It is deployed as a Cloudflare Worker and is listed as an x402-protocol endpoint.\n\nHowever, during probing the endpoint returned HTTP 404 on both GET and POST requests rather than the expected 402 Payment Required challenge. The origin domain's root, docs, API, pricing, and README pages all display a generic Cloudflare placeholder (\"There is nothing here yet\"). No OpenAPI schema, pricing information, documentation, or usage examples were found anywhere on the site.\n\nGiven the complete absence of a working 402 challenge and the placeholder state of all pages, this endpoint appears to be either not yet deployed, temporarily offline, or abandoned. The name suggests it would serve PubMed trend data, but no concrete details about request/response format, pricing, or capabilities can be confirmed from the available material.","tags":[],"capabilities":["pubmed-data","biomedical-trends","research-snapshot","x402-payment"],"categories":["search","bio"],"synonyms":["PubMed trends","biomedical literature trends","PubMed snapshot","research publication trends","medical research data"],"warnings":["Endpoint returned 404 on both GET and POST — no x402 challenge detected; endpoint appears not live.","All pages on the origin domain (root, /docs, /api, /pricing, /README) return a generic 'nothing here yet' placeholder.","No OpenAPI schema, documentation, pricing, or usage examples available.","Endpoint may be undeployed, under construction, or abandoned."],"endpointUrl":"https://pubmed-trends-x402.ben-miles2.workers.dev/api/v1/snapshot","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x8C05121C9617f8960Cf5b7451103192F32DE8ddE","amount":"10000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.100","qualityRationale":"The endpoint returned 404 on both GET and POST (no 402 challenge), and every page on the domain shows a Cloudflare placeholder.
