Add Ando MPP inference service

[JamieAlethieum]

Summary

Add Ando to the curated MPP services directory as a first-party Tempo MPP
session inference service.

The entry points agents at https://inference.andoai.xyz and documents the
live POST /v1/mpp/chat/completions endpoint with dynamic token-metered
pricing, a 1 USDC.e cumulative voucher bucket, and a 5 USDC.e suggested
reusable session deposit.

Required checklist

• Service is live and accepting MPP payment challenges
• Added service entry to schemas/services.ts
• Types pass: pnpm check:types
• Build succeeds: pnpm build

Validation

• pnpm generate:discovery
• pnpm check:types
• pnpm test schemas/services.test.ts
• pnpm build
• git diff --check

Local notes:

• Ando is not currently present in https://mpp.dev/api/services.
• Unpaid probe to POST https://inference.andoai.xyz/v1/mpp/chat/completions
  returned 402 with WWW-Authenticate: Payment, realm="inference.andoai.xyz",
  method="tempo", and intent="session".
• Public docs links return 200:
  • https://docs.andoai.xyz/docs/agents/tempo-mpp-inference
  • https://docs.andoai.xyz/docs/developers/api-reference/mpp-chat-completions

Environment note:

This local environment did not have global pnpm or Node 24 on PATH. Validation
used the repo-pinned pnpm@10.22.0 and ephemeral Node 24 via npx, with
caches redirected to /tmp.

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.

Preserve Ando's token unit in discovery output

For this dynamic endpoint, unitType: "token" is dropped by buildPayment in scripts/generate-discovery.ts because that function only copies unitType in the fixed-price branch. In contexts that consume generated /api/services data or the MCP services worker's exact unitType filter/facet, Ando won't be discoverable as a token-metered service even though the registry entry declares it that way; either serialize unitType for dynamic payments or don't rely on this field here.
