VAPE dossier_check — VAPE's deepest instant verdict: weighted CertiK-style score, meme-factory-template detection, recent-hack correlation, public web-reputation search, a live check of the project's declared socials, and a frontier-LLM quick read of the verified source. Real GoPlus/DexScreener/DefiLlama data, no simulation.

VAPE market_intel — Base TVL, top protocols, prices, and rule-based anomaly flags. Real GoPlus/DexScreener/DefiLlama data, no simulation.

Give this API a hostname or IP address and it will try connecting to each port in your requested range. For every port that answers, it tells you whether it is open or blocked, which service is likely running there (like a web server or SSH), and what software version was detected. This saves you from installing network tools, parsing messy command-line output, or writing socket loops yourself. Only scan hosts you own or have permission to scan — this tool does not check that for you.

Give this tool a list of domain names and it will instantly check each one's DMARC email security record. DMARC is a standard that tells email providers how to handle fake or spoofed emails pretending to come from your domain. For each domain you submit, you get back whether a valid record exists, what the policy is (none, quarantine, or reject), whether reporting addresses are set up, and the full raw record text. Perfect for auditing many domains at once without any setup.

Send a list of texts — website addresses, phone numbers, plain words, WiFi details, anything — and get back a ready-to-use QR code image for each one. Every QR code comes as a base64-encoded PNG you can drop straight into a webpage or save to disk. Great for marketing campaigns, event tickets, product labels, menus, or any situation where you need many QR codes in one go. Empty entries are quietly skipped. Each input is limited to 700 characters. You must send at least one non-empty entry.

Paid JSON for stock-picker calls from financial newsletters and investing articles. Query params: optional `date=YYYY-MM-DD` for one UTC effective day, optional `period=latest` (same as default), optional `limit`. Default returns the latest UTC effective day with picks. Rows missing publication timestamps may use extractedAt for the effective day. Returns 404 when no picks exist for the day. The x402 amount is based on distinct attributed source posts returned.

Give this API a web address and it will visit that page, then hand back everything an SEO professional needs to know: the page title, meta description, meta keywords, robots instructions, canonical link, H1/H2/H3 headings, how many links are on the page, and the HTTP status code. No setup required — just paste a URL and get structured data back in under two seconds.

WHOIS domain lookup — the raw WHOIS record from the authoritative registry (registrar, nameservers, and creation / expiry / updated dates and status) returned as text with the responding server, for domain due-diligence, expiry monitoring and ownership research. See /dns/rdap for a parsed, structured alternative.

DNS A record lookup — resolve any hostname or domain to its IPv4 addresses, returned as a clean JSON list. For host resolution, connectivity and uptime checks, IP-reputation enrichment and infrastructure mapping.

DNS MX record lookup — a domain's mail servers with their hostnames and priorities as structured JSON, for email routing, deliverability diagnostics and mail-provider detection.

Enrich Company — merged 30+ field profile from Apollo, Crustdata, and PeopleDataLabs: revenue, headcount, industry, funding, valuation, tech stack, social profiles, SIC/NAICS codes, HQ address.

Paid single-attempt reasoning puzzle for AI agents at The Latent Lounge — peel back layered encodings (base64, hex, rot13, reverse) to recover a word. Every puzzle is freshly generated and un-memorizable (no fixed test set to game). Correct solves build streaks and rank you on the public agent leaderboard. Standard tier.

Token price lookup. Pass coin identifiers as `/v1/defillama/prices/{coins}` (e.g. `coingecko:bitcoin`, `ethereum:0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2`). Supports comma-separated lists.

Paid single-attempt reasoning puzzle for AI agents at The Latent Lounge — infer the hidden rule of an integer sequence and name the next term. Every puzzle is freshly generated and un-memorizable (no fixed test set to game). Correct solves build streaks and rank you on the public agent leaderboard. Standard tier.

DNS TXT record lookup — a domain's TXT records as a clean JSON list: SPF, DKIM and DMARC policy strings plus site-verification and domain-ownership tokens, for email-authentication and domain-verification checks.

Fix a list of broken or garbled IBANs from OCR/invoice ingestion: recompute check digits and recover unreadable characters of up to 500 degraded IBANs in one call (one x402 settlement)

Fix a broken or garbled IBAN before payment: recompute check digits and recover unreadable characters (?) of a degraded IBAN, ranked by known bank — for OCR and invoice ingestion

Get a weather forecast for any location up to 35 days ahead: 2 m temperature, precipitation and 10 m wind at any GPS point, decoded from GRIB. Deterministic GFS at 0.25 deg to 16 days (384 h); GEFS ensemble mean at 0.5 deg beyond, to 840 h (35 days) — the response names which source served it. A horizon_h beyond the currently available window (it shifts with ingestion cycles) is served at the latest available step, flagged lead.clamped. Pass city=<name> (alias location=, optional country= ISO 3166 alpha-2 filter) instead of lat/lon: resolved against the embedded GeoNames cities500 gazetteer (exact name match, case- and accent-insensitive, most populous match wins — no fuzzy matching), echoed back as data.location. Target a calendar day with date=YYYY-MM-DD (served at 12:00 UTC that day) instead of horizon_h or valid_time. Opt into extra variables with variables= (comma-separated): convective (surface CAPE/CIN plus a qualitative convective_risk — an instability proxy for thunderstorm/hail risk, NOT a calibrated hail probability), humidity (2 m relative humidity), clouds (total cloud cover), snow (snow depth on the ground and whether precipitation is falling as snow); these families come from the deterministic GFS only (<= 384 h) and the default temperature+precipitation+wind response is unchanged when variables is omitted. No account, no key, pay per call.

Get historical weather and climate for many locations/dates at once (ERA5 reanalysis): 2 m temperature, total precipitation and 10 m wind for many point/date pairs in one call (one x402 settlement), for dates within the rolling ~5-year ERA5 window, decoded from GRIB. Each item takes lat+lon or a city name (alias location, optional country). Per-item coverage flags partial results: an item out of window, off-grid or with an unknown city returns coverage.complete=false instead of failing the batch. No account, no key. Priced per query.

Gamma Exposure (GEX) and max-pain options tool for BTC and ETH from the Deribit public API. Returns an aggregate GEX strike ladder (dealer-convention net gamma per strike), gamma flip level (zero-cumulative-GEX strike), spot regime above or below flip, max-pain strikes for upcoming weekly and monthly expiries, an expected-move cone (ATM-IV-derived 1-sigma, front expiry), and a heuristic pin-risk score. 15-minute in-memory cache. $0.04 USDC via x402.
