Evidence-backed parts data for your systems.

A parts database,
not a search box.
Manufacturers share components across hundreds of vehicles. We maintain a structured cross-reference graph with DVLA-verified vehicles and fitment exceptions — so your software can trust the match.
- Equivalence groups linking OEM, aftermarket and superseded numbers
- Source URL and snippet on every cross-reference
- DVLA vehicle lookup from a UK registration mark
- Fitment scoped by segment, year, VIN and gearbox where known

}The trade trick, as data.
Resolve any number
Normalise and match part numbers with confidence scores, then return the equivalence group, cross-references and cited evidence in one response.
Cross-vehicle graph
The same component often fits several vehicles. We store typed links and fitments so your systems can reason about alternatives — not just string matches.
Built for integrators
API keys, usage metering, plan gates and OpenAPI docs. Embed resolve and DVLA lookup in counter software, GMS or overnight catalogue jobs.
From signup to first resolve, in four steps.
- 01
Create an account
Register as an API customer. You get 100 free requests — no card required.
- 02
Create an API key
Generate a key in the dashboard. Copy it once; we store only a hash.
- 03
Call /api/v1/resolve
Send a part number (and optional vehicle segment). Receive group, links and evidence.
- 04
Wire into your stack
Add DVLA lookup and fitment as you grow. Upgrade when you need bulk or higher volume.
A real parts database — not a listing page.
Most parts sites are flat catalogues. Parts Resolve is a structured cross-reference graph with cited evidence and DVLA-verified vehicle data behind every match.
Cross-vehicle graph
Every part number sits in a canonical group with typed links to its OEM, aftermarket and superseded equivalents.
Cited evidence
Every cross-reference is backed by a source URL and the exact line that proved it. Audit any match.
DVLA-verified VRM
We start from the number plate and trust DVLA — not a make/model dropdown filled in by the user.
VIN & gearbox breakpoints
We parse VIN ranges, ZF/DSG/PDK gearbox codes and LHD/RHD out of listings — so the match actually fits.
Fuzzy + phonetic search
Trigram similarity plus soundex with confidence scores. Mistyped numbers still find the right part.
Verified status
Part items move through draft, verified and deprecated — so integrators can prefer trusted rows.
Auto-growing catalogue
A server-side intake parser folds new listings, part numbers and fitments into the graph every day.
Public REST API
Resolve, look up, fitment, bulk — programmatically. Per-key auth, throttling, OpenAPI in your account.
We plugged resolve into the counter — same sensor the factor priced at £86 resolved to a cross-vehicle equivalent we already knew how to source. That graph is the product.
