Start with /for-ai-agents.md for the rules an agent must follow. > The API is at https://agent.lanesurf.com and the MCP server at https://agent.lanesurf.com/mcp. Lanesurf doesn't send webhooks: poll. > Limits: /rate-limits.md. Keys: /api-keys.md. Safe retries: /idempotency.md. Every route on one page: /api-reference.md. > Always confirm with the person before accepting a carrier offer or bidding on a load. Never reveal an API key, and never show broker contact details to a carrier. > The full contract is at /openapi.yaml. > Sign up with POST /v1/signup (carrier or broker, a work email, an MC and/or DOT number), then POST /v1/signup/{signup_id}/verify. Follow next_step on every signup answer. # Accept an offer > Pick this carrier. Lanesurf stops looking. Records that the rep picks this carrier. Lanesurf takes the load off the market (it goes inactive) and stops looking. The load becomes `covered` with `covered_by: lanesurf` and `winner` set. Lanesurf does **not** contact the carrier or send a rate confirmation: the broker reaches out to the winner (`contact_email` / `contact_phone` on `winner`) to book, and sends the rate confirmation from their own TMS. Lanesurf also emails the brokerage's reps (the load's CC list, else the brokerage's CC list, plus the rep who posted it) the carrier's details. Confirm with the person before calling this. * Accepting the same offer again is safe: you get the same answer. Send the offer's `rate` that the person agreed to. If the carrier changed its rate since, nothing is accepted and you get `409 offer_changed` with `current_rate`: ask the person again. * `409 already_covered`: another offer was already accepted, or the load was marked covered (`POST /v1/loads/{id}/covered`) or deleted. A load can't be both accepted and marked covered. * `409 offer_changed`: the offer's rate isn't the one sent (the carrier changed it, or the rate sent was wrong); `current_rate` has it and `error` names both. Nothing was accepted. * A declined offer can still be accepted later. An offer on a paused load can be accepted too; the load becomes covered. Reopening a covered load puts it back to sourcing, even if it was paused before. * `400 invalid_request`: no `rate` was sent, or this carrier hasn't named a usable rate yet. ## OpenAPI ````yaml /openapi.yaml post /v1/loads/{id}/offers/{session_id}/accept openapi: 3.1.0 info: title: Lanesurf Agent API version: 0.4.0 summary: >- Let any AI agent get a freight load covered, or get a truck loaded, through Lanesurf. description: > Lanesurf finds carriers for freight loads by email, phone and text, and negotiates the rate. This API lets AI agents (Claude, ChatGPT, Grok, Cursor and others) and scripts use Lanesurf directly. There are two kinds of caller: - **Broker agents** ("cover this load for me"): post a load as JSON fields, send any fields Lanesurf says are missing, then read carrier offers and pick one. Paths under `/v1/loads`. - **Carrier / dispatcher agents** ("find a load for my truck"): post trucks and lanes, search loads, and bid on a load. Paths under `/v1/carrier`. Every request (except signup and `/health`) uses `Authorization: Bearer ls_live_...`. - A **broker key** belongs to one rep at a brokerage. It reaches only loads that brokerage posted through this API, whichever of the brokerage's reps posted them. It never reaches loads that came from the brokerage's TMS or from other brokerages. - A **carrier key** belongs to one carrier signup. Its trucks, lanes and bids are its own; no other key sees them. Load search covers active loads from Lanesurf brokers that show their loads to carriers' agents, without broker identity or contacts. Only **verified** carrier keys can read loads (search, one load, matches) and bid; keys whose carrier account is under review (`needs_review`) get `403 verification_required` there. Anyone can get a key with `POST /v1/signup` (carrier or broker, a work email, an MC and/or DOT number) and `POST /v1/signup/{signup_id}/verify`. Every signup reply has `next_step`, which tells an agent what to do next. A brokerage that signs up starts with carrier outreach off until Lanesurf reviews it. Broker keys can't call `/v1/carrier/*` and carrier keys can't call `/v1/loads/*` (`403 wrong_role`). Every response has an `X-Request-Id` header, and every error body a `request_id`. Send your own `X-Request-Id` (8-64 letters, digits, `.`, `_` or `-`) to have it used instead. Quote it to Lanesurf support when something fails. Every authenticated `/v1` route is limited to 120 requests per minute per API key, counted on each Lanesurf server (treat it as the most to send). Over the limit you get `429 rate_limited` with a `Retry-After` header. **Lists.** Your loads (`GET /v1/loads`) come a page at a time: `limit` (1 to 100, default 25), then send `next_cursor` back as `cursor` until it is `null`. Load search (`GET /v1/carrier/loads/search`) and truck matches (`GET /v1/carrier/trucks/{truck_id}/matches`) take `limit` (1 to 100, default 25) and return the closest loads first (see each route), with `total` = the number returned. There is no `offset` or cursor: to see other loads, narrow or change the search. The other lists have no paging and return the newest items up to a cap: trucks 200, lanes 500, bids 200, and a carrier's outreach 50 loads (from the last 30 days). A load's outreach lists every carrier on that load. Lanesurf doesn't send webhooks: poll a load (`GET /v1/loads/{id}`) or your bids (`GET /v1/carrier/bids`) every few minutes.
