  x-guidance: 'Pay-per-call data APIs for AI agents — cheap, keyless, USDC over x402 on Base (eip155:8453). Each paid GET returns HTTP 402; pay and retry with the X-PAYMENT header. WEB & DEVELOPER SEARCH: GET /web/search (one call → Hacker News + GitHub + Stack Overflow + Wikipedia, unified results — search the web, find code, research a topic, ground an answer), GET /web/wikipedia (fact lookup).

AI-VISIBILITY / GEO (uniquely ours — does AI recommend a brand?): GET /brands/check, /category/ranking, /crypto/ai-visibility, /sales/qualify. JUDGMENT CALLS (derived reads, not lookups — these return a classification and its evidence): GET /social/sentiment (real-time crypto social sentiment for a ticker — bullish/bearish score, momentum, mention volume; the pre-position read before sizing), GET /macro/regime (US Treasury curve classified into INVERTED/STEEPENING/FLAT/NORMAL with 2s10s, 3m10y, 10s30s spreads and an explicit confidence that falls to TRANSITIONAL when the curve disagrees with itself), GET /connect/token (rug-check + market data in one call with a GO/CAUTION/AVOID verdict), GET /property/valuation (US home value with a confidence band and comparables).
