Each provider is represented as a GitHub repository containing an apis.yml file in APIs.json format (v0.19), which serves as a machine-readable profile declaring identity, API entries, and standardized property types like OpenAPI specs, Plans, RateLimits, and FinOps data. The catalog has indexed 10,754 OpenAPI specs and 14,123 unique tags. The APIs.json standard provides a shared vocabulary that eliminates the need for custom parsers per provider, enabling governance queries across the entire dataset. The GitHub repos feed APIs.io, a search and discovery layer. Using GitHub as storage provides version history, programmatic access via API, and community editability through pull requests. 112 3 2. 2 [](https://daily.dev/posts/standalone-json-schemas-overlaid-for-every-purpose-bnhnsyrzz "Standalone JSON Schemas, Overlaid for Every Purpose") Article API Evangelist·10w Standalone JSON Schemas, Overlaid for Every Purpose Rather than embedding data models inside an OpenAPI document's \`components.schemas\`, this post advocates for standalone JSON Schema files with their own \`$id\` in a dedicated \`schema/\` directory. Each schema file becomes a reusable asset consumed by multiple systems — API validation, code generation, documentation, and data warehousing — without being locked to a single OpenAPI document. OpenAPI overlays can then be applied to these standalone schemas for locale-specific or audience-specific purposes (e.g., translating only \`description\` fields into German), keeping structural truth in the base schema and presentation concerns in the overlay. The core argument: schemas describe things, not APIs, and things outlive the APIs that move them. 27 1 3. 3 [](https://daily.dev/posts/your-diverse-api-toolbox-2grqiu6u1 "Your Diverse API Toolbox") Article API Evangelist·12w Your Diverse API Toolbox A practitioner's argument for maintaining a diverse API toolbox rather than chasing any single dominant pattern. Covers REST, GraphQL, gRPC, Webhooks, WebSockets, Kafka, MCP, and Agent Skills — explaining when each belongs in your architecture. Also addresses experience patterns (documentation, mock servers, discovery), integration patterns (clients, SDKs, AI copilots, agents), media types, and API specifications (OpenAPI, AsyncAPI, JSON Schema, Protocol Buffers). The core thesis: MCP and Agent Skills extend the toolbox, they don't replace the foundation. Practitioners who understand tradeoffs outperform those who follow hype cycles. 11 4. 4 [](https://daily.dev/posts/the-apis-of-the-world-s-top-universities-634-of-them-and-most-are-library-plumbing-o5ephklbs "The APIs of the World's Top Universities — 634 of Them, and Most Are Library Plumbing") Article API Evangelist·13w The APIs of the World's Top Universities — 634 of Them, and Most Are Library Plumbing A survey of 219 top-ranked universities (QS 2025) uncovered 634 APIs across 40 countries, but 84% of them are OAI-PMH institutional repository endpoints — metadata harvesting plumbing bundled with platforms like DSpace, EPrints, and Figshare. Only 16% of schools run anything resembling a modern developer program with portals, OAuth, or open-data APIs. Standouts include UCL (student-built OAuth portal), University of Pennsylvania (SDKs in Python and Node), and UC Berkeley (API Central gateway). Notable outliers include Caltech's astronomy Virtual Observatory APIs, Shanghai Jiao Tong's GraphQL endpoint, and ETH Zurich's library-as-data-platform approach. The core finding: universities have enormous structured open research data but almost no developer-facing front door to it. 11 1 [See all API Evangelist archives](/sources/apievangelist/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/apievangelist/best-of/2026/06#page","url":"https://daily.dev/sources/apievangelist/best-of/2026/06","name":"Best API Evangelist Posts — June 2026","description":"The most upvoted API Evangelist posts from June 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/apievangelist/best-of/2026/06#items","numberOfItems":4,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/the-architecture-behind-10-000-api-providers-53q1xhtyw","name":"The Architecture Behind 10,000 API Providers"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/standalone-json-schemas-overlaid-for-every-purpose-bnhnsyrzz","name":"Standalone JSON Schemas, Overlaid for Every Purpose"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/your-diverse-api-toolbox-2grqiu6u1","name":"Your Diverse API Toolbox"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/the-apis-of-the-world-s-top-universities-634-of-them-and-most-are-library-plumbing-o5ephklbs","name":"The APIs of the World's Top Universities — 634 of Them, and Most Are Library Plumbing"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"API Evangelist","item":"https://daily.dev/sources/apievangelist"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/apievangelist/best-of"},{"@type":"ListItem","position":5,"name":"June 2026"}]}]} ```
