# Telecom Network APIs: The Shape Of The Answer

**[API Evangelist](https://daily.dev/sources/apievangelist)** · 7 min read · 0 upvotes · 0 comments

## Summary

CAMARA, the Linux Foundation project defining mobile network capabilities as OpenAPI, publishes the shapes for telecom network APIs in the open. SIM Swap returns a boolean 'swapped' and a bounded maxAge integer (1 to 2400, default 240); Number Verification returns a boolean; Quality on Demand uses a three-value enum. Twilio scores 91.6 and leads a 25-member provider cohort, while operators lag, with Orange Business topping carriers at only 65.3. The open gap is QosProfileName, whose real values come from each operator's own QoS Profiles API rather than the standard. GSMA Open Gateway returned a 403 when the author's market work tried to read it.

## Questions this post answers

### What fields does the CAMARA SIM Swap API return and accept?

The CAMARA SIM Swap API has two operations: POST /check, which takes a phoneNumber and a maxAge integer in hours (1 to 2400, default 240) and returns a required boolean called swapped, and POST /retrieve-date, which returns a SimSwapInfo object with a latestSimChange field.

_Teams wiring fraud checks into SIM swap logic can track CAMARA contract details like this on daily.dev._

### What are the predefined QoS profile names in CAMARA Quality on Demand?

CAMARA's QosProfileName field allows predefined values QOS_S, QOS_M, QOS_L, or QOS_E, plus a UUID or a descriptive name, with the full real list coming from each operator's own QoS Profiles API rather than the standard itself. No operator in the catalog publishes that list as a vocabulary or schema yet.

_Developers deciding how to integrate Quality on Demand sessions can follow operator-specific QoS vocabulary gaps on daily.dev._

### Which telecom providers score highest for API readiness in the CAMARA and telecom network API cohort?

Twilio leads with a score of 91.6, followed by Telnyx at 86.1 (with the cohort's highest agent readiness score of 78.6), Infobip at 84.9, Sinch at 71.5, and Vonage at 71.3. Among carriers, Orange Business ranks highest at 65.3, while Verizon, América Movil, MTN Group, AT&T, Telstra, and Kaleyra trail between roughly 43 and 57.

_Developers comparing telecom API providers for agent-ready integrations can track these readiness scores on daily.dev._
