Video search

Live video search: ranked video results (title, video page URL, description, duration, creator, publisher, thumbnail, age) from an independent search index as clean JSON. Send GET /api/search-videos with the required field q and pay $0.02 per call over x402 or MPP (there is no free tier). It returns a JSON object with query, count and results.

Completes the web/news/images search family. Same freshness filter (pd/pw/pm/py); strict safe-search is on by default.

Parameters

Example request

curl -i "https://agent402.tools/api/search-videos?q=agent+payments&count=5"

Without payment this returns HTTP 402 Payment Required with the exact price for search-videos; any x402 v2 or MPP client pays it and retries.

Example response

{
  "query": "agent payments",
  "count": 2,
  "results": [
    {
      "title": "The future of agentic payments",
      "url": "https://www.youtube.com/watch?v=example",
      "description": "How payment infrastructure for AI agents is built…",
      "age": "March 23, 2026",
      "duration": "14:58",
      "creator": "Example Channel",
      "publisher": "YouTube",
      "thumbnail": "https://imgs.search.brave.com/..."
    }
  ]
}

From an MCP client

catalog.call {
  "slug": "search-videos",
  "params": {
    "q": "agent payments",
    "count": 5
  }
}

The hosted connector at https://agent402.tools/mcp needs a payment for search-videos; the stdio package pays it from a wallet or from AGENT402_CREDITS_KEY. Local install: npx -y agent402-mcp.

Errors and behavior

• q is required. An input the tool rejects returns an HTTP 4xx whose body carries error, tool, expected, required and example, so the caller can correct it.
• A paid call that ends in any status of 400 or above is not charged over x402, MPP or a prepaid credits key: settlement is cancelled when the tool fails. The exception is a Tempo push credential, a transfer the buyer sent before the call: it settles before the tool runs, so if the tool then fails the payment is recorded as a refund owed to the paying wallet.
• Wallet-only: this tool reaches the network or stored state, so it has no proof-of-work tier. A prepaid card-credits key issued earlier (Authorization: Bearer a402_...) also pays it.
• A POST with a JSON body to /api/search-videos is served as this GET, with the body as the input.
• An Idempotency-Key header makes a retried paid call replay the first 200 instead of charging again (an answer larger than 1 MB is not replayed).

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls?.(false); // keep your own spending ceiling in code
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/search-videos?q=agent+payments&count=5");
