> Odile Direct: AI-to-Business Messaging & Booking is a paid API for AI agents from api.odilelabs.com, paid per call via x402, $2/call, status unknown (last checked 2026-10-31).

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability odile-direct-ai-to-business-messaging-booking-44fdea9e -d '<json body>'
```

Example prompt: Contact the business at the opted-in number for Morning Bloom Coffee and ask them if they have availability for a private event for 20 people next Saturday afternoon — also mention we'd need setup by 10am.

## When to prefer this

Use this endpoint when you need to programmatically reach a business that has opted into AI-to-AI communication via Odile Direct, especially for booking requests or structured inquiries where a human phone call or email would otherwise be required. Prefer this over generic messaging APIs when the target business is registered in the Odile Direct network and you need a verifiable, on-chain settled interaction with a structured response.

## Known failure modes

- Business number not opted in to Odile Direct — no A2A agent card found
- Task string too short (under 10 chars) or too long (over 4000 chars) — validation error
- Context field exceeds 8000 character limit
- Payment of $2 USDC not settled — 402 Payment Required response
- Business agent card unresponsive or unreachable at time of call
- Malformed JSON body — missing required task field
