Give your AI agent live web search for $0.003 a query, no API key

Your agent can't Google. Every "research agent" tutorial hand-waves this step: you go get a search API key, put it in an env file, set up billing, and hope the key never leaks out of a prompt.

There is a simpler way now that x402 exists: the agent pays for each query itself, from its own wallet, in USDC on Base. No signup, no key, no plan. Here is the whole integration.

curl -H "X-Free-Trial: 1" \ "https://search.cyberwarex.com/search?q=x402+payment+protocol&n=3" Enter fullscreen mode Exit fullscreen mode You get back plain JSON: title, url, snippet, source engine. Three free calls a day per IP, no account.

pip install x402 eth - account from x402.clients.requests import x402_requests from eth_account import Account s = x402_requests ( Account. from_key ( PK )) # a wallet with a little USDC on Base r = s. get ( " https://search.cyberwarex.com/search ", params = { " q ": " latest base chain news ", " n ": 5 }). json () for hit in r [ " results " ]: print ( hit [ " title " ], hit [ " url " ]) Enter fullscreen mode Exit fullscreen mode TypeScript:

npm i x402 - fetch viem import { wrapFetchWithPayment } from " x402-fetch "; import { privateKeyToAccount } from " viem/accounts "; const f = wrapFetchWithPayment ( fetch, privateKeyToAccount ( PK )); const r = await f ( " https://search.cyberwarex.com/search?q=latest+base+chain+news&n=5 " ); const { results } = await r. json (); Enter fullscreen mode Exit fullscreen mode What happens under the hood: the first request gets an HTTP 402 with a price quote ($0.003 = 3000 micro-USDC), the client signs an EIP-3009 authorization, retries with an X-PAYMENT header, and the server settles it through the Coinbase facilitator. Gasless for the payer. Queries that return zero results are not charged.

/search-contents is the one I would start with for a research agent: it collapses the search-then-fetch loop into one paid call.

r = s. get ( " https://safe.cyberwarex.com/subscribe?usd=3 " ). json () # $3 -> $3.30 credit -> 1,100 searches requests. get ( " https://search.cyberwarex.com/search ", params = { " q ": q }, headers = { " X-Subscription-Key ": r [ " key " ]}) Enter fullscreen mode Exit fullscreen mode Why not just a free search API Free tiers are shared resources with per-IP limits and surprise deprecations. A key is a secret your agent has to carry. Here the wallet is the credential, the price is $0.003 (typical x402 web search is $0.01), and the results are Google-grade. Uptime and probes are public on x402-list.com.
