APIs.io Blog

For most of the last decade the command line was a stable, slightly boring corner of the developer toolchain. Then Claude Code, Cursor, and OpenAI Codex showed up, and the CLI is suddenly the most contested surface in...

Cloudflare started as a CDN and DNS provider. Fifteen years later, the developer surface looks nothing like a CDN — it’s a full-stack edge platform spanning serverless compute, AI inference, vector search, object stor...

Below the MCP surface and the skill bundle, there is a runtime layer — agent frameworks, agent SDKs, agent gateways, and the orchestration primitives that hold the whole stack together. The week of May 4-8, 2026 produ...

tags.apis.io is the cross-network tag index. Every provider, API, capability, schema, AsyncAPI spec, JSON-LD context, and Spectral ruleset in the catalog can be tagged, and the tag index aggregates those tags across t...

If MCP is the surface that defines what tools exist, skills are the layer that defines how to use those tools well. The week of May 4-8, 2026 produced fewer skill-related stories than MCP-related ones (8 vs 31), but t...

The week of May 4-8, 2026 produced 31 distinct stories across the API Evangelist network about Model Context Protocol — vendors shipping servers, building gateways, writing how-to guides, hardening the auth and testin...

The APIs.io network just grew by three sites. Pricing plans, rate limit policies, and FinOps profiles — three of the most operationally important pieces of metadata about an API, and three that have historically been ...

The capabilities count on capabilities.apis.io crossed 2,136 capabilities in this morning’s rebuild — a +767 jump from yesterday. That number deserves more than a stats-bump update because each of those capabilities i...

When you think of payments APIs, the names that come up first are usually the modern fintech entrants — Stripe, Plaid, Adyen. The card networks that move the actual money tend to sit one layer beneath that conversatio...

The APIs.io network ingests blog posts from every API-bearing provider it indexes. Last week (Apr 26 → May 3) the feed pulled in 2,104 posts across 884 producers, of which 178 carried API-relevant signals in the title...

Most of what gets profiled in the catalog is request/response — REST APIs documented with OpenAPI. But a growing slice of the network is the other half of the integration story: events, webhooks, message queues, and s...

The April profiling batch just landed and the numbers are substantial. This rebuild added 609 providers and 1,951 APIs to the catalog, pushing the total API count past 10,000 for the first time — 10,360 APIs across 2,...

The APIs.io catalog now indexes 750 capabilities across hundreds of providers. That number is easy to scroll past without understanding what it means, because “capability” sounds like a synonym for “API.” It isn’t. A ...

The APIs.io catalog added another 245 providers and 599 APIs in a second rebuild cycle today, pushing the running totals to 1,944 providers and 8,409 APIs — the first time the network has crossed 8,000 APIs. The /.wel...

The APIs.io catalog grew by 235 providers and 717 APIs in this rebuild — the largest single-cycle expansion since the agent-readiness work shipped two weeks ago. The running totals now sit at 1,699 providers and 7,810...

HubSpot is one of the wider provider profiles in the APIs.io catalog — wider than most because the platform has grown well past its CRM origins and now spans marketing, content, commerce, customer service, and a devel...

The APIs.io catalog grew by 102 providers and 345 APIs this morning — the largest single network refresh since automatic rebuild posts began. The newly profiled entries push the running totals to 1,464 providers and 7...

APIs.io has always been a directory of APIs. Over the last two weeks the directory itself became a consumable interface — built so an AI agent can discover, evaluate, and integrate with any of the 7,000+ APIs and 1,40...

APIs.io has always been about making APIs discoverable by machines. The APIs.json format provides a machine-readable index of what APIs exist and where to find them. That solves the discovery problem for APIs themselv...

I recently profiled the Federal Bureau of Investigation (FBI) Most Wanted API. There are additional APIs to be profiled, but I wanted to get this one in the system so we could use as part of other work. One thing I t...

I recently profiled the Wolfram Alpha LLM API. There are additional APIs to be profiled, but I wanted to get this one in the system so we could use as part of other work. One thing I tested with this one was the abil...

I profiled the InfluxDB time series API. Their cloud API is the one I profiled, and there may be other opportunity to profile their other API offerings. I was able to find the documentation and an OpenAPI, as well as ...

I recently profiled the Moody’s KYC API, which was an acquisition they made of Kompany.com. I was able to find the documentation and an OpenAPI, which I added as API properties. I profiled many common properties incl...

APIs.io is all about redefining what API search is. Since we created APIs.json and APIs.io back in 2014 numerous API catalogs, directories, and networks have either disappeared or gone dormant. API discovery is hard t...
