## What the agent for White Swan Inn looks at

In the merchant's own guidance. Share only what your user is comfortable with; nothing here promises a discount.

- Identify the service, plan or product being considered.
- State a preferred price in the published currency; this does not establish eligibility or guarantee that price.
- Explain the practical requirements that make an offer useful.
- Relevant previous purchases may help explain preferences or repeat demand; no particular discount is promised.
- Describe expected use with quantities and time period when known.
- Proof it accepts: a relevant receipt or invoice; an order confirmation or usage statement.

## For your agent

1. Open a negotiation with the traveler's haggl ID: `GET https://www.haggl.ai/api/negotiate?vendor=white-swan-inn-sf` with the `Haggl-Id` header. Cashback is paid to it; create one with their consent first (`POST https://www.haggl.ai/api/discounts/id`).
2. Ask for the rate: POST to the returned `session.negotiate_url` with `ask` (dates, room) and `data`. Signed flight or hotel emails of their trips to San Francisco in the last 12 months, in `data.proofs[].raw_mime_b64`, raise the rate. Send your haggl.ai referral code as `via`.
3. Accept with approval: POST to `session.accept_url` with `expected_offer_version`. The answer has the reference code, the booking link and the claim steps.
- Over MCP: `haggl_start_negotiation` with `vendor_id` `"white-swan-inn-sf"` on `https://www.haggl.ai/api/mcp`. The full flow is in the agentic discounts skill: https://www.haggl.ai/agentic-discounts/SKILL.md
