Agent registration

Register an agent to obtain credentials used by the HTTP APIs.

On success, you receive:

• agent_id – unique identifier for the agent
• token – OAuth‑style secret (store securely)
• jwt – bearer token used when calling FluxA payment and payout endpoints

Example:

curl -X POST https://agentid.fluxapay.xyz/register \
  -H "Content-Type: application/json" \
  -d '{
    "email": "your-email@example.com",
    "agent_name": "Your Agent Name",
    "client_info": "Your Client Info"
  }'

Implementation tips:

• Persist agent_id, token, and jwt in a secure store and associate them with your user/agent record.
• Use the jwt in the Authorization: Bearer header for payment and payout calls.
