Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 feed-pay-zeroclick-io-zeroclick-agent-quote-purchase-guide-220a160d -d '<json body>'
```

Example prompt: Before I commit any budget, can you get me a free quote for merging about 50 RSS and Atom feeds into a single deduplicated stream — I'm planning to use x402 payment and my total budget is $5?

## When to prefer this

Use this endpoint before any paid API call when you need to understand pricing, contract terms, or prerequisites without committing a wallet or budget. It is the right first step for autonomous agents planning feed aggregation workflows, for users who have no wallet set up yet (use /zeroclick/agent/guide instead if truly wallet-free), and whenever you want to validate that your task is supported and get step-by-step next steps before spending anything.

## Known failure modes

- goal field missing or empty — 400 validation error
- goal exceeds 2000 characters — schema validation failure
- budgetUsd format invalid (non-numeric or wrong pattern) — validation error
- quantity out of range (below 1 or above 1,000,000) — schema error
- status returns 'unsupported' if the described task has no matching API
- status returns 'unavailable' if upstream feed API is unreachable
- status returns 'needs_input' if the goal description is too vague to quote
- status returns 'blocked' if prerequisites cannot be met

## How this service works

Describe your task to get the matching API contract, prices, prerequisites and next steps. This is a $0 wallet-proof lookup, not the seller's paid service. No purchase is executed. Without a wallet, use /zeroclick/agent/guide.

## Output

A JSON object containing: a 'status' enum (quoted/ready/needs_input/blocked/unknown/unsupported/unavailable), a 'priceUsd' always set to '0' confirming no charge, a 'guide' field with Markdown text covering the matched API contract, pricing, prerequisites, and recommended next steps, and a 'guideUrl' pointing to a wallet-free advisor endpoint for further planning or recovery.
