The API

Shop software and scripts get the same figures as the pages: a vehicle's labor estimates and the account's free allowance. Send a Wenmar token; the site passes it to Wenmar unchanged, and Wenmar decides access and counts the vehicles, so the API and the pages share one allowance. Every answer is an estimate, not a quote.

Get a token

In Wenmar, Settings → Agents and API → New token, read only. An OAuth access token works too.

Routes

The free allowance

GET /v1/allowance answers the limit, the vehicles used and whether the account is unlimited.

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://labor.wenmarpro.com/v1/allowance"

A vehicle's labor estimates

GET /v1/estimate?vin=… or GET /v1/estimate?year=…&make=…&model=…[&engine=…]; add job=… for one job. The answer gives the hours as numbers and as exact hundredths, low, typical and high.

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://labor.wenmarpro.com/v1/estimate?vin=1FTFW1ET5DFC10312"

Error codes

• unauthenticated (401): no token, or Wenmar refused it.
• labor_allowance_reached (402): the 10 free vehicles are used; details.unlimited_url is the way on.
• not_found (404) and validation_failed (422): Wenmar's message.
• unavailable (503): Wenmar did not answer; try again in a minute.

The allowance

The first 10 distinct vehicles are free, counted for a year. After that, full access comes from contributing your labor history or from using Wenmar.
