Freight Waves
FreightWaves is a supply-chain, logistics, and transportation news and market- intelligence company based in Chattanooga, TN, and backed by 8vc. Its SONAR platform delivers freight-market data — rate indexes, tender volumes and rejection indexes, capacity and pricing signals — by market, lane, and national geography over a REST API at api.freightwaves.com. Access uses a bearer token obtained from the Credential authenticate endpoint (valid one year); data calls are billable while lookup calls (indexes, qualifiers, levels, lanes, zip3, latest) are free, and a global 100 requests/minute rate limit applies. FreightWaves also operates a hosted, OAuth-protected MCP server (api.freightwaves.com/mcp, scope mcp:read) exposing SONAR data to agents.
Freight Waves publishes 1 API on the APIs.io network: SONAR API. Tagged areas include Company, Freight, Logistics, Supply Chain, and Transportation.
Freight Waves’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, pricing, and 22 more developer resources.
