API Keys and Authentication#

One key does everything. A single sl_live_... Labs key authenticates Labs Cloud, the whole Supafone product API, the MCP server, and both SDKs — as long as an app.supafone.ai account exists with the same email that owns the key. Set export SUPAFONE_TOKEN=sl_live_... and you are done; there is no second key to provision. Legacy scoped sf_live_... keys still work for hosted-agent-only use, but they are the exception, not the default.

One key covers both surfaces:

Key	Base URL	Used for
`sl_live_...`	`https://api.labs.supafone.ai` and `https://api.supafone.ai`	Everything: Labs Cloud oracle, TTS, STT, logs, usage, builder, QA, optimizer — plus the whole product API (campaigns, calls, agents) via one-key auth
`sf_live_...` (legacy)	`https://api.supafone.ai/api/v1/labs`	Optional scoped key for hosted-agent-only use — the `sl_` key already covers this surface

One Key, Both APIs#

An sl_ key is no longer labs-only. The Supafone product API (https://api.supafone.ai) accepts it as a bearer credential anywhere an account JWT works: on first use it introspects the key against GET https://api.labs.supafone.ai/v1/keys/introspect, maps the key's owner email to your app.supafone.ai account, and caches the validated key in-process for ~5 minutes. Anything doubtful — unknown key, deactivated key, labs outage — fails closed as a 401, never a fallback.

bash

export SUPAFONE_TOKEN=sl_live_...   # ONE env var: MCP + both SDKs, end to end

curl https://api.supafone.ai/api/v1/campaigns \
  -H "Authorization: Bearer $SUPAFONE_TOKEN"

Requirements:

An app.supafone.ai account must exist with the same email that owns the

key — otherwise the API answers 401 with "create an app.supafone.ai account with the same email".

The key must be active in the labs console.

Account login (email/password or JWT) keeps working exactly as before — the sl_ path is additive.

Labs Cloud Auth#

Create a trial key:

bash

curl -X POST https://api.labs.supafone.ai/v1/signup \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com"}'

Use it as a bearer token:

bash

curl https://api.labs.supafone.ai/v1/usage \
  -H "Authorization: Bearer $SUPAFONE_LABS_API_KEY"

The TypeScript SDK uses this key as apiKey for Labs Cloud methods:

const supafone = new Supafone({
  apiKey: process.env.SUPAFONE_LABS_API_KEY!,
});

Legacy Scoped Hosted-Agent Keys#

Your one sl_ key already authenticates the hosted-agent API via one-key auth, so most integrations never need a second key:

bash

curl https://api.supafone.ai/api/v1/labs/capabilities \
  -H "Authorization: Bearer $SUPAFONE_LABS_API_KEY"

For hosted-agent-only deployments you can still mint a scoped sf_live_... key from the Supafone account-admin flow. It is the exception, not the default.

The hosted-agent API also accepts x-supafone-key and x-supafone-api-key, but bearer auth is the recommended default.

The recommended TypeScript setup for every public surface is one token:

const supafone = new Supafone({
  apiKey: process.env.SUPAFONE_TOKEN!,
});

Separate per-surface credentials remain an advanced compatibility option for teams that deliberately want scoped keys:

const supafone = new Supafone({
  apiKey: process.env.SUPAFONE_LABS_API_KEY!,
  supafoneApiKey: process.env.SUPAFONE_API_KEY!,
});

Creating Hosted-Agent Keys#

Hosted-agent key management is an account-admin operation on the Supafone app API. It uses the normal app user session or JWT, not the hosted-agent key being created.

http

POST   /api/v1/labs/api-keys
GET    /api/v1/labs/api-keys?agency_id=...
DELETE /api/v1/labs/api-keys/{key_id}?agency_id=...

Create body:

json

{
  "agency_id": "00000000-0000-0000-0000-000000000000",
  "name": "Production key",
  "scopes": [
    "agents:write",
    "agents:read",
    "voices:read",
    "calls:write",
    "numbers:read",
    "numbers:write",
    "telephony:read",
    "telephony:write"
  ]
}

The raw sf_live_... value is returned once. List and revoke responses should only expose prefixes or metadata.

Console Sessions#

Labs Cloud also supports account sessions for console-scoped features:

http

POST /v1/auth/register
POST /v1/auth/login
POST /v1/auth/key-login
GET  /v1/account
POST /v1/account/keys
PATCH /v1/account/keys/{key}

Builder and QA methods require a session token. Most read and usage endpoints accept either a session token or an sl_live_... key.

Key Hygiene#

Never commit sl_live_..., sf_live_..., provider keys, Twilio credentials,

Stripe secrets, or admin secrets.

Use environment variables in examples, tests, and deploys.
Show only masked keys in dashboards and logs.
Rotate keys when they leave the intended environment.
