Apibara Vehicle Auction Data

Search auction vehicles

search_auction_vehicles

Read-onlyIdempotent

Use for broad inventory discovery, filtering and incremental synchronization across supported Copart and IAA / IAAI records. For one known VIN or lot use get_vehicle; for retained auction appearances use get_vehicle_history.

Input Schema

Name	Required	Description
`s`	No	Search by VIN, lot number or vehicle title/model text.
`zip`	No	ZIP/postal code used with radius for supported proximity search.
`make`	No	Make filter for GET /vehicles.
`type`	No	Vehicle type filter for GET /vehicles.
`color`	No	Color filter for GET /vehicles.
`model`	No	Model filter for GET /vehicles.
`units`	No	Geographic distance unit system: mi or km. Odometer filter boundaries are always miles.
`cursor`	No	Opaque pagination cursor returned by the API. Send next_cursor back unchanged; do not decode or synthesize it.
`damage`	No	Primary damage category filter.
`radius`	No	Search radius around zip, interpreted using the selected units.
`series`	No	Series / model family filter for GET /vehicles.
`has_key`	No	Key-availability filter using the documented values No, All or With.
`year_to`	No	Year to filter for GET /vehicles.
`per_page`	No	Requested page size. Effective maximum is subscription-plan dependent; common public plan limits are 20, 30 or 40 and custom plans may differ.
`platform`	No	Readable auction-source selector: copart or iaai. Omit for combined supported sources.
`run_cond`	No	Normalized run-condition filter.
`upcoming`	No	Upcoming selector: all=no upcoming restriction, only=upcoming eligible lots only, without=exclude upcoming lots.
`body_type`	No	Deprecated compatibility alias for body_style. A string or array is accepted; prefer body_style for new integrations.
`cylinders`	No	Cylinders filter for GET /vehicles.
`fuel_type`	No	Fuel type filter for GET /vehicles.
`loc_state`	No	Auction location state or region, for example FL.
`price_max`	No	Price max filter for GET /vehicles.
`price_min`	No	Price min filter for GET /vehicles.
`year_from`	No	Year from filter for GET /vehicles.
`body_style`	No	Filter by vehicle_specs.body_style. A string or array is accepted; multiple values are OR-ed. IAAI uses VehicleClass and Copart uses the source-backed Body Style field.
`drive_type`	No	Drive type filter for GET /vehicles.
`generation`	No	Generation filter for GET /vehicles.
`lot_status`	No	Auction mode filter: All, Timed or Buy Now.
`today_only`	No	When true, restrict results to the endpoint current-day auction logic.
`vin_prefix`	No	VIN prefix(es) filter for GET /vehicles.
`engine_type`	No	Engine type filter for GET /vehicles.
`facility_id`	No	Auction facility identifier used to restrict results to one supported facility.

`office_name`	No	Auction office or branch name filter.
`seller_type`	No	Normalized seller type: dealer, finance, insurance or non_insurance.
`auction_type`	No	Numeric compatibility source selector: 0=all, 1=Copart, 2=IAAI. If both auction_type and platform are supplied, auction_type takes precedence; prefer platform for new integrations.
`transmission`	No	Transmission filter for GET /vehicles.
`generation_id`	No	Generation ID filter for GET /vehicles.
`include_total`	No	Include exact total filter for GET /vehicles.
`odometer_from`	No	Odometer from (miles) filter for GET /vehicles.
`engine_size_to`	No	Engine size to filter for GET /vehicles.
`lot_sub_status`	No	Normalized auction state: Open for active/open lots, Live for currently live supported lots, Ended for closed/ended lots.
`auction_date_to`	No	End auction date in YYYY-MM-DD format.
`engine_size_from`	No	Engine size from filter for GET /vehicles.
`auction_date_from`	No	Start auction date in YYYY-MM-DD format.
`has_shipping_price`	No	When true, return only vehicles with supported shipping-price data.
`sale_document_type`	No	Sale/title document type filter; values are source-backed and can vary.
`auction_date_pending`	No	Auction date pending filter for GET /vehicles.
`sale_document_pending`	No	When true, restrict results to records with a pending sale document state when supported.
`updated_within_minutes`	No	Incremental-sync window. Return records whose updated_at changed within this many minutes; supported range is 1..525600. Use with cursor pagination and an overlap window.

A4.2/5.0

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly, idempotent, non-destructive and open-world, so the safety profile is fully covered. The description adds useful scope context (combined Copart/IAAI sources, incremental-sync use case) but says nothing about result shape, cost, or the subscription-dependent page-size behavior that meaningfully affects calling strategy. Adequate but thin for a 50-parameter search endpoint.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero filler, positive use case front-loaded before the sibling redirects. Every clause earns its place and the disambiguation is placed last where it is most actionable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists and the input schema is fully documented, so return values and parameter meaning are covered elsewhere. What is missing is guidance on how the 50 filters compose (conjunctive vs. OR behavior) and how paging interacts with updated_within_minutes for sync loops, which is the one gap an agent could stumble on.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, including enum values, units, cursor semantics, deprecation notes for body_type, and platform vs auction_type precedence, so the schema carries the full load. The description contributes no filter semantics of its own, which makes baseline 3 correct.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific action (broad inventory discovery, filtering, incremental synchronization) over a specific resource (auction vehicles from Copart and IAA/IAAI). It explicitly demarcates itself from get_vehicle and get_vehicle_history, so an agent can route without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Names two alternatives with the exact condition that selects each: one known VIN or lot -> get_vehicle; retained auction appearances -> get_vehicle_history. The implicit remainder (broad/filtered/multi-record sweeps) is the positive case for this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
