Automate PlanetBids with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• New bid opportunities from every agency you work with

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  For each agency portal you name, get the bid opportunities that are open.

  Step 2

  Keep the projects that were not there on the last run.

  Step 3

  Email you the list, one section per agency, with title and due date.

• New addenda on the projects you are bidding

  Build this

  Starts

  Every weekday at 8:00

  Step 1

  For each project on your list, read its documents and addenda.

  Step 2

  Keep the addenda your company has not acknowledged.

  Step 3

  Post each one, with agency, project and due date, to your webhook.

• eBids not yet submitted before they close

  Build this

  Starts

  Every weekday at 15:00

  Step 1

  For each project on your list, check the eBid status next to Place eBid.

  Step 2

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get bid opportunities from an agency” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "vendors.planetbids.com/get_bid_opportunities",
    "input": {
      "agency_portal": "City of Acme",
      "keyword": "paving",
      "status": "open"
    }
  }'

{
  "status": "completed",
  "data": {
    "agency_portal": "City of Acme",
    "projects": [
      {
        "project_title": "Residential Street Paving, Phase 4",
        "due_date": "2026-12-03T14:00:00-08:00",
        "status": "open",
        "accepts_ebids": true
      },
      {
        "project_title": "Northwind Park Parking Lot Resurfacing",
        "due_date": "2026-11-20T10:00:00-08:00",
        "status": "open",
        "accepts_ebids": true
      }
    ],
    "count": 2
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

PlanetBids’s own options

PlanetBids does not document an API for vendors. Each agency's Vendor Portal is free: you register with that agency, find its bids, download documents and place eBids in the browser, and registered vendors get its bid alert emails. VendorLine, a paid annual subscription, gathers bids from many agencies and sends a daily bid notification; its FAQ lists no CRM integration, only manual export.

Signing in to PlanetBids

An agency's Vendor Portal signs you in with your email address and password, and the “Need password help?” link sends a reset email. Once you are registered with several agencies, one login moves between their portals from the Agency List. With Fous you sign in once through PlanetBids' own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

One registration per agency

Each agency has its own registration form, and you register with each one separately, free. After that, the Agency List switches between your agencies' portals with one login, so a method takes the agency as an input.

Private documents need prospective bidder status

Documents marked with an asterisk open only after you sign in and become a Prospective Bidder. PlanetBids records each document you download, and some projects require the private documents downloaded before you can bid.

Only Submitted eBids count

Draft, Withdrawn and Invalidated eBids are not considered submitted and are not eligible for award. The transfer must finish before the due time, and a submitted eBid is confirmed on screen and by email.

Signing bids takes a PIN

To submit an eBid, a user must check “I am authorized to sign bids and offers” in the vendor profile. The PIN is emailed to the primary contact only.
