Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

call

call_feed

Call a feed endpoint through the gateway with your API key (or an x402 payment). Without either it returns the 402 payment options.

discover

discover

Search all feeds for endpoints matching a need. Returns up to `limit` ranked endpoints with price, params and latency (`latency.by_region`: cache-miss ms per Cloudflare region).

feeds

list_feeds

List all live feeds with endpoint counts, per-call price range, plans and their paid MCP URL.

free

create_free_key

Create a free API key (1,000 calls/month, all feeds) for the user's real email. Works at once; signing in at realtimeapi.ai with that email later re-issues the secret once.

quote

get_quote

Price an endpoint without calling it: x402 `accepts` for one call plus time-pass plans. Nothing is charged.

sample

get_sample

Free trimmed sample of an endpoint's real response from the probe's cached copy (no key, no payment): see the data shape before paying. Works for results discover marks sample: true.

RealtimeAPI.ai — questions

Answers built from our own checks of this server.

What can RealtimeAPI.ai do?

It exposes 6 tools, read directly from the server on our last check. Among them: call_feed, create_free_key, discover, get_quote, get_sample, list_feeds. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is RealtimeAPI.ai working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 63 of 63 checks got a reply (100.0%), average response time 386 ms. The bar chart above shows every period we have measured.

How do I connect RealtimeAPI.ai?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does RealtimeAPI.ai need an API key?

No. RealtimeAPI.ai completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is RealtimeAPI.ai?

It answers our handshake in 386 ms on average, which is faster than 34% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
