POST http://algo.netintel.dev/ai-image/generate · 1 observation
AI image asset generator for agents: app icons, logos, avatars, social graphics, OG images, blog thumbnails, banners, product mockups, web images, illustrations. A Claude Haiku pass optimizes the prompt for the use case, writes alt text, scores the request, and screens content policy before the paid render (OpenAI gpt-image-1). Returns a self-contained base64 PNG data URI plus rich metadata (revised prompt, alt text, score/grade, warnings). One 1024px-class image per call.

GET http://algo.netintel.dev/currency-exchange/convert · 1 observation
Convert any amount between 32 fiat currencies (live European Central Bank rates) and major cryptocurrencies (BTC, ETH, USDC, SOL, ICP, CELO and more, live Coinbase spot rates) — fiat↔fiat, crypto↔fiat, and crypto↔crypto all work. Returns converted amount, exchange rate, inverse rate, rate date, and rate source so agents can price and invoice across fiat and crypto without a paid forex API.

GET http://algo.netintel.dev/domain-availability/check · 1 observation
Check if a domain name is available for registration by querying RDAP and DNS — pass a bare name (e.g. mybrand) to sweep it across 10 popular TLDs simultaneously, or a full domain (e.g. mybrand.com) to check that single domain — returns registration status, expiry date if registered, and available/taken TLD lists so agents can find the best domain for a brand or project.

GET http://algo.netintel.dev/domain-report/analyze · 1 observation
One call returns a complete intelligence profile for a domain — WHOIS registration, DNS records, SSL certificate, detected tech stack, and blacklist status — aggregated into a single risk-scored report so agents can fully vet a domain without orchestrating five separate lookups.

Counts describe directory coverage, including testnets. Each resource groups the same URL, HTTP method or MCP tool across sources. A catalog sighting records published terms. A live 402 records the endpoint’s reply to an unpaid request.
