Returns the paid x402 request for your input (GET /v1/email/verify, $0.01 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. Checks one mailbox; for a list use check_email_batch. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price. First call each day returns the data itself, free; later calls return the paid request.
check_email_batch
Use when you must check a list of email addresses before a mailing or import: up to 25 addresses in one POST, each checked exactly like /v1/email/verify. Returns the paid x402 request for your input (POST /v1/email/verify/batch, $0.25 per call; schema linked). POST that JSON body to the URL with an x402 or MPP client to get the data. Bad input is refused before any charge. For one address use check_email_address. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price.
url
url_uptime_ping
Use when you need to know if a URL is up right now (uptime ping, health check, link check): one HEAD request from a Cloudflare edge, up to 4 redirects; returns ok, status, latency_ms, tls. Returns the paid x402 request for your input (GET /v1/uptime/ping, $0.01 per call; schema linked). Call that URL with an x402 or MPP client to get the data. Bad input is refused before any charge. For several URLs use url_uptime_ping_batch. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price.
url_uptime_ping_batch
Use when you monitor several endpoints: up to 10 http(s) URLs in one POST, each checked exactly like /v1/uptime/ping (status, latency, redirects, TLS, server) from Cloudflare's edge. Returns the paid x402 request for your input (POST /v1/uptime/ping/batch, $0.10 per call; schema linked). POST that JSON body to the URL with an x402 or MPP client to get the data. Bad input is refused before any charge. For one URL use url_uptime_ping. With an access key (Authorization: Bearer p0k_..., buy at https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/keys/buy?usd=5) the tool pays the call itself, returns the data and deducts the price.
doc
doc_read
Use for reading a web page as clean markdown for an LLM or agent (url to markdown, reader, html to text): POST {url, max_chars} and get {title, markdown, chars, source_url}. Returns the paid x402 request for your input (POST /v1/doc/read, $0.005 per call; schema linked). POST that JSON body to the URL with an x402 or MPP client to get the data. Bad input is refused before any charge.
