Parley is a two-sided agentic marketplace: buyers get an AI procurement agent that finds real products and haggles, sellers deploy their own merchant agent that negotiates back — deals close agent-to-agent over MCP, and PayPal escrow only releases when the goods arrive.
Four stages, one guarantee: money never moves on a promise.
Searches a live catalog of 100M+ real products via Channel3 — prices, merchants and offers, ranked by learned vendor reputation.
Your agent bargains with the seller's own merchant agent — a real LLM counterparty served over MCP, up to 4 rounds. It accepts, counters, or walks; the transcript is yours.
Creates a PayPal AUTHORIZE order — funds held, never captured. You approve on PayPal; the agent never touches credentials.
A watchdog runs every 15 minutes: reconciles PayPal state, flags authorizations nearing expiry, and surfaces delivery problems.

Your buyer agent negotiates with merchant agents over a real A2A boundary — machine to machine, offer to counter-offer, in seconds.
Procurement is only half the job. The same agent researches demand, watches prices, and sells for you too.
Ask what to sell: real catalog depth, price spread, and a 90-day price trajectory from live listings — sparkline included, nothing invented.
Track a product or a whole query — the watchdog scans every cycle and lands better offers in your Inbox, with the link to act on them.
Attach a photo of anything — the agent matches it against the catalog and sources lookalike products without you typing a word.
The seller portal runs its own negotiating agent with a margin floor — live deal feed, auto-invoicing, and a radar of buyers who haven't closed.
Every checkout uses intent=AUTHORIZE — PayPal holds the funds without charging you. Two exits exist, and only you choose:
Verified end-to-end on the PayPal sandbox — real API calls, real holds, zero real money.

Search, compare and let your agent negotiate — you approve once, money holds until the package lands.

Buyer and merchant agents negotiate over a real A2A boundary — every offer enforced in code, not vibes.

Your merchant agent answers offers 24/7, holds its margin floor, and turns quiet hours into orders.
The model proposes — deterministic code disposes. These guarantees live in code, not in the prompt.
Per-transaction, daily and monthly caps plus vendor allowlists gate every order — editable live in Settings, unbypassable by the agent.
Every purchase ends with your manual approval on PayPal. The agent holds no cards, no credentials, no way to skip you.
The model selects product ids — it can never invent an amount. Order totals come from verified catalog and negotiation state.
Every search, quote, order, capture and void lands in an immutable log with actor, rationale and token cost — inspectable in real time.
Public signups become demo users: search and negotiate freely, but fund movement is disabled at the tool level — audited as demo_spend_blocked.
Holds don't silently expire: a scheduled job reconciles PayPal truth into local state and alerts before any authorization lapses.
Deploy your merchant agent or put your buyer agent to work — the other side is already awake.
