_key, algorithms=["RS256"], audience="your_audience") print(claims) ### 6) Monitor health and metrics Check liveness and OAuth system status endpoints: curl "$BASE_URL/health" curl "$BASE_URL/oauthx/status" ### Register a client from a JSON template curl -X POST "$BASE_URL/oauth/register" \\ -H "Content-Type: application/json" \\ -d @templates/oauth-client.json ### Create LNURL session and poll session_json=$(curl -s -X POST "$BASE_URL/api/lnurl-auth/create") session_id=$(python3 -c 'import json,sys; print(json.loads(sys.argv[1])["session_id"])' "$session_json") curl "$BASE_URL/api/lnurl-auth/check/$session_id" ### Best practices Always use HTTPS and verify TLS certificates in production. Keep client secrets in a secrets manager or environment variables. Use PKCE for public clients and rotate secrets for confidential clients. Treat LNURL sessions as single-use and enforce short TTLs. Validate aud, iss, and exp claims for JWTs. ### Advanced features Use /oauthx/docs for live OAuth/OIDC API documentation. Use /oauthx/status to monitor database and LNURL session health. Rotate JWKS keys via the server configuration (JWKS directory + rotation days). ### PAYG billing for OAuth clients Paid API calls are billed per OAuth client_id (agent/app), not per session pubkey. When balance or free quota is exhausted, paid endpoints return HTTP 402 with a Lightning top-up path. ### Billing endpoints (OAuth token required) POST /api/billing/agent/create-invoice POST /api/billing/agent/check-invoice Example create invoice: curl -X POST "$BASE_URL/api/billing/agent/create-invoice" \\ -H "Authorization: Bearer $ACCESS_TOKEN" \\ -H "Content-Type: application/json" \\ -d '{"amount_sats": 1000}' Example check invoice: curl -X POST "$BASE_URL/api/billing/agent/check-invoice" \\ -H "Authorization: Bearer $ACCESS_TOKEN" \\ -H "Content-Type: application/json" \\ -d '{"invoice_id": "your_invoice_id"}' ### 402 response shape When a paid endpoint is called with insufficient balance, expect: { "ok": false, "error": "payment_required", "code": "PAYMENT_REQUIRED", "client_id": "your_client_id", "cost_sats": 1, "balance_sats": 0, "create_invoice_endpoint": "/api/billing/agent/create-invoice", "hint": "Top up via Lightning PAYG" } ### Supporting files scripts/verify_signature.py validates LNURL-Auth signatures locally. HEARTBEAT.md describes periodic health checks for the deployment. templates/oauth-client.json provides a ready client registration payload. ### Optional helper script Use scripts/verify_signature.py to validate LNURL signatures locally. Install the dependency first: python -m pip install ecdsa python scripts/verify_signature.py --k1 --signature --pubkey ## Trust - Source: tencent - Verification: Indexed source record - Publisher: hodlxxi - Version: 0.1.0 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-04-23T16:43:11.935Z - Expires at: 2026-04-30T16:43:11.935Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/hodlxxi-bitcoin-identity) - [Send to Agent page](https://openagent3.xyz/skills/hodlxxi-bitcoin-identity/agent) - [JSON manifest](https://openagent3.xyz/skills/hodlxxi-bitcoin-identity/agent.json) - [Markdown brief](https://openagent3.xyz/skills/hodlxxi-bitcoin-identity/agent.md) - [Download page](https://openagent3.xyz/downloads/hodlxxi-bitcoin-identity)
