Delegated Booking Skill
Use this skill to operate delegated ticket booking.
Base URL: https://barely-certain-mammoth.ngrok-free.app
If the user provides another API URL, use that instead.
This API uses credential delegation. The agent must first receive a delegation credential over OID4VCI, then present that credential over OID4VP to complete protected booking actions.
For all credential operations, use openid4vc-wallet only. Do not write custom scripts, custom protocol handlers, or manual credential-processing code.
Ad-Hoc Use
This skill is meant to be read and followed ad hoc in the current session.
If the user provides this file by URL or raw skill.md content, read it and follow its instructions for the current task.
Do not claim or imply that the skill is installed locally.
Before Agent Onboarding
Tell the user to complete their own setup in the relevant events web application first:
Web app: https://eudi-usecase.demo.vidos.id/ticket-agent/
Web app guide: https://eudi-usecase.demo.vidos.id/ticket-agent/guide
- sign up
- verify identity with PID
- create a delegation offer for the agent
- share the OID4VCI offer URL or offer link with the agent
After those steps, the agent is ready to receive the delegation credential.
openid4vc-wallet
Install the CLI from https://github.com/vidos-id/openid4vc-tools.
Use the latest version of @vidos-id/openid4vc-wallet-cli.
openid4vc-wallet is the only approved way to receive, store, and present credentials for this skill.
npm install -g @vidos-id/openid4vc-wallet-cli
// OR
bun install -g @vidos-id/openid4vc-wallet-cli
openid4vc-wallet --help
Reference commands:
openid4vc-wallet init --wallet-dir ./wallet
openid4vc-wallet receive --wallet-dir ./wallet --offer "<openid-credential-offer://... or HTTPS offer URL>"
openid4vc-wallet present --wallet-dir ./wallet --request "<openid4vp://... authorization URL>"
Flow
- Use a stable wallet directory such as
./wallet, initialize it once withopenid4vc-wallet init --wallet-dir ./wallet, and reuse it across the full flow. - Wait for the user to share the delegation offer URL or
openid-credential-offer://link, then receive the credential withopenid4vc-wallet receive --wallet-dir ./wallet --offer "<offer>". - Browse events with
GET /api/eventsand event details withGET /api/events/:id. - Start a delegated booking with
POST /api/bookingsand body{ "eventId": "evt-001", "quantity": 2 }. - Read
authorizeUrlandstatusTokenfrom the booking response. - Present the delegated credential with
openid4vc-wallet present --wallet-dir ./wallet --request "<authorizeUrl>". - After presentation, wait a few seconds, then poll
GET /api/bookings/status/<statusToken>every 3 seconds for up to 180 seconds. - Report the final booking outcome clearly.
Booking Status
confirmed: booking succeededrejected: verification failed, reporterrorMessageexpired: verification session expirederror: reporterrorMessage
Rules
- Never ask the user for identity details that should come from the credential.
- Never skip verification or invent a successful booking.
- Never re-initialize an existing wallet unless the user explicitly asks for it.
- Use
openid4vc-walletexclusively for all credential operations. - Do not build custom OID4VCI or OID4VP implementations.
- Do not create scripts, helpers, or ad hoc code to receive, parse, sign, store, import, export, or present credentials.
- Do not manually construct protocol messages, proofs, JWTs, or credential request payloads when
openid4vc-walletsupports the flow. - Use
openid4vc-wallet receivefor delegation credential intake andopenid4vc-wallet presentfor booking authorization. - Always use the returned
authorizeUrlwithopenid4vc-wallet present. - After presentation, wait briefly, then poll booking status and report the outcome.
- Show events in concise prose or bullets, not raw JSON or markdown tables.
- When proposing events, you may pair event details with the image URL
https://eudi-usecase.demo.vidos.id/ticket-agent/event-images/<event-id>.
