Why agent-tools.net

For agents & developers<br>Integrate in one request

No signup flow to script around. Your agent hits an endpoint, reads the price<br>off the 402 response, signs, and retries. The whole loop fits in a single<br>function.

For tool builders<br>Distribution without a billing system

List your own agent-facing tool for $2/30 days, paid the same way you sell<br>calls — no Stripe, no accounts, no invoices. Show up in the directory other<br>agents actually search.

How a call actually works

01<br>Request normally.<br>GET /extract?url=... — no header, no key, nothing to configure up front.

02<br>Get a 402.<br>The PAYMENT-REQUIRED header carries the exact price, network (Base), asset (USDC), and address — machine-readable.

03<br>Sign and retry.<br>Your agent signs an EIP-3009 authorization for that amount and resends with X-PAYMENT. Verified, settled, and answered in one round trip.

Our own departures

Four endpoints we run ourselves — also listed in the directory below, same as anyone else's.

GET /extract · $0.005<br>/extract

Fetch a URL server-side and return clean {title, text, links} extracted from its HTML — skip the HTML parsing.

curl "https://agent-tools.net/extract?url=https://example.com" \<br>-H "X-PAYMENT: "

GET /scrape · $0.01<br>/scrape

Structured scraping with simple selectors (tag, tag.class, tag#id) — repeat &field= for multiple columns, zipped into rows by document order.

curl "https://agent-tools.net/scrape?url=https://example.com&field=title=h2.product-title&field=price=span.price" \<br>-H "X-PAYMENT: "

GET /status · $0.001<br>/status

Is this URL up? Status code, final redirect target, response time, content-type — without downloading the page body.

curl "https://agent-tools.net/status?url=https://example.com" \<br>-H "X-PAYMENT: "

GET /robots-check · $0.001<br>/robots-check

Will this URL let you fetch it? Checks robots.txt for a given (or your own) user-agent before you spend a call finding out the hard way.

curl "https://agent-tools.net/robots-check?url=https://example.com" \<br>-H "X-PAYMENT: "
