Query a JSON document with a JSONPath expression.

$0.0002/MB. Infer a JSON Schema or SQL DDL straight from your data — skip hand-writing schemas. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

Validate a JSON document against a JSON Schema.

Snapshot a list of US-listed tickers at once: for each symbol, the company name, market session, current price, day change and percent change, day OHLCV with VWAP, and previous close. Pass a comma-separated list via `?tickers=AAPL,MSFT,NVDA` (up to 250). Built for pricing a watchlist or portfolio in a single request. From x402stock, a market & economic data API (x402, USDC).

DNS and list based verification. Never claims that a mailbox exists without evidence: without an SMTP probe the verdict for a routable address is "unknown", not "valid".

Tournament fixtures, filterable by team, opponent, and date range.

Generate images from a text prompt with xAI's Grok Imagine quality tier. Returns hosted image URLs.

Generate a random EUI-48 MAC address. By default it is locally-administered and unicast (safe for testing); set `local:false` for a universal-bit address or `multicast:true` for a group address.

Live top stablecoin and ETH APY yields on Base, pre-sanitized for autonomous AI agent execution.

Full descriptive summary of a numeric sample: count, sum, min/max/range, mean, median, mode(s), variance, standard deviation and the quartiles (q1/q3/iqr). Set sample=true for the sample variance/stdev (÷ n-1) instead of the population form (÷ n).

Sanitized BTC, ETH, and SOL Polymarket probability spreads and liquidity depth in basis points.

Open an SSL/TLS connection to a host and report its certificate — issuer, subject, validity window, days remaining, SANs, fingerprint and trust status.

Scan source code or configuration text for hardcoded secrets: AWS access keys, GitHub/Slack/Google tokens, Stripe and OpenAI keys, PEM private-key blocks, JWTs and high-entropy secret assignments. Placeholder values are filtered out. Each finding gives the rule, a severity (critical/high/medium/low), line and column, entropy and a masked excerpt. Offline and deterministic.

Render text (URL, vCard, Wi-Fi config, …) as a QR code — SVG string or PNG data URL.

Single models are everywhere. This is the disagreement between them: per hour a median with a p15/p85 band, the full min/max spread, how many models still carry that hour, an agreement score, rain probability derived from pooled ensemble members rather than one deterministic run, a frost assessment, and the official DWD warnings in force for the point.

Independently fetch, hash, timestamp and archive a URL or API response; returns a signed certificate. Merkle-anchored on Base hourly. Neutral third-party evidence for agent commerce disputes.

Spell text using the NATO/ICAO phonetic alphabet (A→Alfa, B→Bravo, …), including digits and spaces (→Space). Characters with no phonetic spelling are clean 400s.

Fetch a site's robots.txt and evaluate crawl permissions: given a URL (plus optional extra paths) and a user-agent, return whether each path is allowed or disallowed, the rule that matched, the user-agent group, the crawl-delay and any declared sitemaps. Implements the Robots Exclusion Protocol (RFC 9309) with longest-match-wins, Allow-over-Disallow tie-breaking and * / $ wildcards.

Generate images from a text prompt with xAI's Grok Imagine quality tier. Returns hosted image URLs.

Use to track one tokenized equity by xStock symbol (AAPLx) or underlying ticker (AAPL): the on-chain Raydium CLMM pool price from the public Solana ledger, the per-share price after its Token-2022 scaled-UI multiplier, the underlying's live quote, and the premium/discount percent. List every tracked symbol via /xstocks. From x402stock, a market & economic data API (x402, USDC).
