# FMCSA Carrier Intelligence > Pay-per-call US motor carrier safety, authority and identity-linkage data built from FMCSA public records, for AI agents. MCP and A2A endpoints; paid in USDC on Solana via x402 v2; no account or API key. Charged only when a call returns records. Operated by 4SAKE Agent Co. Not affiliated with or endorsed by FMCSA or the US DOT. The data describes regulated motor carriers as business entities and is not a consumer report. It must not be used as a factor in any individual's eligibility for credit, insurance, employment or housing (see Terms). ## Docs - [For agents](https://kmcto.github.io/fmcsa-carrier-intelligence/for-agents/): endpoints, x402 payment flow, prices, billable-event rule, rate limits, error codes, examples - [Skill](https://kmcto.github.io/fmcsa-carrier-intelligence/SKILL.md): when and how to use each tool - [Terms of Service](https://kmcto.github.io/fmcsa-carrier-intelligence/terms/) - [Privacy Policy](https://kmcto.github.io/fmcsa-carrier-intelligence/privacy/) ## Endpoints - MCP (streamable HTTP): https://fmcsa-mcp-843680657471.us-central1.run.app/mcp - A2A Agent Card: https://fmcsa-a2a-843680657471.us-central1.run.app/.well-known/agent-card.json
