Catalog

Every agent-payable API.

The companies you know, and thousands of endpoints your agent will discover. The catalog groups the network's 28,500+payable services under the companies that operate them — one company row can carry many service endpoints. Placement can't be bought.

x402 Video Intelligence
YouTube video metadata in one call: title, channel name and id, duration, upload date, view and like counts, description, thumbnail URL, the chapter list with start and end times, and the language plus kind (manual or auto) of every available caption track. Never downloads media. Use it to check a video's length or caption availability before paying for a transcript, or to enrich a bare video link with real facts.

x402 Video Intelligence
YouTube video transcript extraction with per-segment timing. Returns the caption track as timed segments (start, duration, text) plus the full plain text, or as SRT subtitles. Uses the creator's manual captions when they exist and falls back to YouTube automatic captions. Never downloads media, so it stays fast and light. Cached per video and language. Use it to summarize a talk, quote a video with timestamps, or search inside video content.

x402 Web Search
Ranked news brief for any topic, refreshed every 15 minutes: the most-corroborated recent headlines, each with source, URL, published time, age in minutes and an importance score computed from how many independent news engines surfaced it and how fresh it is. Zero-LLM, deterministic, no API key. Use it for a market or crypto morning brief, monitoring a company or keyword, or grounding a summary in dated sources.

x402 Web Search
Fetch one public web page and return its readable content as clean text or markdown, with JavaScript executed, so the result reads like the page a human sees. The retrieval half of research: pair it with /search to go from a query to grounded page text. Returns the content, its length, the final URL and the HTTP status. Truncate with max_chars.

x402 Web Search
Run up to 5 web searches in one call and get a results block per query. Saves the round trips an agent would otherwise make when a task needs several lookups (multi-entity research, comparison, fan-out). Same engine as /search; each query returns up to 10 trimmed results.

x402 Web Search
Web search that returns structured SERP results as JSON. Runs on a dedicated SearXNG instance aggregating multiple engines, so there is no per-engine API key, quota or HTML scraping to manage. Each result carries title, URL, snippet, the source engine and a published date where available. Choose general web, news, or image results, up to 10 per call. Use it to ground an answer in current web sources, research a topic, or monitor news on a query.

x402 Web Search
Academic and scientific paper search, keyless: one query across arXiv, PubMed, Semantic Scholar, OpenAlex and Google Scholar via a dedicated SearXNG science index. Each hit carries title, URL, authors, publication date, journal/venue, DOI and a PDF link where available, plus a snippet. Use it for a literature scan, citation hunting, or grounding a claim in primary research.

x402 Web Search
Drop-in web search API: POST the common search body (query, numResults, includeDomains, excludeDomains, contents.text) and get results with id, url, title, publishedDate and page text. Point an existing neural-search SDK base URL at https://search.cyberwarex.com/v1, no key. Keyword engine, Google-grade results on paid calls. Up to 10 links, text for the top 5.

x402 Web Search
Web search with the page text already extracted: one call returns the top results for a query AND the readable content of each result page (JavaScript rendered, markdown or text, truncated to max_chars). What an agent needs to answer a question with sources without a second round of fetches. Up to 5 pages per call, fetched in parallel.

x402 Web Search
Research answer: ask a question in plain language and get a short written answer from the live web, with numbered citations. It searches, reads the top result pages, and writes 2 to 4 sentences using only what those pages say; every claim carries the number of its source, and an answer the sources cannot support is refused. When the sources do not answer the question you are not charged. Use it instead of search, then fetch, then read.

x402 Web Tools
Check a web page for changes: each call compares the page's readable text with your previous check of the same URL (kept per paying wallet for 90 days) and returns whether it changed, when you last checked, and the added and removed lines. The first call records the page. Use name to keep several watches of one URL apart.

x402 audit of a seller
x402 audit of a seller. Audit an x402 seller before an agent buys from it: decodes the endpoint's 402 terms without paying, OFAC-screens each payTo address, reads its account type and nonce on the payment network, checks the seller domain's age and trust flags, and flags non-USDC assets and high prices. One block, review or pass verdict with reasons. Never signs. Screening aid, not legal advice. Use before the first payment to an unfamiliar x402 seller.

x402 market pulse
Live cross-provider x402 market sentiment. topProviders: the top x402 sellers ecosystem-wide, ranked by REAL on-chain activity (Agent402 included and flagged isSelf:true). Pick the lens with sort: 'usd' (revenue, default - whale-skewable), 'buyers' (distinct paying wallets - broadest adoption/reach), or 'calls' (raw volume). Every row carries all metrics plus callsPerBuyer (intensity), so revenue and actual ecosystem usage are both visible.

x402 seller dossier
Everything Agent402 knows about one x402 seller origin, in one read: identity and crawl history, the catalog with the provenance of every price (live-402 or manifest, when it was read, whether it is stale or disagrees with the seller's own declaration), advertised wallets against the wallets that were actually paid (own chain evidence, inherited wallets, shared claims), settlement evidence per source (our Base leaderboard, Coinbase Bazaar, Solana SPL credits, MPP transfers), the router's own.

x402 seller payability check
Buy one call from an x402 seller endpoint right now and report exactly what happened: the unpaid call's status, the 402 decoded (accepts, chains, payTo, asset, price), whether the accept's EIP-712 domain name matches the token it names (the defect that silently makes a whole catalog unpayable), whether a stock client's signed payment was accepted, the settlement receipt and transaction, a slice of the response body, and the time each leg took. Ends in plain-English flags, never a score.
