Data infrastructure with an API contract
Insight doesn't help if it can't reach the systems where decisions happen. Heroku's Data APIs deliver our intelligence datasets as clean, versioned REST interfaces — the same data behind our dashboards, available to your pricing engines, BI stack, alerting systems and internal tools.
The API is treated as a product: stable schemas with deprecation windows, cursor pagination, idempotent batch endpoints, and documentation with copy-paste examples. Onboarding is designed to take an afternoon, not a quarter.
What's included
The moving parts
Predictable schemas
JSON responses with versioned contracts and documented deprecation policy — breaking changes are announced, never ambushed.
Practical auth
Scoped API keys with environment separation, rotation support and usage visibility per key.
Sane rate limits
Transparent per-tier limits with burst allowance and clear 429 semantics including retry guidance.
Batch & streaming options
Cursor-paginated bulk endpoints for backfills and scheduled warehouse syncs, alongside point queries.
Practice notes
How the discipline is applied
Uptime posture
Redundant delivery layer with status page, change calendar and 99.95% measured availability.
Sandbox first
A sandbox tier with production-shaped starter datasets lets teams prototype before contracting.
Language examples
cURL, Python, TypeScript and Go examples in every endpoint reference.

FAQ
Common questions about data apis
What data is available through the API?
Prices and availability, product and catalog structures, market indicators and selected aggregated intelligence outputs — depending on your program's scope.
Is there a sandbox?
Yes. A sandbox environment with test data mirrors production schemas so integration work can start immediately.
What are the rate limits?
Limits scale by tier, from evaluation keys to enterprise allocations. The documentation lists current numbers; limits are enforced with standard 429 responses and headers.

The `observed_at` vs `ingested_at` distinction in the docs is the kind of detail that tells you the API was designed by people who’ve built models on their own data.

Rate limit headers + retry guidance documented = our infra team approved the evaluation in one meeting. That never happens.

(Team note) Sandbox keys are provisioned instantly on request through the contact form — mark it ‘technical inquiry’ and mention this page.
Can confirm — got one last sprint. Schema docs matched the sandbox responses exactly, which sounds like a low bar and isn’t.
