# STELLARSIGHT

> The facilitator-side Bazaar discovery layer for x402 on Stellar.

## Docs

- [Find what to pay for on Stellar](https://docs.stellarsight.xyz/index.md): STELLARSIGHT is the facilitator-side Bazaar discovery layer for x402 — the catalog, the search and the agent surface, with the whole payment loop running around it on Stellar testnet.
- [Verify in 60 seconds](https://docs.stellarsight.xyz/quickstart.md): Nothing here asks for trust. Every claim is checkable against a live endpoint, a public explorer or a command you run yourself.
- [Seller quickstart](https://docs.stellarsight.xyz/guides/seller.md): Clone to a paid, discoverable endpoint in 59 measured seconds. No faucet, no captcha, no API key.
- [Agent & MCP](https://docs.stellarsight.xyz/guides/agent.md): Discover and pay for services from an agent: the MCP server's four tools and the CLI.
- [Architecture](https://docs.stellarsight.xyz/architecture.md): The full system design: components, data flow, trust boundaries and the seven diagrams.
- [API contract](https://docs.stellarsight.xyz/api/contract.md): Every HTTP surface, wire shape and field name — the contract the conformance harness enforces.
- [Threat model](https://docs.stellarsight.xyz/security/threat-model.md): Twelve threats, each mapped to the control that answers it and the test that proves it.
- [Monitoring plan](https://docs.stellarsight.xyz/security/monitoring.md): Signal, threshold and response per surface — what exists today and what is funded work.
- [Settled transactions](https://docs.stellarsight.xyz/evidence/testnet-transactions.md): Every settled testnet payment, with explorer links.
- [Search evaluation](https://docs.stellarsight.xyz/evidence/search-eval.md): nDCG@10 0.864 over a 50-query graded set, with method, caveats and a CI regression gate.
- [Load baseline](https://docs.stellarsight.xyz/evidence/load-baseline.md): 4/4 serial vs 1/10 concurrent on a single fee-payer — the before Tranche 1 has to beat.
- [Position on upto](https://docs.stellarsight.xyz/upto-position.md): The discovery-side requirements for the Stellar upto scheme, as argued upstream.
