Introducing CurrencyCore

We’ve been building global products for years. Every time we needed currency data, we bolted on the same creaky exchange-rate service: slow response times, opaque pricing, no history worth the name, and nothing built for the way teams work today — AI agents, automation, and global pricing that actually makes sense.

So we built CurrencyCore, a Currency Intelligence Platform for developers, AI agents, and businesses.

More than exchange rates

CurrencyCore brings together the pieces teams usually stitch from three or four vendors:

• REST API, convert any pair of ISO 4217 currencies, pull rate maps, query historical data, and run analytics over a clean, edge-cached API.
• Historical FX, query any past date for auditable, reproducible conversions, backtesting, and reporting.
• MCP server, connect Claude, Cursor, Windsurf, and other AI agents over the Model Context Protocol, included on every plan.
• AI queries, ask currency questions in plain English and get a precise answer backed by live rates, PPP data, and historical intelligence.
• Teams & enterprise, organizations, shared API keys, role-based access, OIDC SSO, and audit logs.

Rates at the edge, intelligence everywhere

Most exchange-rate services are centralized. Your request travels to a single data center, gets processed, and comes back — latency you didn’t need.

CurrencyCore caches rates at the edge across Cloudflare’s global network, so most requests resolve in a single fast round-trip without cold starts. And because the platform layers analytics, PPP, and AI on top of those rates, you’re not just getting a number — you’re getting context.

curl https://api.currency-core.com/v1/convert \
  -H "Authorization: Bearer cc_live_your_key" \
  -G --data-urlencode "from=USD" --data-urlencode "to=INR" --data-urlencode "amount=100"

Historical exchange rates

Need yesterday’s rate, or a rate from a decade ago? Pass a date and get the exact, carry-forward-resolved value — ideal for invoicing, audits, and reproducible analytics over historical FX. The full dataset goes back to 1949 across 160+ currencies.

An MCP server for your AI agents

This is where CurrencyCore is different. We ship a native Model Context Protocol (MCP) server, so AI assistants — Claude, Cursor, VS Code, Gemini — can fetch live rates, convert currencies, and run analysis using your organization’s keys, usage, and limits. No glue code, and it’s on every plan including Free.

Ask currency questions in plain English

Point the /ai endpoint at a natural-language question and get a precise answer backed by live rates, historical series, and PPP data:

curl -X POST https://api.currency-core.com/v1/ai \
  -H "Authorization: Bearer cc_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"q": "How has INR trended against USD this year, and what is the PPP gap?"}'

No parsing, no prompt engineering, one AI credit per query. Currency intelligence on demand.

Built for teams

Invite your team into an organization, share API access without sharing secrets, and assign roles. Larger orgs get OIDC Single Sign-On, audit logs, unlimited seats, and priority support — governance built in, not bolted on.

PPP when you need it

Pricing for a global audience? CurrencyCore applies Purchasing Power Parity (PPP) factors with a single ppp=true parameter, so $29/month feels fair whether your user is in San Francisco or Mumbai. It’s there when you need it, backed by IMF data, updated annually.
