Registration Ultra Resolver

Image in. Aircraft out.

One API turns an aircraft photo into a confident registration — even when the tail isn’t readable — plus identity, valuation, and embeds. Backed by the Tail aircraft graph. Try every endpoint right here, free, no signup.

Instant. No approval, no credit card. ~10 seconds.

Built for agents & GPTs

Plug it into your model

Every endpoint is a clean JSON tool. Import the OpenAPI spec as a custom-GPT Action, or register them as function-calling tools in your own app. For “what aircraft is this photo?”, hand the resolver an image_url — the agent-friendly path. Text endpoints work with zero friction.

Four APIs, one key

One key works across everything. Photos flow keyless; programmatic use needs a free key.

Ultra Resolve

A photo in, a confident aircraft registration out — even when the tail isn’t readable. Returns ranked candidates, each with a confidence score and the verified record behind it. Add any context you have (a partial tail, the airport, the date) to sharpen the result.

Parameter	Type	Description
image	file	Multipart upload of the aircraft photo.
image_url	string	Alternative to a file — a URL to the image. Best path for agents/GPTs.
consent	boolean	Required for uploads — grants a license to process the image.
context.registration_hint	string?	A partial or uncertain tail number, any format.
context.airport	string?	ICAO/IATA where the photo was taken.
context.photo_date	date?	When the photo was taken (ISO).
context.make / model	string?	Your best guess at the type.

GET/v1/identityFree · key for volume

Identity

A registration, serial, or free-text type name → a verified aircraft record from the graph: normalized make/model, category, registry status, year, and our licensed photos with attribution. We return truth from the graph, not an LLM guess.

Parameter	Type	Description
registration	string	e.g. N526JS — exact tail lookup.
serial	string	Airframe serial number.
free_text	string	Fuzzy type, e.g. “Grob 103 Twin II”.
country	string?	Narrow by registry country.

POST/v1/valuationFree · attribution required

Valuation

An aircraft → a value estimate with a range, condition, and the lowest active market ask, drawn from the Tail comps graph. Free to use — you just display a “Powered by Tailestimate” attribution wherever the number appears.

Parameter	Type	Description
registration	string	Preferred — values that specific airframe.
model	string	Fallback — a representative estimate for the model.
year	int?	Narrow the model estimate by year.
