Summary

Adds Stelar Crypto Signals (api.stelardigital.com) to the MPP service registry.

  • Live x402-payable API on Base (USDC), 15 paid endpoints: crypto market signals (price/momentum, market regime, volatility, sentiment, token risk), combined market-brief bundles, live grid-bot P&L telemetry, and a few general-purpose AI text utilities (classify/summarize/extract/markdown/factcheck).
  • Discovery manifest: https://api.stelardigital.com/.well-known/x402
  • Machine-readable catalog: https://api.stelardigital.com/catalog
  • OpenAPI spec: https://api.stelardigital.com/openapi.json
  • Verified live before submitting: curl -i https://api.stelardigital.com/telemetry returns HTTP/2 402 with a valid payment-required header (x402 v2, scheme exact, network eip155:8453, USDC asset, payTo set).

Endpoint routes, prices, and descriptions in this PR were pulled directly from the live catalog above — nothing invented.

Test plan

  • pnpm check:types — passes
  • pnpm check — passes (no formatting changes needed)
  • pnpm build — passes (SSG completes; pre-existing repo requirement for a local MPP_SECRET_KEY env var to build the demo page is unrelated to this change — reproduced identically on unmodified main)

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.
