Add PreFlyte to service directory

[hayespeter]

Summary

Adds PreFlyte — a DeFi financial intelligence service for AI agents — to the MPP service directory.

PreFlyte is live on Tempo mainnet USDC and already registered on MPPScan. It exposes 9 paid REST endpoints at https://pay.preflyte.xyz via mppx/express, with per-endpoint pricing from $0.01–$0.05.

What PreFlyte does

Answers "is it smart?" for DeFi agents — orthogonal to security products like Blockaid/GoPlus which answer "is it safe?". The headline tool, assess_opportunity, gives agents cold-start orientation (where to deploy capital for a given position size and strategy) in a single call.

Coverage: Aave V3, Compound V3, Uniswap V3, and Lido across Ethereum and Arbitrum. Data collected directly from on-chain sources.

Endpoints added

Endpoint	Price	Purpose
GET /assess_opportunity	$0.05	Cold-start orientation — ranked opportunities for a given position size and strategy

All priced in USDC (6 decimals). Payment method: TEMPO_PAYMENT.

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.

Checklist verification, running locally on Node 24:

• pnpm check:types — passes (no output = clean tsc --noEmit)
• pnpm build — passes, all 5 build stages complete, SSG generates

The Vercel red check above is a fork-permission artifact (Vercel can't deploy from an external fork without team authorization), not a build failure. The repo-side workflows all passed.

PreFlyte is live on Tempo mainnet USDC (chain 4217) and registered on MPPScan. Happy to address any review feedback.
