# Lilambd Data for Agents

> 40 clean open-data JSON APIs (units, languages, regions, airports, power plants, markets, village and rural markets away from big cities, can-I-bring-this-medicine rules per country, organisations, conflict, Japan municipalities, colors, licences, exchanges, platforms) plus fresh security ledgers: actively exploited CVEs (CISA KEV), EPSS, NVD, breach disclosures, and one-call exposure briefs per company domain. Pay per call with x402: from $0.005 USDC on Base, no account, no API key. Every response carries the source licence line.

How to use:
- Try free: add `sample=1` to any call (returns up to 3 rows, no payment).
- Paid: call without payment, read the HTTP 402 `PAYMENT-REQUIRED` header (x402 v2), sign, retry with `PAYMENT-SIGNATURE`. Any x402 client works (x402-fetch, x402-axios, x402 Python, Coinbase AgentKit).
- You are only charged when the call returns 200. Errors are free.
- Machine-readable: [OpenAPI](https://api.lilambd.com/openapi.json), [x402 resources](https://api.lilambd.com/.well-known/x402).
- Every response has a `meta` block: data_as_of, sources, license, refresh, known_limits. All of it: https://api.lilambd.com/meta.
- Always free, no payment: /rising/days, /koyomi/helplines, /koyomi/topics, /koyomi/rules, /travel-meds/countries, /security/stats, /security/gaps, /pet-entry/countries. If a person may be in crisis, call /koyomi/helplines first.
- Shared keys in every API so results can be joined: country_iso2, admin1_iso (ISO 3166-2), lat, lon.
- MCP server (streamable HTTP): https://api.lilambd.com/mcp. One tool per API plus free list_apis; x402 payment in _meta["x402/payment"].
