Turn your database into a product.
Connect SQL Server, PostgreSQL, or MySQL. Build queries and publish them as documented REST endpoints. Share or monetize them in a community marketplace — with no infrastructure to run.
Free sandbox in 60 seconds · No credit card
Built for residents, HOAs, communities, and trusted partners
From database to documented API in three steps.
Connect
Point DAPI at your SQL Server, PostgreSQL, or MySQL database with read-only credentials — encrypted at rest, never shared.
Build
Turn any query into a REST endpoint. Map and rename fields, mask sensitive columns, and set rate limits per consumer.
Publish
Go public, private, or invite-only. Docs, API keys, and usage quotas are generated for you the moment you publish.
Everything between your data and your developers.
One workspace to connect, build, secure, publish, and measure your APIs.
Connection manager
SQL Server, PostgreSQL, and MySQL connections with health checks and read-only enforcement.
SQL query builder
Write, test, and version queries safely before they ever serve a single request.
Endpoint builder
Map columns to clean JSON fields, rename outputs, and mask anything sensitive.
Auto-generated docs
Every API ships with reference docs, an OpenAPI spec, and a Postman-ready collection.
Marketplace listings
List APIs publicly or invite-only. Every public listing is reviewed before going live.
Keys & security
Sandbox and live keys, per-key rate limits, monthly quotas, and AES-256 encrypted credentials.
Analytics
Requests, latency, error rates, and your top consumers — per API and per key.
Webhooks & automation
Signed webhook deliveries with automatic retries, ready for your favorite automation tools.
Your first call in under a minute.

Real data, finally shareable.
Our violation and ARC data lived in a SQL Server nobody could touch. Now residents and our management partner read it through one documented API — and the board finally trusts the numbers.
I published our crew availability as an API in an afternoon. Two property managers subscribed the same week, and the webhook into our scheduler means zero double-bookings.
Sandbox key to working integration in under ten minutes. The OpenAPI spec and the consistent data/meta envelope made it feel like a product team of fifty built it.
Questions, answered.
Which databases does DAPI support?
SQL Server, PostgreSQL, and MySQL today. You connect with your own credentials — DAPI never copies or hosts your data, it queries your database on demand and returns clean JSON.
Is my database safe? What can DAPI actually run?
Connections are read-only by default and credentials are encrypted with AES-256-GCM at rest. DAPI enforces single-statement SQL, so an endpoint can only ever run the query you saved — no arbitrary writes, no chained statements. Sensitive fields can be masked (redacted, last-4, or hashed) before they leave the gateway.
How do sandbox vs. production keys work?
Every account gets a free sandbox key instantly — use it to explore any marketplace API with test-tier limits. Production keys are approval-gated: the API publisher (and, for public listings, our review team) approves access, then your live key carries its own rate limits and monthly quota.
Who can list an API on the marketplace?
Anyone on a Pro or Enterprise plan — HOAs, property managers, home-service businesses, community orgs, or independent developers. Public listings go through a short review for quality and data-safety before they appear in the marketplace.
Can I keep an API private or invite-only?
Yes. Each API can be public, private (only you and your team), or invite-only — you choose exactly which residents, partners, or organizations can request a key, and you can revoke access at any time.
How do Zapier, Make, and n8n connect?
Two ways: call any DAPI endpoint from an HTTP step using your API key, or point DAPI webhooks at a Zapier/Make/n8n trigger URL. Webhook deliveries are signed and automatically retried, so your automations stay in sync.
