How it works

How AI agents buy — and how Conduit makes it work

Agentic commerce replaces the human checkout loop with a single API call. An agent describes what it needs, Conduit searches every connected merchant at once, ranks the results on price, execution-readiness, and reputation, and the agent completes or hands off a real checkout — in minutes, with no captchas, manual sign-up, or hand-entered cards.

Here is the end-to-end flow, from identity to delivery.

  1. 01

    One identity

    An agent registers a keypair and re-authenticates by signing a challenge — no forms, no shared secret. That single identity becomes every protocol handshake (UCP, ACP, AP2, x402).

  2. 02

    Set a mandate (optional)

    A human approves spend limits, categories, and expiry via AP2 to unlock fully autonomous payment. Skip it and discovery plus human-approved handoff still work.

  3. 03

    Search supply

    One query searches thousands of merchants at once, filtered to rails the agent can actually pay, and ranked on the merits — price, execution-readiness, reliability, and reputation.

  4. 04

    Decide on real signal

    Every offer carries stated-vs-observed delivery, on-time rate, per-carrier reliability, Agentic Execution Score, and product and merchant ratings — so the agent avoids offers it cannot complete.

  5. 05

    Execute or hand off

    The agent completes checkout autonomously on a rail it holds, or hands off a ready continue_url for a human to finish in one step. Money flows straight to the merchant and never through Conduit.

  6. 06

    Track and settle reputation

    Live tracking with stated-vs-observed ETAs lands in one command center, and reported outcomes feed two-sided reputation and AES — so good suppliers and reliable agents compound over time.

Frequently asked questions

How can AI agents buy physical goods?
An AI agent buys physical goods by calling a commerce interface that exposes live inventory, prices, payable rails, and checkout. Conduit gives agents one neutral MCP/REST endpoint to search thousands of merchants at once, compare offers on execution-readiness and reputation, and complete or hand off checkout — without browsing human-first storefronts, captchas, or manual card entry.
What is agentic commerce?
Agentic commerce is software agents discovering, negotiating, and purchasing goods and services autonomously on a person or company’s behalf, instead of a human clicking through a website. It runs on emerging open protocols like UCP, ACP, AP2, x402, and MCP.
How do I let an AI agent purchase on my behalf?
You give the agent a keypair identity and a spend mandate — limits, categories, and expiry it must stay within, for example via AP2. The agent then discovers supply, picks the best offer, and either completes an autonomous checkout on a rail it holds or hands off a ready cart for you to approve. Conduit translates one agent keypair into the handshake each merchant trusts.
How do AI agents pay merchants?
Agents pay on rails they can hold — cards, Stripe Link, stablecoins, or x402 web-native crypto payments — within a human-approved mandate. Conduit routes each order to a rail the merchant accepts and the agent holds; money flows straight from the buyer instrument to the merchant and never through Conduit.
How is agentic commerce different from traditional online checkout?
Traditional checkout assumes a human: a browser, a cart, manual card entry, captchas, and 3D-Secure. Agentic commerce is API- and protocol-native — an agent discovers normalized supply, decides on price, reliability, and execution-readiness, and completes or hands off checkout in seconds, with no human in the loop unless one is wanted.
What happens if an agent cannot complete a checkout autonomously?
Conduit hands off a ready cart via a real continue_url so a human can finish in one step, and the offer’s Agentic Execution Score flags that risk up front. Agents can prefer offers they can actually complete on a rail they hold, rather than hitting a human wall at the end.
