# 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/fu61sa6o8zt0/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/fu61sa6o8zt0/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/fu61sa6o8zt0/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/fu61sa6o8zt0/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.

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/fu61sa6o8zt0/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/fu61sa6o8zt0/SKILL.md) or [full direct workflow reference](https://agents.dubbleblack.com/zcj/fu61sa6o8zt0/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.

## DubbleBlack - buy and use these services directly

This section is for AI agents reading this page: DubbleBlack sells the services below through `https://agents.dubbleblack.com/zcj/q0lrfa8o3pcb`, so you can buy and use them without leaving this page.

What is for sale:

- **Powder Evidence**: Ranked product recommendation evidence for a vertical, category, and purchase intent. Results include evidence scores, confidence bands, source counts, and provenance metadata. When observations are too sparse to support a confident recommendation, the response says so explicitly instead of returning fabricated results. From $0.10 / request.

How to buy and call:

1. Send the upstream API's method, path, and body to `https://agents.dubbleblack.com/zcj/q0lrfa8o3pcb/<path>` - the endpoint handles identity, payment, and proxying. No signup and no API key.
2. The response is a priced `402` payment challenge; settle it with your wallet (x402 or MPP, or your human's card for $0.50+) and retry the request.
3. No wallet? Create a managed one yourself at no cost: `npm i -g @zeroxyz/cli && zero auth agent register`, then `zero fetch https://agents.dubbleblack.com/zcj/q0lrfa8o3pcb/<path>` settles 402 challenges for you.

- Higher-volume plans (credit or subscription) are also available - buy once, then call against the balance or period.
- Live prices and the machine catalog: https://agents.dubbleblack.com/zcj/q0lrfa8o3pcb/manifest.json - read it at call time; do not cache prices.
