## Datasets

- npm-vuln-digest ($0.02/fetch, daily): The latest ~100 npm security advisories, normalized for machines: severity, CVSS, affected packages, vulnerable ranges, patched versions. Derived from the GitHub Advisory Database (CC-BY 4.0, attributed). GET https://datastand.dev/api/data/npm-vuln-digest -> 402 with x402 payment requirements.
- dev-signals ($0.02/fetch, daily): A ranked, tagged digest of the last 24h of high-signal developer news (AI, devtools, security, infra) with scores, links, and discussion volume. Built from public Hacker News data. GET https://datastand.dev/api/data/dev-signals -> 402 with x402 payment requirements.
- bazaar-market-report ($0.05/fetch, daily): Daily market intelligence on the x402 Bazaar: index size and composition by network/scheme, USDC price distribution percentiles, real usage stats (share of resources with 30-day calls, top-20 by calls), new-listing rate, churn-risk aging, and domain concentration. Aggregated from the public CDP discovery API. Rebuilt daily by an autonomous agent. GET https://datastand.dev/api/data/bazaar-market-report -> 402 with x402 payment requirements.
- llm-pricing ($0.05/fetch, weekly): A verified, machine-readable table of current LLM API pricing (input/output per MTok, cached-input where published) and context windows across major providers (Anthropic, OpenAI, Google, DeepSeek, xAI). Every row carries its official source URL and verification date. Curated and re-verified weekly by the operator agent. GET https://datastand.dev/api/data/llm-pricing -> 402 with x402 payment requirements.
- bazaar-search ($0.005/fetch, live): Keyword search over the x402 Bazaar discovery index (the ~8,000 most-used of 15k+ resources, refreshed daily): find services by text query with price and usage filters, ranked by unique payers. The discovery endpoint itself has no search — this is it. GET https://datastand.dev/api/search/bazaar -> 402 with x402 payment requirements.
- llm-route ($0.005/fetch, live): Cheapest-model router: send your token workload and get every current LLM ranked by estimated USD cost, with per-MTok prices, cached-input rates, and context windows.
