Chat Series Overview - Vidgo API

All Chat Series endpoints use https://api.vidgo.ai and a Vidgo API key. Send the key as Authorization: Bearer YOUR_API_KEY. Claude clients may also use x-api-key; Gemini clients may use x-goog-api-key.

Model protocol support

The Gemini-compatible endpoints are available for future Gemini-capable models. None of the six models above currently supports that protocol.

Pricing

Prices are Vidgo credits per one million tokens. The final charge is calculated from the usage returned by the model, with a minimum positive charge of 0.001 credit.

Model	Input	Output	Cache read	Cache write
`gpt-5-6-luna`	11.2	67.2	1.12	14
`gpt-5-6-terra`	112	672	11.2	140
`gpt-5-6-sol`	280	1680	28	350
`kimi-k3`	456	2280	456	456
`claude-sonnet-5`	170	855	170	170
`claude-opus-5`	400	2000	40	500 (5m), 800 (1h)

Both normal JSON responses and SSE streaming are supported. Vidgo settles credits after the final usage event. If a provider omits usage but produced output, Vidgo estimates token usage and marks the audit record as estimated. Requests with no valid output are not charged.
