First success

Job: an application developer creates one official Responses document at the dest peel and reads back the public model they sent. Health 200 on this site is not that job.

1. Prerequisites

  • An organization key that starts with sk-sx-. Get API key on this site, or use a key already minted for your organization.
  • Export it as SYLPHX_API_KEY. Do not paste it into a random page. Do not send Binding to the AI peel.
  • First success is this curl. Do not npm install a Sylphx AI SDK as a prerequisite; that package is not required on this path.

2. Call Responses

curl https://api.sylphx.ai/v1/responses \
  -H "Authorization: Bearer $SYLPHX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"openai/gpt-5.5","input":"Hello"}'

Base URL is https://api.sylphx.ai/v1. Envelope is Authorization: Bearer sk-sx-. Model openai/gpt-5.5 is a concrete admitted SKU; the public model on the response stays that SKU.

3. Readback

  • Success: HTTP 2xx Responses object. model is openai/gpt-5.5.
  • invalid_api_key: the bearer is missing, not sk-sx-, or revoked. Fix the key; do not blame the model.
  • model_not_found: that SKU is not admitted. Open the catalog and use a listed id.
  • catalog_unavailable / 503: the catalog door is down. That is not an empty shelf and not a reason to call Chat Completions.
