api0.app vs Comviva API Marketplace

api0.app combines a no-code API builder with a marketplace for publishing and finding APIs. Its visual builder turns tables or defined fields into typed REST endpoints with request validation and pagination. Supported sources include Postgres, MySQL, SQLite, MongoDB, Google Sheets, CSV uploads and existing REST APIs. Each endpoint has an interactive reference and a downloadable OpenAPI 3.1 specification that updates when the schema changes. Generated APIs are private by default, and marketplace publication is optional. Access features include scoped API keys, secret rotation and rate limits that vary by plan. Publishers can charge per request, offer monthly plans or provide a free tier; the platform meters requests, bills buyers and pays builders monthly after a marketplace fee. The dashboard reports request volume, error rate, p95 latency and revenue by endpoint, including customer-level details. The Free plan costs nothing and includes up to 2 live endpoints and 10,000 requests per month.

Comviva API Marketplace is a cloud-native, microservices-based platform for Communication Service Providers and telecom operators building API ecosystems. It combines CPaaS, NaaS, and Direct Carrier Billing APIs, following GSMA Open Gateway, TM Forum Open API Project, and CAMARA standards. Operators can publish APIs, bundle them with third-party APIs, and launch a branded partner marketplace. The API manager and gateway cover design, publishing, versioning, request routing, and rate limiting. A developer portal provides interactive documentation, testing tools and environments, plus SDKs for Node.js, Python, Java, iOS, Android, and web. Automated workflows handle partner onboarding, contracts, and lifecycle administration. Monetization can use subscriptions, pay-per-use, freemium, dynamic pricing, or revenue sharing. Multi-level access controls, team management, and analytics cover partner programs, API usage, performance, and revenue trends. Supported channels include SMS, voice, WhatsApp, RCS, email, and video. Pricing is on request.
