  • Grabbit

    grabbit.live

    An agent-first screenshot API that captures a hosted, pixel-perfect image of any URL through a one-line CLI, a hosted MCP server, or a plain REST call.

  • App2Api

    app2api.com

    A tool that reverse-engineers the real API behind a mobile app you own or are authorized to test, then hands an AI agent a runnable call and an OpenAPI spec for it.

  • Apitomy Codegen

    github.com

    Generates JAX-RS server stubs, Quarkus-optimized applications, data models and client libraries from OpenAPI specifications.

  • A replicable Google Cloud reference implementation of an enterprise-governed multi-agent system: a supervisor agent delegates to three specialist agents over the A2A protocol, with every model, MCP tool and agent call routed through Apigee for auth, quotas and token analytics.

  • Mockwave

    github.com

    An open-source, multi-protocol mock server for HTTP, GraphQL, SOAP, and gRPC, with weighted traffic splitting, dynamic JavaScript responses, chaos-testing fault injection, and an MCP server so an AI assistant can generate mock rules directly.

  • An MCP server that lets AI agents search, compare, and track prices across more than 300 million products from US, Singapore, and Southeast Asian merchants such as Lazada, Shopee, and Amazon.

  • PhoenixSpec

    github.com

    Generates an OpenAPI 3.1 specification for a Phoenix application automatically, by reading its Ecto schemas, JSON views and router instead of a separate spec file.

  • agents.txt

    agents-txt.com

    An open specification for a machine-readable file, agents.txt, that lets a website declare which agent-interaction protocols it supports -- authorization, payments, MCP servers, skill packages, and A2A -- without embedding protocol implementation details.

  • mtgo

    mtgo-labs.github.io

    A fast, idiomatic Go client library for the Telegram MTProto API, covering bots and user accounts, with generated protocol types, a handler and middleware system, a plugin lifecycle, pluggable storage backends and MTProxy support.

  • The core Laravel package of DreamFactory, a self-hosted platform that generates governed REST API access to any data source for enterprise apps and local LLMs.

  • The GraphQL code generation package for the Apollo iOS library, producing typed Swift code from GraphQL operations, used either through the Apollo iOS CLI or scripted directly for custom build pipelines.

  • The code generator for Soto, an AWS SDK for Swift, turning AWS Smithy service models into Swift client code, usable as a Swift Package Manager build plugin so a project only compiles the AWS services it actually uses.

  • An on-premise, Docker-distributed face liveness detection (anti-spoofing) server SDK that a developer runs on their own infrastructure and calls over a local HTTP API to check whether a submitted face image is a real, live person.

  • Elemm

    github.com

    A dynamic, manifest-driven communication framework, the Landmark Manifest Protocol, that lets an autonomous LLM agent discover and call distributed APIs on the fly instead of relying on static, hand-written tool definitions.

  • CoWorker Protocol

    ziwayzhao.github.io

    A peer-to-peer protocol that lets someone serve a private AI skill as a callable remote function over an encrypted channel, so a caller receives only the result and never the underlying prompt, code, or methodology.

  • ReqLab

    github.com

    An offline, account-free desktop API client built with Kotlin and Compose Multiplatform, supporting HTTP requests, streaming, and Model Context Protocol server testing as an alternative to Postman or Insomnia.

  • 2009scape-wiki-api

  • translate

    github.com

    A deterministic, on-device command-line translator for macOS Tahoe that also runs as an HTTP server compatible with the DeepL, LibreTranslate and Google Translate v2 APIs, with no cloud calls or LLM.

  • Day AI SDK

    github.com

    A TypeScript SDK for the Day AI CRM platform that exposes its MCP tools as a plain API for searching contacts, creating opportunities and pulling meeting transcripts.

  • Makra

    makralabs.org

    A Python and JavaScript SDK for the Makra web-extraction API, which reads a URL remotely against a supplied schema and returns the requested data as structured JSON.

  • A command-line tool that statically analyzes Go source code and generates an OpenAPI 3.1 spec, auto-detecting the web framework in use and following the call graph from routes to handlers to infer request and response types.

  • TogoLM

    togolm.com

    An open infrastructure layer for Togolese public data: a scraped corpus of laws, government records and press, a retrieval-augmented generation engine, and a REST API with JS/TS and Python client SDKs.

  • OTAIP

    telivity.app

    An open-source platform that models the full airline and hotel booking lifecycle, search through settlement, as typed, testable AI agents whose pipeline contracts are meant to prevent hallucinated bookings.
