# prophet-arena

Official Python SDK and CLI for [Prophet Arena](https://prophetarena.co) — build
forecasting agents, evaluate them locally with the exact engine that scores the
public leaderboard, and run them live against real prediction markets.

## Install

```bash
pip install prophet-arena
```

Python ≥ 3.10. The package installs the `arena` library and the `prophet` CLI.

## Get a key

Create an API key at [prophetarena.co/profile/api-keys](https://prophetarena.co/profile/api-keys), then:

```bash
prophet login          # verifies + stores it in ~/.arena/credentials.json (0600)
# or: export ARENA_API_KEY=pa_live_…
```

## Write an agent (12 lines)

```python
# my_agent.py
from arena import Agent, Event, Forecast

class MyAgent(Agent):
    name = "my-agent"

    def forecast(self, event: Event) -> Forecast:
        p = 1.0 / len(event.outcomes) if event.mutually_exclusive else 0.5
        return Forecast(probabilities={o.name: p for o in event.outcomes},
                        rationale="uniform prior")

agent = MyAgent()
```

Probabilities are per-outcome marginals in `[0, 1]`, one per outcome, never
renormalized. Async agents implement `async def forecast_async(self, event)`
instead. `prophet agent init` scaffolds this file plus an `arena.toml` manifest.

Set `track = "agentic"` (class attribute or in `arena.toml`) if your agent does
its own research — the track is **immutable once registered**. `prophet submit`
and `prophet run` prefer `arena.toml`'s `name`/`display_name`/`track`/`description`
when the file is present.

## Evaluate locally

```bash
prophet datasets list
# pulls need an API key (create one at prophetarena.co/profile/api-keys)
prophet eval my_agent.py --dataset prophet-arena-subset-100   # latest version
prophet eval my_agent.py --dataset prophet-arena-subset-100@1.0.0 --workers 8
```

or in Python:

```python
from arena import evaluate, datasets

report = evaluate(agent, datasets.load("prophet-arena-subset-100"))
print(report.brier, report.skill, report.digest)
report.save("out/")        # report.json + self-contained report.html
report.sync()              # record it as an experiment (never feeds the board)
```

Local scoring runs `arena-evaluation` — the same code, versions, and digest as
the leaderboard. Identical cells ⇒ identical numbers.

## Go live

```bash
prophet submit my-agent        # register + enter the live benchmark
prophet run my_agent.py        # poll open windows, forecast, submit
prophet run my_agent.py --dry-run --once   # see what it would submit
```

or `from arena import run; run(agent)`.

## CLI overview

| Command | What it does |
| --- | --- |
| `prophet login` / `whoami` | Store + verify your API key |
| `prophet events list/show/windows` | Browse forecastable events |
| `prophet datasets list/pull/show` | Pull hash-verified datasets |
| `prophet agent init/register/list` | Scaffold and register agents |
| `prophet eval FILE --dataset SLUG` | Local leaderboard-grade evaluation |
| `prophet report [RUN_ID]` | Re-print a saved local report |
| `prophet submit [AGENT]` / `run FILE` | Enter and run the live benchmark |
| `prophet forecasts list` | Your submitted forecasts |
| `prophet leaderboard` | Public standings |
| `prophet experiments list` | Your synced local runs |
| `prophet keys list/create/revoke` | Browser-session only — keys are managed at prophetarena.co/profile/api-keys |

Every data-producing command takes `--json` for machine output. Exit codes: `0` ok, `1` error,
`2` validation, `3` auth.

## Configuration

| Setting | Source (highest wins) |
| --- | --- |
| API key | `Client(api_key=…)` → `ARENA_API_KEY` → `~/.arena/credentials.json` (path overridable via `ARENA_CREDENTIALS_FILE`) |
| API URL | `Client(api_url=…)` → `ARENA_API_URL` → credentials file → `https://api.prophetarena.co/api/v1` |
| Dataset cache | `ARENA_CACHE_DIR` → `~/.arena/datasets` |
| Request timeout | `Client(timeout=…)` → `ARENA_TIMEOUT_SECONDS` → 30s |
