Free proxy API: get one fast, verified-alive proxy (HTTP, SOCKS) filtered by country, protocol and anonymity, for scraping

Check HTTP reachability, status and final URL. Only public HTTP(S) targets are accepted; JavaScript is not executed. Pass url as an absolute public HTTP(S) URL. Keep fresh=false to reuse cache; set f…

Use when an agent must check a domain: does it resolve, who hosts its DNS and mail, is email authenticated, how old is it, when does it expire. Input: domain (e.g. example.com; URLs accepted). Output: JSON DNS records (A, AAAA, CNAME, MX, NS, TXT, CAA, SOA), mail provider, parsed SPF and DMARC, DNS provider, and RDAP registration (registrar, created, expires, age in days, status, DNSSEC). No contact data. Example: ?domain=google.com

Cron job scheduler for AI agents: calls your HTTPS endpoint on a cron expression (recurring webhook, scheduled callback, heartbeat, reminder). ENTRY pack: 20 deliveries for $0.02 ($0.001/delivery). Same service, best rate $0.0005/delivery: https://402cron.com/buy/starter. Also 50000 for $25: https://402cron.com/buy/month. Credits never expire. Your endpoint must echo our challenge (no fixed-reply hooks). HMAC-signed, 3 attempts then auto-pause. No account, no human.

Cron job scheduler for AI agents: calls your HTTPS endpoint on a cron expression (recurring webhook, scheduled callback, heartbeat, reminder). BEST-RATE pack: 2000 deliveries for $1 ($0.0005/delivery) - intro price at the volume rate. Same service, $0.02 entry: https://402cron.com/buy/trial. Also 50000 for $25: https://402cron.com/buy/month. Credits never expire. Your endpoint must echo our challenge (no fixed-reply hooks). HMAC-signed, 3 attempts then auto-pause. No account, no human.

Is Stripe or another SaaS or cloud vendor down right now? Input: ?vendor=stripe (slug, name or domain). Returns status, confidence, active incidents with a summary, official status page, last-checked time and a staleness flag, read live from 60SecMonitor. $0.01 USDC on Base. Untracked vendors return 404 and aren't charged. Up to 25 vendors at once: /v1/status/batch ($0.05). Past incidents: /v1/incidents.

Check whether up to 25 SaaS vendors are down in one call. $0.05 USDC on Base per call. Returns current status per vendor (comma-separated input) at one flat price, plus a list of vendors that are not operational. Not charged if no vendor is tracked or every lookup fails. Don't use this for a single vendor; /v1/status costs less.

Publish agent-generated files, JSON reports, markdown, or text and return a stable public URL.

Live DNS lookup for a domain: returns name, type and records[]. Supported record types: A, AAAA (addresses as strings), MX ({exchange, priority} objects), TXT (each record an array of its strings), NS and CNAME (hostnames). For SPF, DMARC or a full mail-security read use spf-check, dmarc-check or email-deliverability.

Use ping when you need a pass/fail verdict that a URL serves expected content: expected HTTP status (default 200), a required body substring, and/or an exact match on one JSON field. One automated fetch at request time, signed receipt with per-condition results. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402

Compute market snapshot — observed spot prices: cheapest rentable ask per GPU class in USD/hour. $0.25 per query via x402 USDC on Base, Arbitrum One, or Algorand. Asks are ephemeral — re-observe before any decision. Paid output (shape only, no values): {market, generated_at, classes: [{gpu_class, cheapest_rentable, median_price_per_gpu_hour_usd}], caveats}. One payment buys one fresh observation; values are yours only after the payment settles.

Audits agent launches and returns launch review data.

One accepted broken production path. Guarded 12-hour service window begins after cleared payment, accepted scope, reproducible failure, and agreed access. Verified fix or actionable root-cause package, otherwise refund under published terms.

Check whether a website is up right now: HTTP status, response time in ms, full redirect chain, and the SSL certificate's validity, issuer and days until expiry. Use when monitoring a site, diagnosing a broken link, or warning that a certificate is about to expire. A site that is down still returns 200 with up:false and the error. Errors: 400 bad or private URL.

Agent-economy census snapshot: how many known agent/MCP endpoints are alive, dead or unknown right now.

Probe an MCP/agent endpoint: liveness, latency, tool count, auth metadata, price-challenge detection. Real MCP initialize handshake, not a ping.

AI provider health reading from public status pages (currently GitHub): degraded (boolean), level, one reason, per-provider indicator, asOf and sources with attribution. openai and cursor keys return null until 2026-11-12; the anthropic key returns null (no longer measured since 2026-10-20). Additi…

Readings for one AI model in the models.dev catalog (GET /v1/models/report?id={model id}): input/output prices per 1M tokens with 24h and 7d change, standard job cost, context and output limits, modalities, knowledge cutoff, release date, provider listings, the vendor's status-page indicator and in…

One combined reading for agent loops: AI provider health from public status pages, x402 facilitator reachability on the XRP Ledger and recent changes in our record. Returns storm (boolean), level, one reason, asOf and sources with timestamps. Additive measured fields: observed_payment_success (15m/…

AI provider health reading for one provider (GET /v1/decide/provider-health?provider=morph; a model id also works): the vendor's own status-page indicator and active incidents, the share of disturbed checks in the last 24h of our record (checked every 10 min), and a reading field (go, caution, no_g…

Check if a URL is up: status, latency, redirects, title.

Publish agent-generated files, JSON reports, markdown, or text and return a stable public URL.

POST /dns -- Rent <label>.448c.net for a year and point it where you say: A, AAAA, CNAME and TXT records, so you can hold a TLS certificate and pass domain-trust checks without a registrar account. The paying wallet owns the name. Readable afterwards for free at /dns/{name}.
