This page lists changes to the API and developer docs; see the versioning rules.

2026-10-31

2026-10-28

  • Added the per-call price list: every call's price in dollars, its unit and who may buy it, generated from the price table the API charges by.
  • Changed every call's cost line to its price in dollars, and renamed the page about your balance to Your balance.
  • Added balance_cents, required_cents, cap_cents and consumed_cents (whole cents) to the not-enough-balance and spending-cap errors. balance, required, cap and consumed keep their meaning in dollars and may now carry cents (for example 0.10) (Not enough balance).
  • Added the 403 desk-only error: a call sold only with a Desk, refused before anything is charged.
  • Added the 429 free-call-limit error: an account's free calls for the day are used up.
  • Added the 403 free-calls-locked error: free calls wait until a card is saved.
  • Added cap_scope to the 429 spend-cap-exceeded error: account for the account's daily spending cap, connection for one assistant connection's daily limit.
  • Changed the MCP server to version 1.2.0: assistant tools ask you to confirm any single question that would cost more than $5.00, and accept an optional confirmation value on the repeat (Connect an AI assistant).

2026-10-26

  • Changed the MCP server to version 1.1.0: the existing single-property tools accept either an address or a property identifier, and the optional partial_answer flag on the same terms as the HTTP call (Connect an AI assistant).

2026-10-25

  • Changed the developer docs: a home page, three tabs, search, a five-step quickstart, an example answer on every call, and try-it with your own key (Developer docs)

  • Changed the name the MCP server reports to connected AI clients to Investorlift Data Services, with version 1.0.0 (Connect an AI assistant).

  • Added the API description at a stable address (Download)

  • Added plain-text copies of every guide for AI tools (Docs for AI tools)

2026-10-24

  • Added identifier support: single predict and validate calls now accept exactly one of address or property_id. The existing MCP tools share this additive contract. Identifier picks use the normal price and refund rules; validate remains free. Batch requests are unchanged. Ambiguous-address candidates may include supplied, validated paired coordinates; no extra detail lookup is made for the list (Connect an AI assistant).

  • Added optional coordinates: single-property underwriting answers now optionally include paired numeric latitude and longitude in subject_property and each comps entry. These are the existing supplier coordinates; both are omitted if either is missing or invalid. Latitude is bounded to ±90 and longitude to ±180. Batch and History Call outputs and Credit prices are unchanged (Valuation and comparable sales).

  • Added support for POST /v1/predict to accept an optional partial_answer member: for a property we found but the pricing model does not price, it returns the facts with a null max_allowable_offer and the reasons, charged as an answer. Existing calls are unchanged (Accuracy and limits).

  • Added the figures used to solve the offer: every POST /v1/predict answer's cost_stack now carries assumptions, the figures the maximum allowable offer was solved with. Existing integrations see no change (The maximum allowable offer).

2026-10-23

  • Added the optional X-Customer-Reference request header on every charged call, so resellers can see usage by their own customer. Existing calls are unchanged.

2026-10-22

  • Error responses' documentation gains a plain explanation and next step for every error type.

2026-10-16

2026-10-09

  • Changed property identifiers; identifiers obtained before 9 October 2026 are no longer valid. Look up the address again to get a current identifier (Property and market data).
