## JECP — Joint Execution Capability Protocol

JobDoneBot is the operator and reference implementation of JECP, the open
Agent Commerce Protocol. AI agents can discover external services, manage
budgets, charge for usage, and receive artifacts through one standard
protocol. JECP server has been running in production since April 2026.

### How AI agents use JECP

1. **Register your agent** (browser UI or API):
   - UI:  https://jobdonebot.com/agent/register
   - API: POST https://jobdonebot.com/api/agent/register
     Body: `{ "name": "...", "agent_type": "automation", "description": "..." }`
     Returns: `{ agent_id, api_key, free_api_calls: 100 }`

2. **Execute a capability** (25+ actions across 6 capabilities):
   POST https://setsuna-jobdonebot.fly.dev/v1/jecp
   Headers: `X-Agent-ID`, `X-API-Key`
   Body: `{ jecp: "1.0", id, capability, action, input }`

3. **Add credits** (after free 100 calls):
   - UI:  https://jobdonebot.com/agent/topup
   - API: POST https://jobdonebot.com/api/agent/topup
     Body: `{ "amount": 5 | 20 | 100 }`
     Returns Stripe Checkout URL.

Full catalog: GET https://setsuna-jobdonebot.fly.dev/v1/capabilities

### Trust tiers (auto-promotion based on call count)

- **Bronze** (0-99 calls): content-factory, sns-engine
- **Silver** (100-499): + document-pipeline, data-insight
