Install Jentic One Beta

Connect the Authorized Buyers Marketplace API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Authorized Buyers Marketplace API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fgoogleapis.com%2Fauthorizedbuyersmarketplace" | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fgoogleapis.com%2Fauthorizedbuyersmarketplace" | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Use Cases

Patterns agents use Authorized Buyers Marketplace API for, with concrete tasks.

★ Programmatic Direct Deal Negotiation

Initiate, negotiate, and finalise private deals with publishers programmatically rather than by manual UI flows. The API supports sending an RFP, listing the publisher's response, patching deal terms, and ultimately marking the deal ready to serve. Suitable for trading desks that manage hundreds of deals and want them version-controlled in code.

POST an RFP payload to /v1/{buyer}/proposals:sendRfp with target inventory, dates, and price, then poll the proposal until the publisher responds.

Auction Package Subscription Management for Agencies

Manage which client accounts under an agency buyer have access to which curated auction packages. The API supports listing available packages, subscribing a set of clients to a package, and unsubscribing them when the campaign ends. Keeps client access tightly scoped without manual provisioning.

POST a list of client resource names to /v1/{auctionPackage}:subscribeClients to grant them access to that package.

Creative Trafficking and Deal Activation

Attach approved creatives to a finalised deal and then mark the deal ready to serve so it begins receiving impressions. The API exposes addCreative and setReadyToServe as discrete operations so trafficking and activation can be tracked and audited in a workflow tool.

POST the creative resource name to /v1/{deal}:addCreative, then POST to /v1/{deal}:setReadyToServe to activate.

AI Agent for Deal Hygiene via Jentic

Use an AI agent to keep a buyer's pipeline clean by listing open proposals, flagging stalled negotiations, and following up with publishers via standardised RFP messages. Through Jentic the agent searches by intent, loads each operation's schema, and executes calls without managing OAuth refresh logic itself.

Use Jentic search for 'list authorized buyers proposals', filter results by lastUpdatedTime older than 14 days, and call sendRfp to nudge stalled deals.

Key Endpoints

27 endpoints — the authorized buyers marketplace api lets authorized programmatic buyers discover publisher inventory, propose private deals, negotiate terms, and manage finalised deals at scale.

Why Jentic?

What agents get from Jentic-routed access to this vendor.

Setup

Wiring the Authorized Buyers Marketplace API by hand means setting up Google OAuth2, scoping the buyer account, and refreshing access tokens for each proposal and deal call yourself. Through Jentic you install once, import the Authorized Buyers Marketplace API from the API Directory, store the OAuth credential once, and your agent calls it.

Permission scoping

This API puts the buyer, deal, and auction package in the URL path (/v1/{buyer}/proposals:sendRfp, /v1/{deal}:addCreative), so a rule can pin your agent to one buyer: it can send RFPs, add creatives, and subscribe clients for that buyer and nothing else. You choose the operations it may call, so actions like setting a deal ready to serve are not included unless you add them.

Credential isolation

Your Authorized Buyers OAuth credential is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'send an RFP to a publisher' or 'add a creative to a deal', and Jentic returns the matching Marketplace operation with its input schema so the agent calls the right endpoint without navigating the Authorized Buyers reference.

FAQs

Specific to using Authorized Buyers Marketplace API through Jentic.

What authentication does the Authorized Buyers Marketplace API use?

The API uses Google OAuth 2.0 with the authorized-buyers-marketplace scope. The OAuth client must be linked to an Authorized Buyers buyer account approved by Google. Through Jentic the OAuth credential is held in the encrypted vault and only short-lived access tokens reach the agent.

Can I send RFPs to publishers through this API?

Yes. POST to /v1/{buyer}/proposals:sendRfp with the publisher reference, target inventory, flight dates, and pricing terms. The publisher then responds asynchronously and the proposal can be polled and patched until both sides agree.

How do I attach a creative to a deal through Jentic?

Search Jentic for 'attach a creative to an Authorized Buyers deal'. Jentic returns the POST /v1/{deal}:addCreative operation with its schema; execute it with the deal name and creative resource name, then follow with setReadyToServe to activate.

What are the rate limits for the Authorized Buyers Marketplace API?

Numeric limits are not declared in the OpenAPI spec; quotas are enforced per Google Cloud project on authorizedbuyersmarketplace.googleapis.com. Check the project quota dashboard before scheduling large list jobs across many buyer accounts.

Does this API report on impressions or revenue?

No. This API covers deal negotiation, client subscriptions, and creative attachment only. Impression-level reporting lives in the Ad Manager API and the Authorized Buyers Real-Time Bidding APIs.

Can I subscribe multiple agency clients to the same auction package?

Yes. POST /v1/{auctionPackage}:subscribeClients accepts a list of client resource names so an agency can grant access to many clients in a single call.

Can I limit what my agent is allowed to do with the Authorized Buyers Marketplace API?

Yes. Because you run Jentic One yourself, your own rules decide which operations and credentials the agent may use, and this API puts the buyer, deal, and auction package right in the URL path (/v1/{buyer}/proposals:sendRfp, /v1/{deal}:addCreative), so you can pin the agent to a single buyer account. You choose the exact operations it may call, for example letting it send RFPs, add creatives, and subscribe clients while omitting setReadyToServe so it can never mark a deal live on its own. The Google OAuth credential stays with your instance and is injected only when an allowed call runs, so the agent acts only within the scope you granted.

For Agents

Discover programmatic ad inventory, propose and negotiate private deals with publishers, and attach creatives in Google Authorized Buyers Marketplace.

Use for: I need to send an RFP to a publisher for a Q3 video deal, List all open proposals for my buyer account, Attach a creative to a deal before turning it on, Mark a deal as ready to serve once trafficking is complete

Not supported: Does not deliver impressions, run real-time bidding, or report on served traffic - use for proposal, deal, client, and auction-package management in Authorized Buyers only.

The Authorized Buyers Marketplace API lets authorized programmatic buyers discover publisher inventory, propose private deals, negotiate terms, and manage finalised deals at scale. It exposes operations to send RFPs to publishers, subscribe clients to auction packages, attach creatives to deals, and signal that a deal is ready to serve. Resources are scoped to a buyer account and the API is the integration surface between a DSP or trading desk and Google's Authorized Buyers programmatic marketplace. It does not deliver impressions or report on served traffic.
