api0.app vs DigitalAPI

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.

DigitalAPI brings APIs managed by different gateways into a shared catalogue for developers, partners, and AI agents. It covers API discovery, governance, documentation, subscriptions, monetisation, and marketplace functions, and connects with Apigee, Kong, AWS Gateway, and Azure APIM. Its developer portal offers API search, access requests, role-based key provisioning, usage tracking, and sandboxes for each environment. The platform can expose APIs as MCP tools, with agent credentials, separate rate limits, and an audit trail; listed clients include Claude, GPT via Responses API tool calls, Gemini, Cursor, Continue, and custom copilots. DigitalAPI also lists analytics, API linting, style guide enforcement, lifecycle controls, and CI/CD integration. Deployment options include self-hosting in a VPC or on-premises, and managed single-tenant hosting.
