What web search APIs cost over x402
Snapshot 2026-10-10
An agent can search the web by the call over x402 and get back a list of results. We index the x402 Bazaar daily, so here is what those listings charge on 2026-10-10. The short version: we found 123 distinct priced web search offers on 92 hosts, the median is USD 0.01 per search, the lowest is USD 0.001 and the highest USD 0.25. Tanod charges USD 0.012 per search, so Tanod is above the median: 87 listings are lower, 3 are the same and 33 are higher. These are listed prices, matched by keyword and reviewed by name and description; we have not tested the endpoints, and they differ in index, result count and what they return (see below).

Prices are per call as listed, in USD, not a measure of result quality, freshness or uptime. The listings are not like for like. Many resell a known provider (Brave, Exa, Tavily, Serper or Google results) and say so; some merge several engines; some return page text next to each result; a few cap results per call and others allow more. Tanod is above the median here: 0.012 against 0.01.

Method
- Source: Tanod's agent index of the x402 Bazaar and PayAI, queried 2026-10-10 (newest listing seen 2026-10-09T04:31:37Z). Internal-only sources, Circle-sourced rows and Tanod's own routes are not used.
- Match: listings with a price above zero whose name, URL or the start of the description mentions web search, SERP, a search engine or a search provider by name. A bulk listing farm with over a thousand rows was left out. That left about 360 distinct URLs, which were reviewed one by one by name and description. Only endpoints whose main job is a general web search that returns a list of results were kept: 123 offers on 92 hosts. Routes that return page text next to each result were kept.
- Excluded: news, image, video, maps, places, shopping, jobs, scholar, patent, social and other vertical searches; routes that return a written answer, report or summary instead of a result list; routes priced per batch of queries; keyword-volume, rank-check and SEO tools; searches of one site or one registry; listings whose text says nothing beyond a generic label; and copies of one route (preview deployments of one host, a second URL for the same route and price, a lite alias). A looser rule would find more.
- Deduplicated by URL. Listed price is the first payment requirement; some endpoints may charge differently by input. Quartiles use linear interpolation over the 123 prices; the median is the 62nd value (0.01).
Where Tanod fits
POST /v1/search takes a query (up to 512 characters) and returns ranked results with title, URL and snippet from one independent index (Mojeek). Optional fields are count (1 to 10, default 10), country (a two-letter region boost) and freshness (day, week, month or year). It returns snippets only: no page text, no written answer, and no news, image or video search. Results are third-party web text and are marked as untrusted. It costs USD 0.012 per call, paid in USDC on Base or Polygon with x402, and 3 free searches per IP per UTC day, a pool of their own. The MCP tool is web_search at https://tanod.dev/mcp. Details are in the web search API guide.
When a priced listing above is the better choice
- You want a lower price: 87 of the 123 listings charge less than USD 0.012, and the lowest charge USD 0.001.
- You need results from a particular engine, such as Google, Bing or Brave, or a provider you already use: many listings name one, and Tanod has a single index.
- You need more than 10 results in one call, or page text, an answer or news, image or video results along with the links: several listings return these, and Tanod returns links and snippets only.
When Tanod fits
- You want a small JSON list of titles, URLs and snippets from an independent index, with a region boost and a freshness filter, and no account or key.
- You want a free allowance to try it (3 searches per IP per day, automatic over MCP) before paying.
- You will fetch the pages you need separately, for example with the page-to-Markdown route, and want search and fetch to stay two steps.
