api0.app vs APIDistributed

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.

APIDistributed is a public, cloud-deployed marketplace for production APIs. It lets one API key reach APIs from multiple providers through a gateway that identifies the provider, checks plans, applies quotas, measures requests, and combines provider charges on one invoice. The homepage lists more than 4,200 APIs spanning AI and machine learning, data, payments, communications, maps, media, and finance. A single Bearer token works across marketplace endpoints. Typed clients are listed for Node, Python, Go, and Rust, with a cURL example. Per-call telemetry reports latency, cost, and status. Pay-as-you-go pricing starts at $0.0002 per call, and the first 100,000 calls each month are free forever; volume discounts apply. Spend caps and per-key budgets are available, with no minimums, seats, or idle fees. API publishing, subscriber billing, and marketplace analytics are supported. The service is in private beta and invites early-access requests.
