# Prysm YDC Search Provider

> Prysm YDC Search Provider is a paid API for AI agents from prysm-kappa.vercel.app, paid per call via x402, $0.12/call, status unknown (last checked 2026-10-21).

Proxies search operations to the You.com (YDC) search API via Prysm's x402-gated endpoint, returning web search results payable in USDC on Base.

## 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 prysm-ydc-search-provider-56c2d7e9 -d '<json body>'
```

Example prompt: Search for the latest news about Ethereum Layer 2 scaling solutions using the YDC provider on Prysm and return the top results.

## When to prefer this

Choose this endpoint when your agent needs live web search results and is operating in an x402-compatible payment environment on Base mainnet with USDC. It is particularly useful when you need access to You.com's search index and want a simple, pay-per-call model without managing API keys directly. Prefer this over free-tier search APIs when freshness and reliability matter, or when integrating into an autonomous agent that can handle microtransactions natively.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not processed correctly
- Invalid operation: operation string not on the allowlist for the YDC provider
- Malformed input: missing or incorrect fields in the input object
- YDC upstream error: You.com API is unavailable or rate-limited
- Empty results: query returns no matching documents

## How this service works

Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.

## Output

A JSON object containing a 'data' field with the raw search results from the YDC provider, a 'provider' field set to 'ydc', and an 'operation' field indicating the operation performed (e.g. 'search'). The data field contains provider-specific search result structures including titles, URLs, and snippets.
