#Real-world use cases

#E-commerce localization

Challenge: Translate product descriptions to 10+ languages
Solution: Use translate with variants for regional preferences

// Translate to Brazilian Portuguese (variant ID 7)
POST /v1/text/translate
{
  "text": "Premium leather wallet with RFID protection",
  "target_language": {"type":"variant","id":7},
  "context": "E-commerce product, professional tone"
}

#Customer support automation

Challenge: Handle multilingual support tickets
Solution: detect-language → translate with source_languages

// 1. Detect languages in ticket
POST /v1/text/detect-language {"text":"Hello! Je voudrais aide..."}
// Returns: languages [21, 26]

// 2. Translate with source hint
POST /v1/text/translate {
  "text":"Hello! Je voudrais aide avec mon compte.",
  "target_language":{"type":"language","id":21},
  "source_languages":[
    {"type":"language","id":21},
    {"type":"language","id":26}
  ],
  "context":"Customer support, polite"
}

// 3. Summarize for quick triage
POST /v1/text/summarize {
  "text":"...",
  "max_sentences":2,
  "context":"Support ticket summary, highlight urgency"
}

#Content platform with voice preferences

Challenge: User-generated content needs correction while maintaining voice
Solution: Use context to preserve gender/tone

// Correct while maintaining feminine voice
POST /v1/text/correct {
  "text":"Their going too the store",
  "context":"Feminine voice, casual tone"
}
// → "She's going to the store"

// Rephrase with masculine, formal context
POST /v1/text/rephrase {
  "text":"I wanna say that...",
  "context":"Masculine, formal business communication"
}
// → "I would like to state that..."

#Best practices

Cache language lists: /languages returns config data — cache for 24h or longer
Use language IDs consistently: Document which IDs your app uses (e.g., English=21, Spanish=87)
Leverage variants: Use American English (ID 1) vs British (ID 2) for regional accuracy
Keep contexts concise: 500 char limit — focus on key preferences like "Formal medical" not lengthy descriptions
Combine operations: detect → translate → correct for multilingual content pipelines
Handle rate limits: Implement exponential backoff for 429 responses
Monitor response times: Use response_time_ms to track API performance

#Technical architecture

Text API uses a config-based architecture with zero database dependencies:

Languages: Static config file with 105 languages + 23 variants
Contexts: Simple text parameters (no database storage)
Logging: Handled by ApiBase (existing api_requests tables)
Performance: ~5-10ms for /languages, no database queries for language lookups

Ofte stillede spørgsmål

Vi understøtter 50+ sprog til oversættelse, og sprogregistrering fungerer for alle større verdenssprog inklusive kyrillisk, latinsk, asiatisk og mellemøstlig skrift.

Vores AI-drevne oversættelse bevarer kontekst og nuancer og opnår professionel kvalitet. For kritiske dokumenter anbefaler vi menneskelig gennemgang.

Kontekster lader dig definere præferencer som tone (formel/uformel), brancheterminologi og stilguider, der gælder for alle dine tekstbehandlingsforespørgsler.

Ja! Vi bevarer afsnit, linjeskift og listestrukturer. Kompleks formatering som tabeller kan kræve særlig håndtering.

Ja. Hver forespørgsel, selv dem der resulterer i fejl, forbruger kreditter. Dine kreditter er bundet til antallet af forespørgsler, uanset succes eller fejl. Hvis fejlen tydeligt skyldes et platformproblem på vores side, gendanner vi de berørte kreditter (ingen kontant refusion).

Kontakt os på [email protected]. Vi tager feedback alvorligt—hvis din fejlrapport eller funktionsanmodning er meningsfuld, kan vi rette eller forbedre API'et hurtigt og give dig 50 gratis kreditter som tak.

Det afhænger af API'et og nogle gange endda af endpointet. Nogle endpoints bruger data fra eksterne kilder, som kan have strengere grænser. Vi håndhæver også grænser for at forhindre misbrug og holde vores platform stabil. Se dokumentationen for den specifikke hastighedsgrænse for hvert endpoint.

Vi opererer med et kreditsystem. Kreditter er forudbetalte, ikke-refunderbare enheder, du bruger på API-kald og værktøjer. Kreditter forbruges FIFO (ældste først) og er gyldige i 12 måneder fra købsdatoen. Dashboardet viser hver købsdato og dens udløb.

Ja. Alle købte kreditter (inklusive brøkdele) er gyldige i 12 måneder fra købet. Ubrugte kreditter udløber automatisk og slettes permanent ved udgangen af gyldighedsperioden. Udløbne kreditter kan ikke gendannes eller konverteres til kontanter eller anden værdi. Overgangsregel: kreditter købt før 22. sep. 2025 behandles som købt den 22. sep. 2025 og udløber den 22. sep. 2026 (medmindre en tidligere udløbsdato var angivet ved købet).

Ja—inden for deres gyldighedsperiode. Ubrugte kreditter forbliver tilgængelige og overføres fra måned til måned, indtil de udløber 12 måneder efter købet.

Kreditter er ikke-refunderbare. Køb kun det, du har brug for—du kan altid fylde op senere. Hvis en platformfejl forårsager en mislykket opkrævning, kan vi gendanne de berørte kreditter efter undersøgelse. Ingen kontant refusion.

Priser er angivet i kreditter, ikke dollars. Hvert endpoint har sin egen pris—se mærket "Kreditter / forespørgsel" ovenfor. Du ved altid præcis, hvad du bruger.
