GPT Image Hub API Documentos

Todos os endpoints v1, exceto a listagem de modelos, exigem uma chave API no cabeçalho Authorization. A chave bruta é mostrada uma vez no momento da criação; o servidor armazena apenas um hash.

Authorization: Bearer gih_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

O endpoint de modelos retorna IDs de modelo, provedores, proporções suportadas, qualidades suportadas, limites de imagem de referência e créditos por imagem.

curl https://www.gptimagehub.com/api/v1/models

curl https://www.gptimagehub.com/api/v1/images/generations \
  -H "Authorization: Bearer gih_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2",
    "prompt": "A cinematic product photo with premium studio lighting",
    "size": "1024x1024",
    "quality": "high",
    "n": 1
  }'

curl https://www.gptimagehub.com/api/v1/images/generations \
  -H "Authorization: Bearer gih_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -F "model=gpt-image-2" \
  -F "prompt=Use the reference image and render it as a premium studio product shot" \
  -F "size=1024x1024" \
  -F "quality=high" \
  -F "n=1" \
  -F "reference_image=@./reference.png"

O endpoint de créditos retorna o saldo, o tipo de conta e a próxima expiração do crédito para o usuário que possui a chave API.

curl https://www.gptimagehub.com/api/v1/credits \
  -H "Authorization: Bearer gih_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

The image generation endpoint waits for completion by default. Set async to true to receive a generation id immediately and poll /api/v1/generations/:generationId for the result. Credits are charged before provider generation and refunded automatically when the provider fails or returns fewer images than requested.

Use o id retornado pelo endpoint de geração para recuperar seu log salvo e imagem URLs. As chaves API só podem ler gerações pertencentes ao mesmo usuário.
