  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: US Drought Monitor severity for a county (5-digit FIPS) or
      description: US Drought Monitor severity for a county (5-digit FIPS) or state (2-letter code). Returns the weekly percent of area in each drought category — None, D0 (Abnormally Dry), D1 (Moderate), D2 (Severe), D3 (Extreme), D4 (Exceptional) — newest week first, plus the worst category present each week. Keyless, public-domain (NDMC/USDA/NOAA). This is the official metric behind USDA disaster-program eligibility; use for crop-risk, water, and insurance reasoning.
