Add Lightning Rod Labs MPP services

[bartolomej]

Summary

Adds LightningRod (Lightning Rod Labs) to the service directory — an AI forecasting API that predicts anything via OpenAI-compatible endpoints, with structured answers (binary, multiple-choice, continuous, free-response), optional web research, and low/medium/high reasoning effort.

Unlike a per-request proxy, LightningRod uses a credit + API-key model: agents pay once over MPP at POST /v1/mpp/topup to fund a balance and receive an API key, then call the forecasting endpoints with that key. Accepts Stripe and Tempo USDC.e.

• Live service: https://api.lightningrod.ai
• OpenAPI: https://api.lightningrod.ai/openapi.json
• llms.txt: https://www.lightningrod.ai/llms.txt
• Homepage: https://lightningrod.ai

Endpoints

Only POST /v1/mpp/topup carries an MPP payment (charge, dynamic, $1–$10,000, default $5). The forecasting endpoints (/v1/openai/chat/completions, /v1/openai/completions, /v1/openai/models) authenticate with the API key returned by top-up and draw down the prepaid balance — no per-request MPP payment — so they are listed without an amount (rendered as "—", no intent badge) purely to surface the product's API surface. Each description states the balance requirement. A code comment in the entry documents this so the routes aren't mistaken for missing prices.

Required checklist

• Service is live and accepting payments via MPP (not a placeholder)
• Entry added to schemas/services.ts
• Types pass: pnpm check:types
• Biome clean: pnpm check
• Discovery regenerates: node scripts/generate-discovery.ts (LightningRod present in discovery.json + llms.txt)
• Build succeeds: pnpm build (verified locally; static generation emits LightningRod into the services bundle. Requires an MPP_SECRET_KEY ≥ 32 bytes — CI supplies the real secret)

Recommended

• Register on MPPScan — to be completed by Lightning Rod Labs

Thanks for submitting a service to the MPP directory!

If you want your service included in the curated mpp.dev/services list, complete this checklist before review:

Required

• Your service is live and accepting payments via MPP (not a placeholder or coming-soon)
• You've added your entry to schemas/services.ts following the contributing guide
• Types pass: pnpm check:types
• Build succeeds: pnpm build

Recommended

• Register your service on MPPScan (by Merit Systems) — it follows the standard MPP discovery format and makes your service discoverable by agents immediately, no PR required

Review criteria

We prioritize services that are high quality and novel. We may not approve services that duplicate existing functionality or aren't yet production-ready.
