Try the API request Quote first, then run

1. Check the price

Use your TaskFuel API key as TASKFUEL_API_KEY in your terminal or server. Keep it out of browser code. This request checks the price without paying.

This is the exact value estimate request from the test. Adding fields such as property type or comparable count changes the request.

curl --fail-with-body https://app.taskfuel.ai/v1/call \
  -H "Authorization: Bearer $TASKFUEL_API_KEY" \
  -H 'Content-Type: application/json' \
  --data-binary @- <<'TASKFUEL_REQUEST'

  },
  "dryRun": true

2. Run the request

Review amount_usd in the quote. To pay and run, change dryRun to false and add maxAmountUsd with that approved amount inside the same JSON object. Keep the inputs unchanged; this limit applies to one call.

3. Read the result

Read data.price, priceRangeLow and priceRangeHigh, then data.comparables for the listings behind the estimate.

When to use it.

Sizing up a property

Get a value range and the homes behind it.

Ask your agent for an estimate and its comparable listings.

Checking a neighbourhood

Read the market for a zip code.

Medians for sale prices, rents and days on market come with listing counts. Small zip codes have few listings, so a median can swing.

Listing research

List homes for sale in a city.

Our Austin search returned 41 listings on the first page out of 5,572 matches, each with a link to the original listing.

Good Questions.

Do I need a RentCast account?

No. Your agent pays from your TaskFuel balance, so there is nothing else to sign up for.

Is the value estimate an appraisal?

No. It is an automated estimate with a range and comparable listings.

Does it return every listing in a city?

Listings come in pages. Our Austin search returned 41 listings on the first page out of 5,572 matches.

Which areas does it cover?

The tools cover US properties. Our tests used San Antonio, Austin and the 78701 zip code, and coverage varies by area.
