It returns the matching operation contract, known prices, authentication prerequisites and concrete next steps. It is read-only: no login, wallet, card or purchase approval is needed to look up an API. It never executes a sale. Available API services: Agent readiness report, Demo booking. **Suggested next request:** GET [task guide](https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/zeroclick/agent/guide?goal=URL_ENCODED_TASK). Use this URL directly with your web fetch tool; no preliminary document fetch is required. Include known inputs and desired output in the goal. Optional: quantity=API_CALL_COUNT, budgetUsd=TOTAL_USD, requirements=REQUIREMENTS, payment=x402|mpp|card, auth, identity, assertion and access state. Omit unknowns. Do not equate output items with API calls or guess a call count. For private task details or known request arguments, POST https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/zeroclick/agent/guide with Content-Type: application/json. Example: {"intent":"quote","goal":"YOUR_TASK","purchase":{"budgetUsd":"5.00"}}. Replace the task and budget with known facts; budgetUsd is a string. Include known buyerState, paymentCapabilities and arguments. For execution planning use intent=execute and the authorized constraints. Exact fields: [request schema](https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/zeroclick/agent/schema). GET and POST are alternatives, not mandatory stages. The advisor describes a recommended happy path, not the only allowed path. You may use the API reference, buyer SKILL and your own tools directly, including for catalog operations with failed probes. Missing guidance or an unverified probe is not a policy refusal. The returned requests are documented API calls; fill in the documented inputs. Check usage cost AND minimum cash required against the budget. For needs_input, supply only missing facts. Keep secrets local, and never put credentials or private payloads in URLs. Unknown does not mean absent. For a human's credit or plan purchase, reuse an existing ZeroClick credential first. Otherwise use their signed-in Link account for identity as well as payment, sharing their email only if they agree. An empty or expired Link credential list means request a credential, not fall back to anonymous. Follow [Link identity setup](https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/auth.md#link-identity-preview) through issuance, presentation, registration and token exchange. Anonymous auth remains available for agents acting on their own behalf with no human in the loop. Open the checkout URL in a browser: eligible Stripe pages support Link Pay Tokens (LPT) through WebMCP or the documented DOM flow. Follow this storefront's /payment/card.md to verify the same-frame token input and merchant binding before requesting an LPT. Token submission requires payment authorization. If unavailable, privately send the checkout URL to your human to pay. When the selected route uses hosted checkout, follow [card checkout instructions](https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/payment/card.md) before requesting a token. LPT goes only to Stripe, never to the advisor or ZeroClick API. Poll the returned statusUrl before using credit or retrying delivery. Verify delivery; a payment or HTTP 202 is not completion. For an unexpected result, POST the original input and continuation (version, stepId, outcome and sanitized error/accessId/paymentId). Reconcile uncertain payments or writes before retrying. Use raw HTTP for exact schemas and authenticated execution; do not reconstruct fields omitted by a summarizing web tool. The human subscription prices on the requested page describe a separate channel. Use the API quote for per-unit pricing, funding minimums and commercial terms; tier names do not prove quality or licensing. For an alternative documented path, use the [buyer SKILL](https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/SKILL.md) or [full direct workflow reference](https://agents.zeroclick.ai/zcj/ybnn2wd2dec2/llms-full.txt). Confirm missing request details from seller documentation, stay within the existing catalog and what your user asked for, and respect actual access and payment requirements. Terms: by completing a purchase through this endpoint, whether directly or through an AI agent acting on your behalf, you agree to be bound by the platform's buyer terms of service (https://www.zeroclick.ai/legal/buyer-terms-of-service). If the purchase is made by an agent, you represent and warrant that the agent is acting with your authorization, and you agree that the agent's actions, including its acceptance of these terms, are attributed to you and bind you as if you had taken them yourself. Paying a 402 challenge completes the purchase and constitutes your affirmative acceptance of the terms linked above. The link travels in every payment challenge and receipt as `terms`. # ZeroClick Acquires Sleek to Bring AI to the Browser [ZeroClick Team](https://x.com/zeroclick) · September 2, 2025 · 2 min read ZeroClick acquired Sleek, bringing expertise in browser automation, product data, and checkout to the team. The Y Combinator-backed company built browser shopping tools used by millions of people. ## Experience Built in the Browser Sleek built software that could navigate shopping sites, fill forms, apply coupons, and complete checkouts. Its machine learning models classified pages and processed product data in real time, helping software understand what was on a page and what to do next. At the time of the acquisition, Sleek's platform supported 10,000+ merchants and powered shopping experiences for partners including Super.com, TopCashback, and ShopBack. Founders Adam MacEachern, Daniel Baum, Palmer McCutcheon, and their team joined ZeroClick with that experience. That work addressed a practical challenge in commerce: helping software carry a purchase through to completion. Product information, forms, and checkout flows all need to be understandable and usable for software to act on someone's behalf. ## Helping Businesses Sell to AI Agents Today, ZeroClick helps businesses sell APIs, data, and digital services directly to AI agents. An Agent Storefront gives an agent a place to discover an offering, understand its price, pay, and use it. Businesses connect their existing API and choose what to sell and how to price it. ZeroClick provides: - A machine-readable storefront with a catalog, prices, and instructions agents can follow - Payments through x402, MPP, or cards, with revenue settling to the business's connected Stripe account - Agent identity and access to services sold per request, through credits, or by subscription - Analytics to see which agents visit, what they buy, and how they use a service The business continues to deliver its product through its own API. ZeroClick handles the storefront and payment flow so an agent can become a customer and get the work done. Sleek brought experience making software act in the browser. At ZeroClick, we're building for businesses whose next customer is an AI agent, with a clear path from finding a product to paying for and using it. Ready to sell to AI agents?
