Quantin API Fundamentals: Authentication, Requests and Pagination

The Quantin API provides a structured way to connect applications, submit work, inspect results, and coordinate approved actions. This guide describes the integration conventions clients should implement before using production resources.

Authentication

Keep credentials on the server side and transmit them only over HTTPS. Use separate credentials for development and production, scope them to the minimum required access, and rotate them regularly. Never embed a secret in browser code, mobile packages, logs, or source control.

Request structure

Send JSON for structured requests and declare the content type. Include a client-generated request identifier for tracing. Mutating operations that may be retried should also include an idempotency key.

curl https://api.example.quantin.ai/v1/runs \
  -H "Authorization: Bearer $QUANTIN_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: unique-client-key" \
  -d '{"workflow_id":"workflow_example","input":{"query":"Summarize current risk"}}'

The hostname and resource names above are illustrative; use the endpoint assigned to your Quantin environment.

Pagination

List endpoints should be consumed with cursor-based pagination. Continue while a next cursor is returned and preserve the requested page size. Do not assume that resource order or page boundaries remain fixed while new records are created.

Error handling

• Authentication errors: verify credential scope and expiry.
• Validation errors: correct the request; do not retry unchanged.
• Rate limits: respect retry guidance and back off.
• Server errors: retry with bounds and the same idempotency key.

Client responsibilities

Set connection and response timeouts, log request identifiers instead of secrets, validate response schemas, and monitor error rates. API access is one part of the workflow’s permission model; downstream actions may still require policy checks or human approval.
