# Timmy API — Test Plan & Report Prompt

**What is Timmy?**
Timmy is a Lightning Network-gated AI agent API. Users pay Bitcoin (via Lightning) to submit requests to an AI agent (Claude). Two payment modes:

- **Mode 1 — Per-Job (live):** Pay per request. Eval invoice (10 sats fixed) → Haiku judges the request → work invoice (dynamic, token-based) → Sonnet executes → result delivered.
- **Mode 2 — Session (live):** Pre-fund a credit balance. Requests automatically debit actual compute cost (eval + work tokens × 1.4 margin, converted to sats at live BTC/USD). No per-job invoices once active.

**Live base URL:**
```
https://9f85e954-647c-46a5-90a7-396e495a805a-00-clz2vhmfuk7p.spock.replit.dev
```

---

## Running the full test suite — one command

```bash
curl -s https://9f85e954-647c-46a5-90a7-396e495a805a-00-clz2vhmfuk7p.spock.replit.dev/api/testkit | bash
```

The server returns a self-contained bash script with the base URL already baked in.
Requirements: `curl`, `bash`, `jq` — nothing else.

> **Note for repeat runs:** Tests 7 and 8c hit `GET /api/demo`, which is rate-limited to 5 req/hr per IP. If you run the testkit more than once in the same hour from the same IP, those two checks will return 429. This is expected behaviour — the rate limiter is working correctly. Run from a fresh IP (or wait an hour) for a clean 20/20.

## What the testkit covers

### Mode 1 — Per-Job (tests 1–10)

| # | Name | What it checks |
|---|------|----------------|
| 1 | Health check | `GET /api/healthz` → HTTP 200, `status=ok` |
| 2 | Create job | `POST /api/jobs` → HTTP 201, `jobId` + `evalInvoice.amountSats=10` |
| 3 | Poll before payment | `GET /api/jobs/:id` → `state=awaiting_eval_payment`, invoice echoed, `paymentHash` present in stub mode |
| 4 | Pay eval invoice | `POST /api/dev/stub/pay/:hash` → `{"ok":true}` |
| 5 | Eval state advance | Polls until `state=awaiting_work_payment` OR `state=rejected` (30s timeout) |
| 6 | Pay work + get result | Pays work invoice, polls until `state=complete`, `result` non-empty (30s timeout) |
| 7 | Demo endpoint | `GET /api/demo?request=...` → HTTP 200, coherent `result` |
| 8a | Missing body | `POST /api/jobs {}` → HTTP 400 |
| 8b | Unknown job ID | `GET /api/jobs/does-not-exist` → HTTP 404 |
| 8c | Demo missing param | `GET /api/demo` → HTTP 400 |
| 8d | 501-char request | `POST /api/jobs` with 501 chars → HTTP 400 mentioning "500 characters" |
| 9 | Rate limiter | 6× `GET /api/demo` → at least one HTTP 429 |
| 10 | Rejection path | Adversarial request goes through eval, polls until `state=rejected` with a non-empty `reason` |

### Mode 2 — Session (tests 11–16)

| # | Name | What it checks |
|---|------|----------------|
| 11 | Create session | `POST /api/sessions {"amount_sats":200}` → HTTP 201, `sessionId`, `state=awaiting_payment`, `invoice.amountSats=200` |
| 12 | Poll before payment | `GET /api/sessions/:id` → `state=awaiting_payment` before invoice is paid |
| 13 | Pay deposit + activate | Pays deposit via stub, polls GET → `state=active`, `balanceSats=200`, `macaroon` present |
| 14 | Submit request (accepted) | `POST /api/sessions/:id/request` with valid macaroon → `state=complete` OR `state=rejected`, `debitedSats>0`, `balanceRemaining` decremented |
| 15 | Request without macaroon | Same endpoint, no `Authorization` header → HTTP 401 |
| 16 | Topup invoice creation | `POST /api/sessions/:id/topup {"amount_sats":500}` with macaroon → HTTP 200, `topup.paymentRequest` present, `topup.amountSats=500` |

### Nostr identity + trust engine (tests 25–36)

| # | Name | What it checks |
|---|------|----------------|
| 25 | Challenge nonce | `POST /api/identity/challenge` → HTTP 200, `nonce` is 64-char hex, `expiresAt` is ISO in future |
| 26 | Verify: missing event | `POST /api/identity/verify {}` → HTTP 400, non-empty `error` |
| 27 | Verify: unknown nonce | `POST /api/identity/verify` with fake nonce in content → HTTP 401, `error` contains "Nonce not found" |
| 28 | Me: no token | `GET /api/identity/me` without header → HTTP 401, `error` contains "Missing" |
| 29 | Me: invalid token | `GET /api/identity/me` with `X-Nostr-Token: totally.invalid.token` → HTTP 401 |
| 30 | Sessions: bogus token | `POST /api/sessions` with `X-Nostr-Token: badtoken` → HTTP 401, no `sessionId` in response |
| 31 | Jobs: bogus token | `POST /api/jobs` with `X-Nostr-Token: badtoken` → HTTP 401 |
| 32 | Sessions anonymous tier | `POST /api/sessions` (no token) → HTTP 201, `trust_tier == "anonymous"` |
| 33 | Jobs anonymous tier | `POST /api/jobs` (no token) → HTTP 201, `trust_tier == "anonymous"` |
| 34 | GET jobs/:id includes tier | `GET /api/jobs/:id` → HTTP 200, `trust_tier` non-null (anonymous job → `"anonymous"`) |
| 35 | GET sessions/:id includes tier | `GET /api/sessions/:id` → HTTP 200, `trust_tier == "anonymous"` |
| 36 | Full challenge→sign→verify | Inline node script: generate keypair, challenge, sign kind=27235 event, verify → token; GET /identity/me → tier=new, pubkey matches |

## Architecture notes for reviewers

### Mode 1 mechanics
- Stub mode is active (no real Lightning node). `paymentHash` is exposed on GET responses so the testkit can drive the full payment flow automatically. In production (real LNbits), `paymentHash` is hidden.
- `POST /api/dev/stub/pay/:hash` is only mounted when `NODE_ENV !== 'production'`.
- State machine advances server-side on every GET poll — no webhooks.
- AI models: Haiku for eval (cheap gating), Sonnet for work (full output).
- **Pricing:** eval = 10 sats fixed. Work invoice = actual token usage (input + output) × Anthropic per-token rate × 1.4 margin, converted at live BTC/USD. This is dynamic — a 53-char request typically produces an invoice of ~180 sats, not a fixed tier. The old 50/100/250 sat fixed tiers were replaced by this model.
- Max request length: 500 chars. Rate limiter: 5 req/hr/IP on `/api/demo` (in-memory, resets on server restart).

### Mode 2 mechanics
- Minimum deposit: 100 sats. Maximum: 10,000 sats. Minimum working balance: 50 sats.
- Session expiry: 24 hours of inactivity. Balance is forfeited on expiry. Expiry is stated in the `expiresAt` field of every session response.
- Auth: `Authorization: Bearer <macaroon>` header. Macaroon is issued on first activation (GET /sessions/:id after deposit is paid).
- Cost per request: (eval tokens + work tokens) × model rate × 1.4 margin → converted to sats. If a request starts with enough balance but actual cost pushes balance negative, the request still completes and delivers — only the *next* request is blocked.
- If balance drops below 50 sats, session transitions to `paused`. Top up via `POST /sessions/:id/topup`. Session resumes automatically on the next GET poll once the topup invoice is paid.
- The same `POST /api/dev/stub/pay/:hash` endpoint works for all invoice types (eval, work, session deposit, topup).

### Eval + work latency (important for manual testers)
The eval call uses the real Anthropic API (Haiku), typically 2–5 seconds. The testkit uses polling loops (max 30s). Manual testers should poll with similar patience. The work call (Sonnet) typically runs 3–8 seconds.
