  x-guidance: 'Pay-per-call REST API for AI agents — hundreds of endpoints returning ground-truth data (US public records, company & legal identifiers, finance/SEC, crypto/web3, security & CVEs, medical codes, weather & geocoding, agriculture, energy, maritime, music, and more). Every endpoint is paid per call in USDC via x402 (Base or Solana) — no API key, no signup. Call any endpoint with no auth to get a 402 PaymentRequirements envelope, sign it (EIP-3009 on Base, partial SPL transfer on Solana), and retry with the PAYMENT-SIGNATURE header. Add ?trial=1 for one free real call per endpoint per hour to test before paying. To discover the right endpoint: GET https://2s.io/api/directory for the full catalog, or GET https://2s.io/api/search/endpoints?q=<natural-language task> for a ranked match. Per-call price is on each operation as x-payment-info (from $0.001). Batch up to 50 calls behind one payment via POST https://2s.io/api/batch/run.'

      summary: Current US notifiable-disease surveillance from the CDC
      description: 'Current US notifiable-disease surveillance from the CDC NNDSS (National Notifiable Diseases Surveillance System) weekly tables. Returns provisional weekly case counts for ~139 nationally notifiable conditions (e.g. Measles, Pertussis, Mumps, Hepatitis A, Lyme disease, Gonorrhea, West Nile, Dengue) by reporting area and MMWR week, updated weekly. Filter by condition (substring, case-insensitive: "measles" matches "Measles, Indigenous"), location (a reporting area: a US state full name like "California", "New York City", "U.S. Residents", a census region like "Pacific", or a territory), year (MMWR year, 2022 to current), and weeks (most-recent N observations). At least one of condition or location is required. Each record reports the current-week count, the previous-52-week maximum, cumulative cases YTD this MMWR year, and cumulative YTD the prior year for same-week comparison. Public-domain CDC federal data via data.cdc.gov. Use this to see live disease activity and outbreaks that postdate an agent''s training cutoff.'

Each section reports found/error independently — a provider with no Open Payments or Medicare record still returns identity. KYC, healthcare-fraud research, investigative journalism, provider due diligence. Pass npi (required).
