Seren API

Use this skill whenever a user needs direct platform-level Seren API calls (not just one publisher).

1. Registration

Register an agent and receive an API key (shown once).

POST /auth/agent

curl -sS -X POST "https://api.serendb.com/auth/agent" \
  -H "Content-Type: application/json" \
  -d '{}'

Optional named registration:

curl -sS -X POST "https://api.serendb.com/auth/agent" \
  -H "Content-Type: application/json" \
  -d '{"name":"my-agent"}'

The current response shape provides the key at .data.agent.api_key.

GET /auth/me

Check the current authenticated agent's identity:

curl -sS "https://api.serendb.com/auth/me" \
  -H "Authorization: Bearer $SEREN_API_KEY"

PATCH /auth/agent

curl -sS -X PATCH "https://api.serendb.com/auth/agent" \
  -H "Authorization: Bearer $SEREN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com"}'

A verified email is required before Stripe deposits. Updating the email sends a verification link — the user clicks the link to verify, no separate API call is needed.

2. Authentication

All authenticated requests require your API key in the Authorization header.

export SEREN_API_KEY="seren_<your_key>"

Authenticated request pattern

curl -sS "https://api.serendb.com/wallet/balance" \
  -H "Authorization: Bearer $SEREN_API_KEY"

Your API key is shown once at registration. If you lose it, use your recovery code (see Account Recovery).

Credential storage

The seren CLI stores credentials at:

• macOS/Linux: ~/.config/seren/credentials.toml
• Windows: %APPDATA%\\seren\\credentials.toml

You can also store your key in environment variables or your agent's memory/secrets store.

Helper scripts

The seren/api skill package includes wrapper scripts that auto-resolve credentials and simplify API calls:

# Bash/zsh — loads SEREN_API_KEY from env, credentials.toml, or mints a new key
eval "$(scripts/resolve_credentials.sh)"
scripts/seren_api.sh get /wallet/balance
scripts/seren_api.sh post /wallet/recovery --data '{}'

# PowerShell equivalent
.\scripts\resolve_credentials.ps1
.\scripts\seren_api.ps1 get /wallet/balance

Supported overrides:

• SEREN_API_HOST (default https://api.serendb.com)
• SEREN_CREDENTIALS_FILE (explicit file path)
• SEREN_AUTO_CREATE_KEY=0 (disable auto-mint)

3. Account Recovery

Essential recovery flow:

1. Set up recovery using authenticated endpoint:

POST /wallet/recovery

curl -sS -X POST "https://api.serendb.com/wallet/recovery" \
  -H "Authorization: Bearer $SEREN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"email":"you@example.com"}'

Save the recovery_code from the response — it is shown once and cannot be retrieved later.

2. Recover after key loss using recovery code:

POST /wallet/recover

curl -sS -X POST "https://api.serendb.com/wallet/recover" \
  -H "Content-Type: application/json" \
  -d '{"recovery_code":"ABCDEFGHJKLMNPQRSTUVWX23"}'

/wallet/recover rotates credentials and recovery code; save returned secrets immediately.

4. Wallet and Funding
