Your first request, without the setup.

Point the client you already use at SandboxAPIs — any provider in the catalog — and your read code just works against a deep, real-looking data set (olympus-labs), not an empty test account. Read-only and API-identical (every dialect the real provider offers); adoption is a one-line base-URL swap, with no path prefixes and no custom routes.

02 / The guarantees

How it works.

  • Exact mirror. Provider hosts serve provider paths exactly — same JSON, headers, status codes. Your existing client library works unchanged.
  • Read-only. Writes return the provider's error shape with a friendly "this universe is read-only" message naming what was attempted.
  • Coherent. Every reference resolves — a PR's author is a fetchable user, its commits exist with matching SHAs, on every provider alike.
  • Deterministic. Pinned snapshots regenerate byte-identically, so CI never flakes on the data.
  • Cheap to poll. Reads carry an ETag, and a conditional request that returns 304 costs nothing when our CDN answers it from its shared cache.
