DataXAPI MCP server: market data in your AI, connected with one prompt

Copy one prompt with your key in it, paste it into your agent, and ask. It reads one page and sets itself up: 5 tools, 207 endpoints on 21 platforms, from $0.0003 a call, and a failed call is never charged.

Just ask

Your AI finds the endpoint with find, runs it with call and answers with links. Every call is in the console's call log.

More questions

Prefer to do it by hand?

Every client connects to the same address, the key in a header. Give that key a daily spending limit, so a few extra calls cannot run past it.

What a session looks like

You ask in plain words. The AI does the rest by itself, and tells you what it spent.

It searches before it calls.

No endpoint names to remember.

find · Free

It sees the price first.

And can set the most it will pay for the call.

describe · Free

It gets an answer that fits.

Compact by default and cut at about 20 KB; read_more reads the rest at no charge.

call · $0.0020

It shows the bill.

Three tool calls, one charged.

3 tool calls · 1 charged · $0.0020

You set the limits

An AI that can spend needs a ceiling. There are three, and the server enforces them.

A spend limit on every key

Give your AI its own key with a daily, monthly or total budget. When it is used up, calls stop. Nothing else on your account is touched.

A ceiling on every call

With max_price, a call that could cost more is refused before anything is charged. A call that is sent twice with the same idempotency_key is charged once.

max_price: "0.01" · nothing if the call fails

Read-only, public data

DataXAPI reads what anyone can see on the platform. It cannot post, message, sign in to an account or change anything.

4 of 5 tools marked readOnly

Questions

Before you connect.

What does it cost?

Connecting is free. Searching the catalog, reading an endpoint, re-reading a result and checking your account are free. A call costs the endpoint's listed price, from $0.0003, and nothing if it fails.

Do I need to install anything?

No. It is a remote server at one address. dataxapi setup only writes the entry into your client's configuration (Claude Code, Cursor, Codex) and installs the base skill; the prompt lets your agent do that for you.

Can my AI spend money without asking me?

call is not marked read-only, so a client that asks before running such tools will ask. Either way, the key's budget is the hard stop.

Will new platforms need a new server?

No. The 5 tools stay the same; a new endpoint shows up in find the day it ships.

What if an answer is too long for the context?

An answer is cut at about 20 KB, on an item boundary, and says how to read on. read_more reads the rest for 24 hours at no charge.

Does it work in ChatGPT, Claude?

Yes, on the web and in the desktop apps: add a custom connector with the address https://api.dataxapi.com/mcp. No key is typed in: you are asked to sign in to DataXAPI and approve, and there you choose the key its calls are charged through and that key's spending limit. ChatGPT: Settings → Apps & Connectors → turn on developer mode under Advanced → Create a connector: the MCP address, with OAuth as its authentication. Claude: On the web or in the desktop app: Settings → Connectors → Add custom connector, with the MCP address.

Connect once. Ask about any market.
