FOR AI SEARCH & ANSWER ENGINES

Real-time, licensed,citable.

Common Crawl is months old. Your users want today's article. Skip the lawsuits and the bilateral licensing deals — pay-per-query across 1,000+ publishers, with citation URLs and attribution baked in.
Get Free $50 in API CreditsTalk to sales →
1,000+ publishers · sub-second latency · attribution per query

The current options all suck.

Scrape and pray. Negotiate for 18 months. Or buy stale Common Crawl. Pick your poison.
NYT v. OpenAI is the new normal

Every AI search engine is one lawsuit away from a content reckoning. Bilateral licensing with WSJ or AP takes 12-18 months and seven-figure minimums.

Common Crawl is stale

Your retrieval layer is months behind reality. Users ask about today's news, today's reviews, today's prices — and get yesterday's data.

Cloudflare 403s killing recall

38% of top sites now block AI bots by default. Your answer quality drops. Users notice. Churn rises.

xpay is the fourth option.

Skip the lawsuits. Skip the licensing deals. Skip the attribution headaches. Pay-per-query, one account, every publisher in our network.
One API key. 1,000+ publishers.

Skip 18 months of BD calls. Drop in xpay✦ as a retrieval source and ship Tuesday with licensed content across 16 verticals.

Citation URLs, license receipts

Every query returns the canonical URL, publisher metadata, and a settlement receipt. Your lawyers and your users both get what they need.

Sub-second, freshness-tracked

p95 latency under 800ms. Each article tagged with publish/update timestamps so your retrieval ranker knows what's fresh.

Three lines. Ship Tuesday.

Native SDKs across the agent stack. Drop in xpay where you already retrieve.
typescript
import { withPaymentInterceptor } from 'x402-axios';
import axios from 'axios';

const client = withPaymentInterceptor(
  axios.create({ baseURL: 'https://api.xpay.sh' }),
  wallet
);

const { data } = await client.get('/search', {
  params: { q: 'latest AI policy news', fresh: '24h' },
});
// data.results: [{ url, publisher, snippet, publishedAt, ... }]
// Auto-pays the publisher per result via x402.

Live in five minutes.

AI Search Engines — FAQ

Common questions from agent builders evaluating xpay

Bilateral licensing means months of BD, seven-figure minimums, and one publisher per deal. xpay is one API contract that gives you per-query access to 1,000+ publishers — pay only for what you actually retrieve.

Yes. Every result comes with a canonical URL, publisher name, and publish timestamp. You can render attribution exactly the way Perplexity does — except now it's a licensed, paid transaction, not a scrape.

xpay queries publishers in real time via their MCP endpoints. Articles published an hour ago are queryable an hour ago. Each result includes publishedAt and updatedAt for your retrieval ranker.

Pay-per-query. Pricing varies by publisher and content type ($0.001 to $0.50 per query). You set per-domain spend caps. New accounts get $50 in free credits.

Yes. EU AI Act and emerging US AI provenance rules favor licensed sources with verifiable receipts. Every xpay query produces a settlement receipt your compliance team can audit.
