api0.app

Product: api0.app combines a no-code API builder with a marketplace for publishing and finding APIs.
API generation: The visual builder creates typed REST endpoints with request validation and pagination from tables or defined fields.
Documentation: Endpoints include an interactive reference and a downloadable OpenAPI 3.1 specification that updates with schema changes.
Data sources: The site lists Postgres, MySQL, SQLite, MongoDB, Google Sheets, CSV uploads, and existing REST APIs as supported sources.
Authentication: The platform supports scoped API keys, secret rotation, and rate limits by plan.
Billing: API publishers can set per-call pricing, monthly plans, or a free tier; api0.app meters requests, handles buyer billing, and pays builder earnings monthly after a marketplace fee.
Analytics: The dashboard shows requests, error rate, p95 latency, and revenue per endpoint, including per-customer detail.
Privacy: Generated APIs default to private, and marketplace publishing is optional for each endpoint.
Credential security: The site says database credentials are encrypted at rest and are never shared with marketplace buyers.
Support: The Free plan lists community support, while Builder lists priority support.
Enterprise options: The Enterprise plan lists custom volume and SLA, a VPC or on-prem builder option, SSO, and audit logs.
Intended users: The site describes use for people building APIs from data, selling existing APIs, shipping MVP backends, wrapping legacy systems, and finding or bundling marketplace APIs.
