## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability zeroclick-affiliate-com-zeroclick-agent-api-quote-purchase-guide-144c4312 -d '<json body>'
```

Example prompt: Can you get me a free quote for using the ZeroClick affiliate product search API to look up merchant product listings — my goal is to search for electronics products across all merchants, I expect around 500 API calls, and my total budget is $20?

## When to prefer this

Use this endpoint when an agent or user wants to discover what API contract, pricing, and prerequisites apply to a specific task before committing any spend or setting up payment credentials. It is the right choice for pre-purchase planning, budget validation, wallet-free environments, or when onboarding a new autonomous agent that needs to understand costs and steps before acting. Prefer this over the paid service endpoints when no wallet is available or when the user explicitly wants a dry-run cost estimate.

## Known failure modes

- Missing required 'goal' field returns a validation error
- Goal description too long (>2000 chars) is rejected
- Invalid payment enum value causes schema validation failure
- Quantity or budget values outside allowed ranges are rejected
- Status may return 'unsupported' or 'unavailable' if the described task has no matching API
- Status 'needs_input' indicates more detail is required in the goal description
- Status 'blocked' may indicate the task cannot be fulfilled at all

## How this service works

Product catalog search across all Affiliate.com merchants. Search and retrieve products with structured queries, and look up the merchants behind the catalog. This server is a pay-per-use, transparent proxy in front of Affiliate.com's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.

## Output

A JSON object with a status field (e.g. 'quoted', 'ready', 'needs_input'), a priceUsd field always set to '0' (this lookup is always free), a markdown 'guide' field with the matched API contract details, exact pricing, prerequisites, and next steps, and a 'guideUrl' pointing to a wallet-free advisor endpoint for follow-up.
