#rest

Posting Board

API-only bulletin board where AI agents post findings and coordinate with each other, no human UI

phpEZ

A tiny, single-file PHP framework for building REST APIs on cheap shared hosting, without Composer, build steps, or thousands of framework files.

Lumify

Lumify is a real-time sports data and odds API purpose-built for AI agents and autonomous trading/betting systems, rather than human dashboards.

Routebase

An API platform where a single OpenAPI spec drives design, mock servers, automated tests, and auto-updating documentation.

xh

A command-line tool for testing APIs that reads almost like plain English (`xh get example.com`), built to start faster and run lighter than HTTPie or curl.

SoapUI

A tool that lets developers and testers check whether an API actually works correctly — sending it test requests and verifying the responses — without writing a full test-automation script from scratch.

apiCEP

API that verifies Mexican bank transfer receipts against Banxico records in under 10 seconds, catching fake and edited payments.

Kavo

An open-source library that auto-generates complete REST, GraphQL, and MCP APIs from your existing ORM entities.

Hubble

An API that assembles a patient's full medical record across every provider, using EHR connections plus browser and voice agents as fallback.

Crustdata

A real-time API for company and people data — sales, recruiting and investing teams query it directly, or plug it straight into Claude via MCP, instead of buying a static list that's already stale.

Datahyena

An API that tells you the moment a company raises funding, gets acquired, or hires a new exec — clean, deduplicated data you can plug straight into a CRM instead of building your own company-tracking database.

qAPI

Tests whether your APIs actually work — including the AI-powered ones — without needing someone on the team who can write test-automation code, since it's built to be set up by clicking rather than scripting.

ApyHub

Instead of building and maintaining your own code for boring-but-necessary tasks — converting a file, validating an email, resizing an image — ApyHub gives you over 200 ready-made APIs behind a single login and a single bill.

Firma.dev

A developer API that adds legally-binding e-signatures to any app for a few cents per document, instead of days of DocuSign integration work.

Mireye

API that gives AI agents reliable, sourced facts about any US location — terrain, flood risk, building data — so an agent can answer questions about the physical world instead of guessing.

Requesty

A single API endpoint that talks to 600+ AI models from 30+ providers, so switching from one AI model to another — or spreading requests across several for cost or reliability — doesn't mean rewriting your app's code.

Apiable

A ready-made storefront and billing layer that sits on top of your existing API gateway, so external developers can discover, sign up for, and pay to use your APIs without your team building that portal from scratch.

Thunder Client

Lightweight REST/WebSocket/gRPC API client built into VS Code and JetBrains — no app switching, local-first, git-syncable.

RAML

RESTful API Modeling Language, a simple and succinct way of describing practically-RESTful APIs.

API Blueprint

Tools for your whole API lifecycle. Use it to discuss your API with others. Generate documentation automatically. Or a test suite. Or even some code.
