Developer API

Isama ang lokalisasyon ng Addavox sa iyong daloy ng trabaho. Piliin ang Video Dubbing API para sa kumpletong lokalisasyon ng video na may kasamang timing, QA, mga subtitle, at kumpletong access sa Review Editor sa pamamagitan ng mga magic link. Maaari ka ring pumili ng alinman sa mga indibidwal na service API para sa iba pang mga gawain, tulad ng pagsasalaysay ng isang libro o pagsasalin at pagsasalaysay ng isang libro nang sabay-sabay.

API Mga Susi

Ang mga API key ay pagmamay-ari ng isang Addavox account. Gumawa ng isa gamit ang button na Simulan ang pag-localize sa itaas, pagkatapos ay bumuo ng isang key sa app — bawat tawag ay sisingilin sa account na iyon.

Ang mga indibidwal na serbisyo API ay binabayaran mula sa iyong credit balance, na iyong ilalagay sa top-up at pamamahalaan sa iyong Addavox account. Ang buong video localization ay ang eksepsiyon: ginagamit nito ang parehong presyo gaya ng planong pipiliin mo sa Mga Plano at Pagpepresyo — kasama na ang mga minuto ng iyong plano, pagkatapos ay ang overage sa rate ng plano.

Pahintulot at Awtorisasyon

Dapat kasama sa lahat ng kahilingan API ang isang consent object at isang top-level mode field. Kapag pinagsama-sama, lilikha ang mga ito ng isang per-job attestation record na nagpapatunay na hawak mo ang mga kinakailangang karapatan at mga pahintulot ng tagapagsalita.

Ang field ng mode ang tumutukoy sa voice synthesis: ang "voice_matched" ay gumagamit ng speaker voice cloning, ang "standard" ay gumagamit ng synthetic TTS. Parehong presyo ang parehong mode — ang pagpili ay batay lamang sa pahintulot.

Patlang	Uri	Kinakailangan	Paglalarawan
mode	string	Pinakamataas na antas	`voice_matched` o `standard`
speaker_consent_obtained	boolean	voice_matched lamang	Tahasang pahintulot mula sa mga makikilalang tagapagsalita
content_rights_confirmed	boolean	Parehong mga mode	Pagmamay-ari o wastong lisensya sa nilalaman
eula_accepted	boolean	Parehong mga mode	Tinatanggap ang Addavox EULA
attested_by	string	Parehong mga mode	Email o pagkakakilanlan ng responsableng partido
attested_at	ISO 8601	Parehong mga mode	Sa loob ng 24 oras mula sa oras ng kahilingan

HTTP	Kodigo	Kundisyon
403	CONSENT_MISSING	Walang bagay na pumayag
403	CONSENT_INCOMPLETE	Kulang ang attested_by o hindi wasto ang attested_at
403	CONSENT_NOT_AFFIRMED	Hindi pinagtibay ang mga Karapatan o EULA
403	CONSENT_EXPIRED	pinatunayan_nang mas matanda sa 24 na oras
403	SPEAKER_CONSENT_REQUIRED	voice_matched nang walang pahintulot ng nagsasalita
400	INVALID_MODE	Hindi wastong halaga ng mode

API Pagpepresyo ng Serbisyo

Ang mga indibidwal na serbisyo ay sinisingil kada minuto at hindi bahagi ng isang plano — magbabayad ka lamang para sa iyong tinatawagan, sa isang patag na rate na walang taunang diskwento. Tanging ang full video localization lamang ang gumagamit ng mga minutong kasama sa isang plano. Ang mga serbisyong nakabatay sa teksto ay sumusukat sa humigit-kumulang 1,000 karakter kada minuto.

Serbisyo	Ang ipinapadala mo → ang natatanggap mo	I-rate
Paghihiwalay ng Boses	Audio → malinis na boses + mga track sa background	$0.02/min
Transkripsyon (STT)	Audio → transkripsyon ng teksto na may bantas at tiyempo sa antas ng salita	$0.02/min
Propesyonal na Transkripsyon	Audio → Paghihiwalay ng Boses + Transkripsyon (STT), pinakamahusay para sa maingay na audio	$0.05/min
Pagsasalin	Teksto → isinalin na teksto	$0.02/min
Magsalaysay (TTS)	Teksto → isinalaysay na audio sa isang paunang natukoy na boses	$0.03/min
Isalin + Isalaysay — naka-set na boses	Teksto → isinalin, pagkatapos ay isinalaysay sa isang paunang natukoy na boses	$0.06/min
Isalin + Isalaysay — magkatugmang boses	Teksto + isang sample ng boses na ≥1 minuto → isinalin, pagkatapos ay isinalaysay sa katugmang boses. Dapat magkaiba ang pinagmulan at target na wika.	$0.08/min

Ang full video localization ay ang tanging serbisyong API na nakatali sa isang plano: kumukuha ito ng mga kasama na minuto ng iyong plano, pagkatapos ay may overage sa rate ng plano. Tingnan ang mga plano at presyo
