Deepgram: 2 reads and 3 writes, one client

Speech-to-text that answers in the same request. Free credits on signup. Every call below is available over HTTP, through the SDK and as a tool for a coding agent, with the same arguments and the same meter.

What Deepgram can do here

The integration exposes 2 reads and 3 writes, each with a declared input and output schema rather than a page of documentation you would have to translate. Speech-to-text that answers in the same request. Free credits on signup.

How it authenticates

Deepgram authenticates with a apiKey, supplied per request or stored once against your account and sealed at rest. On our side the same value is read from apiKey when we broker the call for you.

Capabilities it fulfils

Deepgram answers ai.audio.transcribe in the vendor-neutral form, which means code asking for that capability can be pointed at Deepgram without naming it. If it goes down, or you would rather use somebody else, that is a preference change and not a rewrite.

• listProjects — read: Projects this key can reach. The cheapest call, so it is the connection test.
• transcribeUrl — write: Transcribe audio at a public URL. SYNCHRONOUS — the transcript comes back in this response.
• speak — write: Text to speech. Returns AUDIO BYTES.
• transcribeCallback — write: Transcribe asynchronously and POST the result to your own URL — for audio too long to wait on.
• usage — read: Requests and audio minutes consumed in a period.

Questions

Do I have to bring my own API keys?

You can, and that lane is free for ever — pass your key on the request or store it against your account, and we are one proxy hop. The paid lane is the other direction: we call 226 providers with our credentials so you never register anywhere. Both go through the same client and the same operation names.

What happens to a key I store here?

It is sealed with AES-256-GCM before it reaches the database and is only ever opened to make the call you asked for. It is scoped to your account, it is never logged, and deleting the connection deletes it. For an OAuth provider we hold a refresh token instead, and revoking the link at the provider stops the calls here immediately.

What happens when a provider changes its API?

The operation contract is declared, so a response that no longer matches is a refusal rather than a silently wrong answer. The contract does not coerce types — a field declared a number that arrives as a string is rejected at the edge, on the way in and on the way out.
