# Lightning Rod Labs - Predict anything with AI

We train LLMs on messy, real-world data. Our small models out-predict frontier models at a fraction of the cost. Try our public Foresight Models today, or train an unmatched AI expert for your domain - using the messy data you already have.

Our latest forecasting model Foresight v4 outperforms all benchmarked SOTA models on price & accuracy on a benchmark of general prediction questions from Polymarket.

## Agentic access (pay with MPP)

Agents obtain an API key and credits without a human — no signup, no dashboard.

Fastest path, if you have a Tempo wallet (`tempo wallet login`):

```
tempo request -X POST https://api.lightningrod.ai/v1/mpp/topup
```

This pays the $5.00 USDC-on-Tempo challenge and returns credits + an API key automatically. Any other MPP-aware client (`mppx`, `link-cli`) works the same way — point it at the URL below.

### Manual flow (raw HTTP, any MPP client)

1. Request a challenge (no payment):

```
curl -s -X POST https://api.lightningrod.ai/v1/mpp/topup
```

Returns `402` with **two** `WWW-Authenticate: Payment` header instances — pay whichever rail you can:

```
WWW-Authenticate: Payment id="...", realm="api.lightningrod.ai", method="stripe", intent="charge", request="<base64url>", expires="2026-01-01T00:00:00Z", description="Lightning Rod Labs credit top-up ($5.00)"
WWW-Authenticate: Payment id="...", realm="api.lightningrod.ai", method="tempo", intent="charge", request="<base64url>", expires="2026-01-01T00:00:00Z", description="Lightning Rod Labs credit top-up ($5.00)"
```

`method="tempo"` — on-chain USDC on Tempo (chain id 4217). `method="stripe"` — Stripe card/Link Shared Payment Token. `request` is base64url-encoded JSON per the MPP spec (`draft-ietf-httpauth-payment`); decode it for the exact recipient/amount, or read the machine-readable offers (amount, currency, decimals) in `x-payment-info` at https://api.lightningrod.ai/openapi.json.

2. Pay with your wallet/CLI (it builds and signs the credential for you) and retry with `Authorization: Payment <credential>`:

```
curl -s -X POST https://api.lightningrod.ai/v1/mpp/topup \
  -H 'Authorization: Payment <credential-from-step-2>'
```

Returns `200`:

```json
{"organization_id": "org_mpp_...", "credited_cents": 500, "api_key": "sk_...", "api_key_id": "key_..."}
```

`api_key` is minted once — save it.

3. Use it as `Authorization: Bearer sk_...` on `POST /openai/chat/completions`. When credits run out, that endpoint returns `402`; call `/mpp/topup` again with the same key in `X-API-Key` to refill without minting a new org.
