Example 402 response
Endpoints and prices
| Method | Path | Description | Price | Network | Asset | 402 channel | Captured |
|---|---|---|---|---|---|---|---|
| GET | / | 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. | $0.03 | Base | USDC | header | since 11-05 |
| GET | / | 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. | $0.002 | Base | USDC | header | since 11-05 |
| GET | / | 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. | $0.001 | Base | USDC | header | since 11-05 |
| GET | / | 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. | $0.003 | Base | USDC | header | since 11-05 |
| GET | / | 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. | $0.00435 | Base | USDC | header | since 09-21 |
| GET | / | 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. | $0.01 | Base | USDC | header | since 11-05 |
| GET | / | 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. Prepaid 10 call pack with 10 percent extra credit: bundle endpoint on this host, pack=contents10. | $0.006 | Base | USDC | header | since 11-05 |
| GET | / | Search, fetch and extract in one call: top results with page text and the elements matching a CSS selector. | $0.01 | Base | USDC | header | since 11-05 |

How the score works
What the score read on this service: status online, 99.7% uptime 30d, 1146ms response p95, x402 compliance 14 of 14, $0.001 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.
The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.
Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.
It is a score inside Data, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 472 listings, this one among them: the same 472 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.
Traction is a conservative undercount.
All measured facts
What it does
Web search for agents, paid per call in USDC on Base with x402, no API key and no account. Eight GET routes: web, news and image search, search with the page text already in the results, page contents as text or markdown, paper search across arXiv, PubMed, Semantic Scholar, OpenAlex and Google Scholar, up to 5 queries in one call, a cited answer that is not charged when the sources cannot answer, and search plus CSS selector extract. Calls from 0.001 USDC, spec at /openapi.json and a free sample answer at /sample.
Agent Search (CyberWareX) is a listed x402 Data API. Captured payment terms name Base. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.
