Paid services matching “space”

Current space-weather conditions — normalized NOAA SWPC Kp, solar wind, magnetic field, and X-ray flux used for solar-flare monitoring, with observation times and freshness.

Complete structured package for one illustrated classic of early science/engineering (1588-1748): verified public-domain scan, full metadata, curated description, full-text OCR link, IIIF manifest, and page-image URL template. Works: Ramelli machines 1588, Agricola De re metallica 1621, Hooke Micrographia 1665, Newton Principia 1687 & Opticks 1730, Euler Introductio 1748. Param: ?id=<work_id>

Dedicated satellite tracking API for agents: list CelesTrak TLE catalog groups (ISS, weather, and more), get live propagated positions for a whole catalog group, and predict the next pass over an observer latitude/longitude using NORAD catalog IDs. Outbound CelesTrak fetch only; no shell access.

Format, dimensions, megapixels, bytes, channels, transparency, color space, bit depth, DPI, orientation, animation and pages, ICC profile, and EXIF camera details (make, model, date taken, exposure, aperture, ISO, focal length, GPS position) of an image at a URL.

Validate a number by the Luhn (mod-10) algorithm — the scheme behind credit/debit card numbers and many IDs. Spaces and hyphens are ignored. A mismatched check digit is a successful { valid: false }.

Encode text into international (ITU) Morse code. Letters are separated by spaces and words by "/". Supports A-Z, 0-9 and common punctuation; unsupported characters are clean 400s.

Use when you need image embeddings or text embeddings in one 2048-dimension space for retrieval, RAG, semantic search, clustering, or dedup (Qwen3-VL-Embedding-2B, OpenAI-compatible). Batch up to 256 items per call, served 32 at a time. An x402 call is $0.002 when the request includes images, $0.001 for text-only. USDC on Base. 400 is a bad body, 413 is over 48 MiB, 429 means busy (Retry-After).

Deterministic, paid-per-render SVG bar chart generator for LLM agents. Accepts labeled scalar data and layout options, performs exact geometry math (min/max normalization, nice-interval y-axis ticks, label spacing, bar-width distribution), and returns schema-valid, escape-correct SVG with identical input always yielding byte-identical output.

How is TradFi trading right now, next to crypto? Any list of US equity symbols plus the S&P 500, NASDAQ and Dow, each returned with price and 24h change already computed and in the same shape as our crypto routes, so both sides of a comparison arrive from one call.

Encodes text to base64 or decodes base64 to text, returns a JSON object with the result string

Text-to-image generation on Venice models (Flux, SD3.5, GPT-Image, HunyuanImage, and more), paid per request in USDC on Base via x402, no API key. Charge is catalog unit × variants (1–4). A bare unpaid probe (no model) quotes default venice-sd35 (from $0.01; flux-2-pro $0.015). S

Audit text for malicious AI-skill patterns. Requires `content`. Nothing to audit — crawling, or discovering this endpoint cold? POST /audit/registry runs the same scanner over the newest servers in the official MCP registry: no input required, $0.005.

Propagates a circular two-body orbit from altitude, inclination, RAAN, and initial orbital phase; rotates Earth at a fixed sidereal rate; and samples ground-station elevation. It ignores eccentricity, perturbations, epoch-dependent Greenwich angle, refraction, ellipsoid shape, terrain, and antenna masks, so it is a planning estimate rather than operational ephemeris.

Extract clean, LLM-ready Markdown or plain text from up to 5 public webpage URLs. Removes page boilerplate and returns structured per-URL results for AI agents, RAG ingestion, research and summarization.

One substance, with the cross-axis derivation: what every other jurisdiction (JP, EU, US, Codex, IARC, JECFA, EFSA) says about it, with per-cell sources, kept separate from what was derived

Risk check for an EVM contract/token address

Single-fact: current Monero chain height + sync status. Sourced from a live operator-run monerod node.

7-day x402/Solana market analytics from the only complete settlement ledger of this market: seller leaderboard by USDC earned, price-point zone distribution, repeat-buyer structure, daily volume trend. Competitive intel for anyone selling or building on the x402/Solana rail.

Full-domain intelligence report in one call: complete DNS sweep (A/AAAA/MX/NS/TXT/SOA/CNAME), RDAP registration data (registrar, dates, statuses), DNSSEC presence, mail posture summary (SPF/DMARC/DKIM selectors), TLS certificate snapshot (issuer, expiry, protocol), Certificate Transparency subdomain census, and HTTP probe (status, redirects, https enforcement, server header) — each section scored,

Evidence-ranked root-cause analysis from issue text, logs and supplied code context.

Use this when you need a fast cited answer, not deep research: one live web search, relevance-ranked sources, snippet-level digest with 3-6 cited key points in seconds. No API key, no signup — x402 per-call payment only. For full-page depth use the $0.05 Research Brief on the same origin.
