Plumma SRL is an Italian software house (VAT IT04209450362, REA MO-451932) with its registered office at Via Corsini 21, Fellicarolo, Fanano (Modena) and an operational office at Via Provinciale 175/B, Crespellano, Valsamoggia (Bologna). Its own product, Plumma Connect, is an aggregation gateway in front of mobile network operators: it sells enterprises a single integration point for the operator-held identity, SIM and network-state signals that the GSMA Open Gateway programme exposes, instead of requiring the buyer to onboard operator-by-operator and country-by-country. Plumma states it is a GSMA Open Gateway channel partner and names GSMA, TIM, AWS and WaveMaker among its partners. Its architectural position is the notable part, and it is deliberate. Rather than mirroring the CAMARA one-endpoint-per-capability shape, Plumma Connect publishes a SINGLE OpenAPI 3.1 operation — POST /api on https://connect.plumma.it/services — that takes a phone number in E.164 form plus a list of named commands (sim_swap, kyc_match, age_verification, current_carrier, porting_logs, roaming_intel, churn_tracker, digital_footprint and others), so the CAMARA surface is an implementation detail behind an abstraction layer rather than the developer contract. The company is not, however, standard-averse underneath: its KYC request schema carries the CAMARA KnowYourCustomer Match attribute vocabulary verbatim (in snake_case), and every 4xx/5xx returns an RFC 7807 problem document with a correlation_id. The divergence is at the endpoint shape, not the data model. The product is positioned for fraud prevention and identity verification, with company-stated coverage of 17 live countries across Europe, the Americas, APAC and Africa and 75+ network connections. Documentation, the OpenAPI and a draft-07 request schema are public and ungated, and the JavaScript documentation portal is backed by an unauthenticated JSON content API at connect.ploomma.com that serves 72 documents including the billing guide, SLA, terms and full command reference. Billing is EUR 200/month plus a prepaid wallet charged per served command; published rate limits are 2/5 RPS and 180 commands/day. There is no MCP server, no agent card, no SDKs and no /.well-known documents — the provider marks SDKs and webhooks 'under construction'.
