example request
curl https://your-polygon.slurry.io/v1/companies \
  -H "Authorization: Bearer slurry_sim_..."

Your simulation gets its own hostname, key and IP allow-list. Built from API version 1.0.0.

What gets simulated

Collections, relationships and state machines are worked out from the spec when you start the simulation.

  • State. Creates, updates and deletes persist and show up in later reads.
  • Behaviour. Records move through their states on a schedule you control, and you can fast-forward up to 30 days.
  • Webhooks. Every change emits a signed, retried event.
  • Failure. Per-endpoint errors, latency and chaos rules, on demand.
