Bill Spike Finder — Finds the loops behind a bill spike or an unexpected bill. Reviews a web app's code and config for loops and repeats that run up the bill on their own on Vercel, Turso, Cloudflare Workers and D1 and paid AI APIs. Finds two schedulers on one job, retries without a cap, work that triggers itself, client polling and React render loops, caches cleared on every write, middleware running on every static file, queues that resend failures forever, image settings that multiply transf…

DNS lookup API: A, AAAA, MX, TXT, NS, CNAME and CAA records of any domain in one call, with TTL and DNSSEC validation, via public DNS-over-HTTPS. Domain and network recon for agents.

WHOIS lookup and domain availability check (RDAP): registered or available, registrar, creation and expiry dates, days until expiry, status and nameservers. Registrant contacts are never returned.

MX records, SPF and DMARC check of a domain: does it accept email, its mail servers, SPF policy, DMARC policy and detected deliverability issues. DNS only, no SMTP.

Retirement calendar for AI models across platforms: shutdown dates, 'not sooner than' floors, states and recommended replacements from the official Anthropic, OpenAI and Amazon Bedrock deprecation pages, plus Azure, Vertex, Gemini and others, recorded daily so moved dates show. The same model often retires on different dates on different platforms. One model with model=, or upcoming shutdowns. Signed.

Returns model health status and per-chain training stats (sequence count, last retrain time) — check before relying on sequence-anomaly scores for a given chain.

Batch URL validation for AI agents. Check up to 10 citations, links, websites, or API endpoints in one payment. Returns reachability, exact status, latency, content type, final URL, and safe redirects; partial failures stay isolated.

Fresh operational audit of any public agent or paid API: reachability, latency, HTTP status, x402 challenge, price/network/payTo, OpenAPI, agent card and MCP manifest. Returns a 0-100 score, verdict and issues. Try GET /agent-health/sample.

DNS lookup: A, AAAA, MX, TXT, NS records

IPv4 CIDR calculator: network, broadcast, netmask, wildcard, usable host range and count, plus optional contains-IP membership check.
