Accord/402 HTTP middleware. Express/Connect-compatible. Turn any HTTP endpoint into a paid, verifiable Accord engagement: 402 challenge with agreement template, replay-protected payment verification, structured error envelope. Rail-agnostic. See specs/ACC
A unified interface for compiled languages and templates in JavaScript
Get the default network gateway, cross-platform.
Shared Accord rail-adapter interface + a Mock adapter for tests/demos. Rail-specific implementations (Ergo, Rosen, Base, x402) re-export the interface from here. See specs/ACCORD-006-rails.md.
The Gateway provider for the [AI SDK](https://ai-sdk.dev/docs) allows the use of a wide variety of AI models and providers.
Parser for Concerto CTO files
Interface used to connect Apollo Gateway to Apollo Server
Accord rail adapter for the Ergo Note primitive. verifyPayment fetches the Note from the chain, checks expiry / reserve binding / task-hash / value; settle calls redeemNote and emits a v0 Settlement Receipt with mode=note_redeemed.
Utilities for Concerto Modeling Language
Accord Protocol core SDK — canonicalize, hash, validate Agreement / Verification Receipt / Settlement Receipt v0 objects. Rail-agnostic. See specs/ACCORD-000-overview.md.
Accord rail adapter for the Base / EVM Note primitive (AgentPayReserveV0). verifyPayment fetches the Note from the Solidity contract, checks expiry / receiver binding / task-hash / value; settle calls redeemNote and emits a v0 Settlement Receipt with mode
This document describes how `@paperclipai/adapter-openclaw-gateway` invokes OpenClaw over the Gateway protocol.
Core Implementation for the Concerto Modeling Language
Concerto metamodel utilities
Accord rail adapter for x402-compatible HTTP payments. Wraps any x402 facilitator (Coinbase, custom) into the AccordRailAdapter shape so x402 endpoints can settle Accord agreements atomically (pay_before_response).
AWS SDK for JavaScript Api Gateway Client for Node.js, Browser and React Native
Accord/MCP transport wrapper. Turn any MCP tool into a paid, verifiable Accord engagement: validate Agreement, verify payment via rail adapter, emit Verification + Settlement Receipts. Rail-agnostic. See specs/ACCORD-005-accord-mcp.md.
Command-line utility for working with Concerto model files
This document describes how `@penclipai/adapter-openclaw-gateway` invokes OpenClaw over the Gateway protocol.
Base / Ethereum-L2 implementation of the AgentPay v0 protocol. Reserve / Note / Acceptance Predicate semantics on EVM, denominated in any ERC-20 (USDC, USDT, …). Mirrors ergo-agent-pay's API shape so apps can pick the chain by config, not by rewriting.
Accord Protocol buyer-side policy enforcer. Wraps a buyer agent's signer with hard-coded spend limits, recipient and rail allow-lists, approval-required thresholds and atomic per-session budget tracking. Zero runtime deps. Designed for agentic wallets tha
