Extract video data with Go

Extract video data with Go: a net/http example that submits an extraction job with an idempotency key, so a retried request never runs twice.

The code

type Column struct {
    Name        string `json:"name"`
    Type        string `json:"type"`
    Description string `json:"description,omitempty"`
}
 
body, _ := json.Marshal(map[string]any{
    "videos":   []string{url},
    "multiple": true,
    "schema": []Column{{
        Name:        "claim",
        Type:        "string",
        Description: "A factual claim the host states out loud",
    }},
})
 
req, _ := http.NewRequest("POST",
    "https://api.tubeextract.dev/v1",
    bytes.NewReader(body))
 
req.Header.Set("X-API-Key", os.Getenv("TUBEEXTRACT_KEY"))
req.Header.Set("Content-Type", "application/json")
req.Header.Set("Idempotency-Key", runID+":"+videoID)
 
resp, err := http.DefaultClient.Do(req)

Notes

The idempotency key is derived from the run and the video rather than generated fresh, so retrying after a timeout returns the original job instead of queueing the video twice. See retries and idempotency.
