It provides middleware for FastAPI, Starlette, and ASGI frameworks, plus client libraries for making authenticated payments automatically. The package integrates with CrewAI, MCP (Model Context Protocol), and A2A (agent-to-agent) protocols, enabling AI agents to monetize their services and pay for other agents' services within a single framework.\n\nThe core workflow is: define a price in USD using the price builder, register endpoints or tools with that price, then clients authenticate requests with EIP-712 signatures and blockchain payments. Settlement happens on-chain via smart contracts. The package includes templates for building payment-enabled MCP servers and utility agents, and it abstracts away most of the blockchain complexity\u2014you specify prices in USD and let the framework handle conversion and payment routing.","worth_installing":"Yes, with conditions. Install if you need to monetize AI agent services or APIs using blockchain payments and are comfortable with the Web3 stack. The low install friction and active maintenance are positive signals. However, verify the license terms before production use, confirm that Python 3.12+ is available in your environment, and understand that the 25 runtime dependencies mean you're adopting a fairly opinionated ecosystem\u2014use it when the D402 protocol and agent-payment model align with your architecture, not as a general payment library."},"id":"traia-iatp","links":{"html":"https://skillfed.io/packages/traia-iatp","md":"https://skillfed.io/packages/traia-iatp.md","pypi":"https://pypi.org/project/traia-iatp/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-05","license_spdx":null,"license_treatment":"unclear","name":"traia-iatp","python_support":"supports_current","summary":"Inter-Agent Transfer Protocol (IATP) - Enable AI Agents to utilize other AI Agents as tools"},"popularity":{"monthly_downloads":230050,"position":9117,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.1.112"}
