# AgentFeed Web Search

> AgentFeed Web Search is a paid API for AI agents from agentfeed.up.railway.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Performs a paid web search query and returns ranked results with titles, URLs, descriptions, and age, gated by x402 micropayment.

## 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 agentfeed-web-search-c5bb5c39 -d '<json body>'
```

Example prompt: Search the web for the latest developments in quantum computing from the past week and give me the top 5 results with their titles and descriptions.

## When to prefer this

Choose this endpoint when an AI agent needs to retrieve current or recent web information with metadata (title, URL, description, age) and can handle micropayment via x402. Particularly useful for time-sensitive queries where freshness filtering (past day/week/month/year) is important. Prefer over free alternatives when reliability and freshness filtering matter, and the $0.02 per-call cost is acceptable.

## Known failure modes

- Empty or missing query field returns a validation error
- Freshness value outside allowed options (past day/week/month/year) may be rejected or ignored
- Payment failure via x402 results in HTTP 402 and no results returned
- Very niche or rare queries may return zero results
- Count parameter exceeding service limits may be capped silently

## How this service works

Six payment-gated endpoints for AI agents: content extraction, price oracle, URL unfurling, web search, RSS parsing, and translation.

## Output

Returns a JSON object containing the original query string, the count of results returned, and an array of result objects each with a URL, title, short description, and age indicator (e.g. '2 days ago'). Costs $0.02 USDC per call via x402 payment.
