api record

Freight intelligence tools from FreightFA, an independent rate-benchmark service (not a broker or carrier). For a lane given as places, call recommend_mode to rank modes and get the distance, then estimate_truckload_rate, estimate_ltl_rate, estimate_rail_rate, estimate_intermodal_rate, or estimate_barge_rate for a price; estimates and ask_freight_analyst questions count toward the user's monthly FreightFA allowance, the other tools don't. Market: get_market_snapshot (today's national truck rates and diesel), get_market_outlook (next week's truck forecast), get_rail_market_outlook,…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

get_market_snapshot open 2h ago
Today's U.S. national truckload rates per mile for dry van, reefer, and flatbed (all-in including fuel, with linehaul and fuel split), FreightFA's live-quote index, and EIA diesel, each with its source week and the change over the last 7 days. Use it for 'what are truck rates right now' questions; cite it as FreightFA with the as-of date. Does not count toward the estimate allowance.

estimate_intermodal_rate unknown never probed

Estimate a door-to-door domestic intermodal (rail + truck) rate between two U.S. places: drayage to the nearest Class I ramp, the rail line-haul, and drayage from the destination ramp, with the ramps used. Says when a lane has no intermodal service. Each call counts as one estimate toward the account's monthly FreightFA allowance.

estimate_rail_rate unknown never probed

Estimate a Class I carload rail freight rate for a commodity, distance, and weight. Pass origin and destination to check for active freight track near both ends (USDOT rail network): rail_access names the railroads nearby, and a lane with no track within 50 miles of an end returns available: false with the reason instead of a price. Don't quote rail on such a lane. Returns a directional benchmark for planning. Each call counts as one estimate toward the account's monthly FreightFA allowance.

recommend_mode unknown never probed

Rank the freight modes (dry van, reefer, flatbed, intermodal, rail, barge, dump truck) for a shipment between two U.S. places, with the reasons for each, and return the lane distance in miles. Use it first when you only have city names or ZIPs, then pass the distance to an estimate_* tool for a price. International lanes return the ocean/air routing instead. Does not count toward the estimate allowance.

estimate_network_cost unknown never probed

Price a supply chain of up to 10 legs (factory to port to warehouse to store, domestic or international) and total it, with each leg's mode, cost, and transit time. Saved to the user's Network Builder. Full costs are included with FreightFA Desk; other accounts can spend a one-time trial run by setting use_trial_run to true, otherwise legs come back without costs.

calculate_margin unknown 2h ago

Margin on a load from the buy rate (carrier cost) and sell rate (what the shipper pays): margin in dollars and percent of sell, the per-mile spread when miles are given, and the sell price needed to hit a target margin. Pure arithmetic; does not count toward the allowance.

estimate_barge_rate unknown 2h ago

Estimate an inland waterway barge freight rate for a bulk commodity, origin, destination, distance, and weight, from USDA's weekly downbound grain barge rates. Only priced when both ends are Mississippi/Illinois/Ohio River ports, the lane runs downriver, and the shipment is at least one barge-load (~1,500 short tons, 3,000,000 lb); otherwise returns available: false with the reason. Priced on river miles. Returns a directional benchmark for planning. Each call counts as one estimate toward the account's monthly FreightFA allowance.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 11203c1426b0011b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/11203c1426b0011b/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/11203c1426b0011b/badge.svg)](https://brick.blue/agent/11203c1426b0011b?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
