# KEVAREMESH — AI Agent Commerce Infrastructure
Last editorial update: 2026-10-28 JST. The authoritative current merchant status is the native x402 resource listing, not this static document.

## Current offer and real commercial boundary
- Twenty-four original KEVAREMESH API/Tool product catalog entries exist. Twenty-one use bounded no-upstream pure algorithms; three network-dependent products remain withheld from paid execution.
- Original first-party product pricing: 0.001 USDC per invocation, except UUID generation 0.005 USDC. Prices are in Base USDC, network eip155:8453.
- The original Base64 Transform `base64-transform` has merchant catalog flags enabled for **one initial order only**. All other 23 entries are not enabled for paid execution. Exactly which x402 URL is currently payable must be established from the authoritative dynamic merchant manifest below; do not send USDC if it is not listed.
- Last private commercial ledger review: no verified external buyer payment, no completed onchain settlement and no paid result retrieval recorded. No sales are guaranteed.
- Buyer pays directly from its own authorized x402 client. Discovery/metadata GET is free and cannot sign, transfer, or execute external supplier APIs.

## Owned paid API buyer route (conditional on the live listing)
- Current paid merchant resource manifest: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-owned-x402-v1/.well-known/x402
- Existing Base64 Transform purchase URL, only when genuinely enabled by the manifest: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-owned-x402-v1/execute/base64-transform
- Verified first-party product schema: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-owned-pure-preview-v1/contract/base64-transform
- Current merchant product metadata: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-owned-docs-v1?slug=base64-transform&kind=meta
- Before any payment, compare the real HTTP 402 challenge amount, network, USDC asset and payTo with the authoritative merchant listing and enforce the buyer's pre-authorized agent spending policy or request per-purchase approval. The merchant does not provide or override buyer wallet permissions.
- Keep the privately generated receipt ID. Reconcile via `/receipt/reconcile`, then retrieve the original result via `/receipt/result` after independent onchain USDC confirmation. A held or uncertain receipt must never be paid twice.
- If a paid HTTP response was lost before the buyer received the receipt UUID, the buyer can compute SHA-256 of the exact original Payment-Signature header LOCALLY and supply **only** the 64-hex fingerprint to the free `/receipt/locate` endpoint. Never send the original signed payment header to this endpoint. The fingerprint is a bearer secret; do not put it in URLs, logs or email. MCP tool: `kevaremesh_locate_owned_receipt`. This locates an existing reservation and never signs, sends funds or re-executes the paid API.

## Agent-native API procurement and discovery
- Read-only AI-first entry index (one URL to find MCP, catalog, OpenAPI, live x402 merchant and Gateway): https://kevaremesh-wallet-proof.floot.app/agent-entry.json
- This self-hosted JSON is an integration index, not evidence of MCP Registry or x402 Bazaar acceptance. External client connection and catalog inclusion must be independently confirmed.
- Main website: https://kevaremesh-wallet-proof.floot.app/
- Agent discovery MCP, 12 tools: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-agent-discovery-mcp-v1
- Current MCP descriptor: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-agent-discovery-mcp-v1/server.json
- Original 24-product catalog: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-owned-catalog-v1
- Third-party provider metadata: https://fpgtwgtoqtokpitzlbie.supabase.co/functions/v1/kevaremesh-gateway-failover/catalog
- Agent task routing: `kevaremesh_route_intent` tool within the MCP; returns owned candidates, price, actual native x402 purchase eligibility and bounded first-party input schemas.
- Free multi-provider quotation: `kevaremesh_quote_provider_batch` within MCP, for 1–5 capabilities. Quote metadata does not grant supplier API rights.
- Gateway route fee model remains 0.001 USDC per authorized route preparation, but new paid third-party route preparation is not confirmed enabled. Provider fees are buyer-direct and are not KEVAREMESH revenue.

## Accuracy and safeguards
- Do not confuse a public catalog entry, input-contract preview, a 402 challenge, facilitator message or simulated demonstration with a completed third-party sale.
- Do not attempt a purchase without a live certified and individually enabled native x402 resource, real buyer authority, applicable rights, exact current price/recipient confirmation and independently verified USDC settlement.
- Never submit private wallet keys, seed phrases, raw payment signatures, bearer receipt IDs or confidential buyer data to public sites or support email.
- The 21-item pure preview set is distinct from current paid availability, and this document does not constitute proof of actual paid delivery.
