How this service works
Merge many RSS, Atom and JSON feeds into one typed, deduplicated stream. This server is a pay-per-use, transparent proxy in front of Feed's own API: call the upstream API's paths here and the proxy handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. No seller API operations have been verified for this document; consult the upstream API reference. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits). See the upstream API's own OpenAPI document at https://feed.withzero.xyz/openapi.json for the available operations and schemas, and call those paths through this server.
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.
Example use cases
Pre-purchase cost check for feed merger
“I want to know how much it'll cost to merge 200 RSS feeds into one stream using the ZeroClick feed API — can you get me a quote without spending anything? I'll be using x402 payment and have a $10 budget.”
Autonomous agent API planning
“My bot needs to aggregate 10 JSON feeds per hour without any human approval. Can you look up the API contract and prerequisites so I can plan the integration — no wallet needed for this lookup, and flag that there's no human in the loop.”
Exploring feed deduplication options
“I'm not sure how many API calls I'll need yet, but I want to understand what's involved in deduplicating Atom and RSS feeds through this proxy — can you pull the free guide and show me the pricing and next steps?”

Endpoint

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.
Side effects
- 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
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| goal | string | Describe the task and known inputs. Do not include credentials. |
| payment | string | Known payment method for the eventual purchase, independent of this free lookup's wallet proof. |
| quantity | integer | Number of API calls, not returned items. Omit when unknown; describe desired output in goal. |
| budgetUsd | string | Total cash budget in USD. A quote does not authorize spending. |
| requirements | string | |
| humanAvailable | boolean | Whether a human is in the loop. False recommends anonymous auth for a new autonomous identity; omit when unknown. Executing a human's request without further interruptions does not by itself mean false. |
| budgetExclusive | boolean | |
| reviewAfterCalls | integer |
