RS Performance Sp. z o.o. is a single-location automotive diagnostics and repair workshop at Al. Grunwaldzka 303B in Gdańsk, Poland (the Premio Ring site, rebranded 2021-09-14), serving Gdańsk, Sopot, Gdynia and the Tricity with 19 workshop services from computer diagnostics, DPF/AdBlue, turbo and gearbox work to tyre storage and B2B fleet service. What makes it an API provider is the machine-readable layer it has built over its knowledge base: an anonymous A2A agent (nine skills, JSON-RPC 2.0 and HTTP+JSON on rsperformance.online, agent card at the canonical well-known path), a remote FastMCP server "Diagnosta RS" with 14 tools over a Qdrant vector store of services, FAQ, repair reports and 12,000+ OBD-II fault codes, and a three-operation OpenAPI 3.1 "AI Gateway" on ai.rsperformance.online for answer-first semantic search, freshness and answer routing — plus llms.txt, security.txt, an ai-plugin manifest, JSON/Atom change feeds and a DTC JSON feed. Every surface is free and unauthenticated under a fair-use, attribution-required policy.
RS Performance publishes 4 API contracts indexed on the APIs.io network, including Search API, .well Known API, and 2 more. Tagged areas include Automotive, Auto Repair, Vehicle Diagnostics, OBD-II, and Fault Codes.
RS Performance’s developer surface includes documentation, getting-started guide, API reference, engineering blog, support, FAQ, authentication, and 33 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
