Find recent topic news with deduplicated source links and optional source-linked headline highlights; retrieve six annual US-GAAP USD fields by CIK with filing links, same-filing growth checks and optional observed revisions; check supplied CSV and citations; extract public page text, rendering JavaScript in a headless browser when needed; inspect email address syntax and mail-domain DNS. Pay per call with native USDC on Base or Solana via x402, without a separate API key. Wallet-first free trials cover CSV, column-spec, citation and static-page operations.","contact":{"email":"support@mekler.ai"},"x-guidance":"Model inference quotes selected models and the full price before payment. Submit one to20 independent text tasks, use automatic routing or pin a model, then recover private asynchronous results. No streaming, tools or browsing. News search accepts plain topic words and a1\u20137-day GDELT monitoring window. Use monitoring.next_request for a new paid poll with a45-minute overlap and bounded seen-link/headline history. No-new-links polls are charged0.01 USDC. Its optional digest quotes returned headlines; full articles and verified publication dates are unsupported. Source failures are uncharged; valid zero-match searches are completed and charged. Conformance scans return 202 first: retain the recovery capability, poll until result-ready, then request a quote and pay once for the stored report. Cached reports and check definitions are free. Financial facts accept a CIK and one to three annual periods, with optional include_revisions. Inspect coverage before paying; growth checks are mechanical and revision history is bounded. No quarterly data, accounting-comparability assurance or restatement explanations. Choose CSV validation to check supplied data against typed column rules; use column-spec validation to check those rules before use. Citation overlap inspects supplied URLs, HTML and declared lineage; it does not fetch sources or judge truth or independence. Static page extraction fetches one public static HTML page without running scripts. Rendered page extraction loads one public page in headless Chromium for content that appears only after JavaScript runs; no login, interaction or PDF. Failed, blocked or empty pages are never charged. Email checks do not verify mailbox existence or delivery. Read the operation schema, example and complete service guide before calling. For synchronous paid calls, POST the intended JSON without PAYMENT-SIGNATURE to get an x402 quote, then sign and resend the same body. Both page extractions and financial facts also return an encrypted payment_request; sending it instead pays for exactly the quoted result. If a response is lost, retry the same paid-request body and proof. Free trials use the separate wallet-first trial guide at https://api.mekler.ai/trials/offer and exclude news search, financial facts and rendered pages.
