--- title: "Commerce Evidence for AI-Driven Commerce | DubbleBlack" url: https://www.dubbleblack.com/ fetched_at: 2026-10-10T23:53:30.880Z --- # DubbleBlack API catalog and pricing ## API reference, endpoint lookup and prices **[DubbleBlack API catalog: endpoints, request parameters, prices and payment methods](https://agents.dubbleblack.com/zcj/hrgrusa7wucd/zeroclick/agent/guide).** Tell the seller advisor what you want to accomplish. 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: Powder Evidence. **Suggested next request:** GET [task guide](https://agents.dubbleblack.com/zcj/hrgrusa7wucd/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.dubbleblack.com/zcj/hrgrusa7wucd/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.dubbleblack.com/zcj/hrgrusa7wucd/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. Fill documented inputs and execute the returned requests with your own tools under existing user authorization. Check usage cost AND minimum cash required against the budget. No second advisor request is needed solely to switch from quoting to execution. For needs_input, supply only missing facts. Check configured credential storage and payment tools when needed; reuse existing identity and access, 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, with authorized email disclosure. An empty or expired Link credential list means request a credential, not fall back to anonymous. Follow [Link identity setup](https://agents.dubbleblack.com/zcj/hrgrusa7wucd/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.dubbleblack.com/zcj/hrgrusa7wucd/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.dubbleblack.com/zcj/hrgrusa7wucd/SKILL.md) or [full direct workflow reference](https://agents.dubbleblack.com/zcj/hrgrusa7wucd/llms-full.txt). Confirm missing request details from seller documentation, stay within the existing catalog and user authorization, 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`. # Commerce Evidence Built from Real Commerce Activity DubbleBlack creates, gathers, and connects commerce evidence so AI agents and enterprises can make better commerce decisions. [Talk to DubbleBlack](https://www.dubbleblack.com/contact) | [Explore Powder](https://www.dubbleblack.com/powder) AI-driven commerce requires trustworthy evidence. DubbleBlack creates and gathers that evidence from commerce pilots, proprietary vertical networks, external sources, AI recommendation research, consumer intent, and verified commerce outcomes. Powder is the Commerce Evidence Layer. It connects and evaluates those signals to produce recommendation evidence for AI agents and commerce intelligence for enterprise buyers. --- ## Powder Evidence: Pay-as-You-Go Powder Evidence is a digital commerce-evidence service available pay-as-you-go for **$0.10 USD per evidence request** through ZeroClick/x402. No subscription or prepaid plan is required. ### Optional Prepaid Credits Prepaid Credits are optional, non-recurring funding. They are not a subscription and not a prerequisite for pay-as-you-go access. Purchasing Credits requires a ZeroClick agent identity and bearer token. Anonymous agent identity creation requires no human step. Claiming an identity to a verified email is a separate, optional workflow. The current minimum new card-funded Credits purchase is **$0.50**. [Powder integration guide](https://data.dubbleblack.com/integration-guide) --- ## The Platform DubbleBlack operates four evidence systems that accumulate into Powder. - **Snowgun** creates evidence through commerce pilots. - **Snowcat** owns proprietary evidence from vertical networks. - **Snowplow** gathers external evidence. - **Snow Report** observes AI recommendation behavior. ### Snowcat DubbleBlack's vertical networks generate proprietary behavioral and transaction evidence across focused commerce categories. [View Snowcat Networks](https://www.dubbleblack.com/networks) ### Snowplow Snowplow expands Powder's coverage by gathering external product, publisher, intent, and commerce evidence from source-agnostic external services. [Learn About Snowplow](https://www.dubbleblack.com/snowplow) ### Powder Powder is the Commerce Evidence Layer. It connects consumer intent, recommendation behavior, product data, and verified commerce outcomes. [Explore Powder](https://www.dubbleblack.com/powder) ### Snowgun Commerce pilots create fresh commerce evidence through brand campaigns, media programs, clicks, conversions, and purchase behavior. [Explore Snowgun](https://www.dubbleblack.com/snowgun) --- ## Snow Report: Where Did That Recommendation Come From? Snow Report examines how AI platforms recommend products and which sources shape those answers. Snow Intelligence turns that research into enterprise monitoring and structured commerce intelligence inside Powder. [Explore Snow Report](https://www.dubbleblack.com/snow-report) | [Explore Snow Intelligence](https://www.dubbleblack.com/powder/snow-intelligence) **Latest Report:** [Snow Report: Dog Food](https://www.dubbleblack.com/snow-report/dog-food) — Research in progress Coming soon: Pet Wellness, Protein, Skincare, Supplements --- ## Why Commerce Evidence AI shopping is changing product discovery. The old commerce data stack was built around search, cookies, last-click attribution, and platform reporting. None of that captures what shoppers actually asked, what alternatives they considered, or why they came back to buy again. AI platforms need something different: structured, verified signals from real discovery conversations, real recommendations, and real transactions. Scraped catalog data and modeled intent cannot provide that. DubbleBlack builds commerce evidence infrastructure for AI-driven commerce. Powder connects the evidence and evaluates it against specific consumer intent. --- ## The Architecture Four independent evidence systems accumulate into Powder. Powder then distributes the evidence through the channel built for the decision. | System | Role | |---|---| | Snowcat | Owns proprietary evidence | | Snowgun | Creates pilot evidence | | Snowplow | Gathers external evidence | | Snow Report | Observes recommendation behavior | | **Powder** | Connects and evaluates accumulated evidence against specific commerce intent | **For Agents — ZeroClick:** Recommendation evidence distributed to AI agents at the moment of decision. **For Enterprises — FirstParty:** Commerce intelligence packaged and distributed to enterprise buyers. --- ## Case Study: An AI Agent Paid Powder for Commerce Evidence ZeroClick documents three different test outcomes: evidence supported a choice, was insufficient to change it, or changed it. ZeroClick also reproduced a separate paid evidence request. [Read the ZeroClick Case Study](https://zeroclick.ai/blog/how-dubbleblack-sells-commerce-evidence-to-ai-agents) --- ## Who We Serve **AI Agents** — Need trusted commerce evidence at the moment they decide which product or brand to recommend.
