The first stop when an email is hitting the spam folder. Also on x402 Bazaar - POST/v1
/insider-reportNo price listedName a US ticker and get one cited insider-flow report: every Form 4 against the company in the window with the actual transactions parsed from the filings - open-market buys and sales (who, when, how much, at what price) separated from awards, option exercises and tax withholding - aggregated per insider and as a net flow, with a grounded signal read and a downloadable transactions appendix.

/llm-contextNo price listedWeb search that returns READY-TO-USE grounding text, not links: for one query you get the passages an independent search index extracted from the pages it ranked, flattened into chunks with their source URL and title and an approximate token count, under a token budget you choose (1024-32768, default 4096). Use it to ground a model or a RAG pipeline in one call, where search + extract would take several. Also on x402 Bazaar - POST/api
/skill /any-to-markdownNo price listedConvert anything at a URL - HTML, PDF, or an image - to clean markdown. The 'I have a URL but it might be any content-type, give me markdown either way' workflow: HEAD-detect the content-type, branch to the right deterministic extractor (article extract for HTML, pdf-to-markdown for PDFs, OCR for images), and report token/word stats on the output so the caller can budget the result against an LLM context window. Also on x402 Bazaar - POST/api
/polymarket-price-historyNo price listed - POST/api
/slugifyNo price listedTurn any text into a URL-safe slug (lowercase, hyphenated, diacritics stripped). Also on x402 Bazaar - POST/api
/mev-recent-blocksNo price listedLast N MEV-Boost-built blocks from a major MEV-Boost relay's public data API. For each block: slot, block number/hash, builder pubkey, proposer pubkey, gas used/limit, ETH paid to the proposer, and tx count. Use to monitor block-builder market share, proposer revenue, or to correlate an arbitrage opportunity with the block it landed in. Also on x402 Bazaar - POST/v1
/judgeNo price listedAsk a typed question about any content and get an answer your code can branch on, not prose to parse. Send state (the content, a string or object) and questions (your own ids mapped to question objects); get back answers keyed by those ids. Three question types: choice (pick one of your named options: returns choice, probabilities per option and confidence), score (a position on levels you describe, lowest first: returns score as a fractional level index, probabilities per level index. Also on x402 Bazaar - POST/api
/html-metaNo price listedExtract <title>, <meta description>, OpenGraph/Twitter cards, canonical URL, and JSON-LD blocks from an HTML string. Distinct from /api/meta which fetches a URL - feed this the HTML you already have (from /api/render, /api/extract.body, or your own fetch). Also on x402 Bazaar - POST/api
/skill /schema-evolutionNo price listedThe 'did this API contract change in a way that breaks our integration?' workflow. Diff two OpenAPI snapshots structurally, lint the new one for agent-readiness regressions, extract the endpoint surface for inventory comparison, validate a known-good payload against the new contract, and summarize security-relevant changes. Six tools, one go/no-go answer on whether the upstream API broke us. Also on x402 Bazaar - POST/api
/skill /contact-verifyNo price listedVerify an email address is deliverable - syntax validation plus MX record check on the domain. Contact verification skill pack: one x402 payment runs 3 underlying tools (email-validate, dns-lookup, spf-check); partial-success per step. Also on x402 Bazaar - POST/api
/html-tableNo price listedExtract a <table> from an HTML string as JSON rows (header-keyed) or CSV. Useful for prices, schedules, sports stats, or anything an agent has already fetched as HTML. If multiple tables match, the first is used. Also on x402 Bazaar - POST/v1
