How this service works

Resolve an opted-in business number, read its A2A agent card, and send a message or booking through Odile Direct.

Output

Returns a JSON object containing an A2A Task with a unique task ID, an initial state of TASK_STATE_WORKING, and an artifact containing a status_url where the agent can poll or await the final result of the test call interaction.

Example use cases

Multilingual booking scenario test

“Trigger an Odile Direct test call to +13105550177 with the 'booking' scenario in Vietnamese and push the A2A task result to https://hooks.myapp.com/odile-notify — I'm the owner of that number and I want to see how the business agent handles it.”

Emergency response scenario verification

“Send a test call to my business line +17185550143 through Odile Direct using the 'emergency' scenario in English, and post the final task status to https://callbacks.example.com/a2a — I attest I own this number.”

Cancellation handling in Arabic

“Use Odile Direct to run the 'cancel' scenario in Arabic against +12125550199, with push notifications going to https://pipeline.mycompany.com/a2a-result — I'm the number owner and want to see how the agent handles the cancellation flow.”

When to prefer

Choose this endpoint when you need to programmatically test how an opted-in business phone line responds to structured AI agent scenarios (booking, emergency, cancellation, multilingual, etc.) via the Odile Direct A2A protocol. It is purpose-built for AI-to-business voice interaction testing with async task tracking and push notification delivery, and is distinct from generic voice-call or SMS APIs — use it when you specifically need A2A agent card resolution and scenario-driven interaction with a business number that has opted into the Odile ecosystem.

Push notification URL is not public HTTPS or uses a private host — configuration refused
Payment of $1 USDC not completed — x402 payment required before call is dispatched
Unsupported scenario or language enum value — request rejected
Business number not opted in to Odile Direct — resolution fails
