Counters

20 observations, 1 of them a change, fewer than the 3 a trace needs

How big is this endpoint among the ones like it?

Calls counted in the trailing thirty days across the 1,632 endpoints in Search that carry counters, binned on a logarithmic scale because the range runs over five orders of magnitude. The marked bin is this endpoint, at 6: 282 in the category are counted higher and 1,349 lower.

No trace is drawn of this endpoint’s own volume. Its counters have changed 1 time across 20 observations, and 3 changes are the fewest this site will draw a trace through, because two points and a guess are not a series. Every observation is in the JSON.

In words

semantic search answered HTTP 308 rather than 402 at the sweep of 2026-09-13; the recorded state is fail.

x402.fuchss.app serves semantic search, a POST endpoint that TOLL places in search, listed in neither registry at the last pull.

On Base, semantic search asks 0.001 USDC per call.

semantic search takes a json body with the fields limit and query.

A response from semantic search, as declared, includes note, count, query, matches and generatedAt.

semantic search drew 6 calls from 6 unique payers in the trailing 30 days, every call from a different payer.

semantic search was last called 6 days before the snapshot.

No other listing shares its host.

semantic search is the cheapest of 1,638 comparable listings in search; none asks less.

Closest in price to semantic search within search: tools search at win.oneshotagent.com and base ecosystem news at x402.ottoai.services.

The wallet paid by semantic search is the payee of 11 endpoints across 2 hosts.

semantic search out-counts 80% of the 1,632 endpoints in search that carry counters.

The seller's tags on semantic search are x402, trust, reliability and monitoring, and its label is "data".

semantic search was missing from the Coinbase registry at the pull of 2026-09-13, confirmed at the pull of 2026-09-13; that is registry presence, not liveness.

The price of semantic search is declared by 164 other listings in search too.

What the listing says

Semantic search across the entire monitored x402 catalog. Given a free-text query (e.g. "weather forecast", "image generation", "EVM gas price oracle"), returns the closest endpoints by advertised purpose. Ranking is deterministic: cosine similarity bucketed to whole percentage points first (80.3% and 80.5% are the same bucket), then trust score, then described-before-undescribed, then endpoint id. Matches below a 0.5 cosine-similarity floor are dropped entirely, so a query can return fewer than the requested limit (or none). Endpoints that advertise no description are still matched: they are embedded from their service name and URL path tokens instead of a written description (host name as a last resort). The exact effect of a missing description: no fixed point deduction and no direct similarity malus; the only deterministic penalty is the described-before-undescribed tiebreak (at equal similarity bucket AND equal trust score, a described endpoint ranks first). Beyond that it is purely indirect: the shorter fallback text typically yields lower cosine similarity than a prose description, so such endpoints tend to land in lower similarity buckets, by a query-dependent amount. Each match carries its resource URL, trust score, grade, cosine similarity (0-1, raw value; ranking buckets it), advertised description when present, and a free endpoint-page URL. Matches also carry the advertised price as machine-readable fields: amountUsd (null when not advertised) and priceCeiling (true when the endpoint uses the x402 'upto' scheme, i.e. amountUsd is an authorization ceiling and the real charge is typically lower). This is a DISCOVERY product: it deliberately carries no verdict, recommendation or flag detail (the per-endpoint trust report sold at /v1/x402-trust carries those). The query is embedded with the same model as the catalog, so phrasing the capability you need works better than guessing keywords.
