Add a9n9 Deep Research to the services directory

[starbackr-dev]

Adds a9n9 Deep Research (https://agent.a9n9.net) — an objective-driven deep-research service for agents, paid per request over MPP on Tempo mainnet.

What it does: an agent sends an objective (plus optional targetUrl focus hint) and gets a fixed quote bound to the request hash with a planned list of public source URLs; after payment a real cloud Chromium session visits each planned page and AI synthesis returns a cited cross-source report. Free daily quick search (news/arXiv) is included. Native MCP tools at https://agent.a9n9.net/mcp alongside REST.

Verification:

• npx mppx validate https://agent.a9n9.net — passes (15/15)
• Discovery: https://agent.a9n9.net/openapi.json · https://agent.a9n9.net/llms.txt · /.well-known/a9n9-agent.json
• Listed on MPPScan with live mainnet transaction history
• Runtime 402 challenges: method=tempo, intent=charge, USDC.e, realm agent.a9n9.net
• Payment recipient: 0x2D6424143693eB6ADc36C318468811D01B25DEFf

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 confirmation:

• Live and accepting MPP payments — yes, on Tempo mainnet since 2026-08-16. Verifiable: the service publishes its own paid evaluation with on-chain payment hashes for every run at https://agent.a9n9.net/eval (USDC.e transfers to 0x2D6424143693eB6ADc36C318468811D01B25DEFf, independently re-verified by an on-chain reconciliation job).
• Entry added to schemas/services.ts following the guide (changed-services bot picked it up above).
• Registered on MPPScan — live with transaction history: https://mppscan.com/ (origin agent.a9n9.net, 3 resources).
• npx mppx validate https://agent.a9n9.net passes 27/27.

Happy to adjust the entry if anything in the shape needs changing.

Gentle follow-up after 10 days — the checklist confirmation above still holds, and the service has stayed live and reliable in the interim (probe receipts and the public /eval page continue to accrue). Happy to make any changes needed to get this over the line. Thanks!
