Quickstart

Get started with Coinlib API in minutes using your preferred integration method.

# Add to your MCP client config (Claude Desktop, Cursor, Windsurf)
{
  "jentic": {
    "url": "https://api.jentic.com/mcp",
    "auth": "oauth"
  }
}

# Then ask your agent:
"get global crypto market overview"

# → Jentic returns the GET /events tool with parameter schema, agent executes.

Jentic publishes the only available OpenAPI document for Coinlib API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Coinlib API, keeping it validated and agent-ready. Coinlib is a compact cryptocurrency data API exposing three endpoints: global market metrics, a paginated coin list with prices and market caps, and a per-coin lookup for detailed metadata. It is suitable for simple price displays, market overviews, and lightweight crypto data widgets.

Use Cases

Patterns agents use Coinlib API API for, with concrete tasks.

★ Crypto Market Overview Widget

Render a market overview widget showing global crypto market cap, total volume, and BTC dominance. The /global endpoint returns the headline numbers in one call, ideal for dashboards and homepages.

Call GET /global with pref=USD and return total market cap, total volume, and bitcoin dominance

Coin Listing Table

Power a sortable table of cryptocurrencies with current price, market cap, supply, and 24-hour change. The /coinlist endpoint returns paginated rows that map directly to a UI table, suitable for explorers and education sites.

Call GET /coinlist with page=1 and return the top coins with price, market cap, and 24h change

Single-Coin Detail Card

Build a coin detail card showing price, supply, market cap, and metadata for one specific coin. The /coin endpoint accepts a ticker symbol and returns the relevant fields in a single response. Useful for coin pages on educational and tracking sites.

Call GET /coin with symbol=BTC and pref=USD and return the price, supply, and 24h change

AI Market Summariser via Jentic

Build an agent that produces brief crypto market summaries using Coinlib through Jentic. The agent expresses an intent (give me a market overview, look up a coin); Jentic resolves the right endpoint and executes the call with stored credentials. Cost-effective for chat assistants that need a one-line market summary.

Through Jentic, fetch global market data and the top three coins by market cap and produce a short summary

Why though Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Coinlib API keys are stored encrypted in the Jentic vault. Agents receive scoped execution tokens — the raw key query parameter is injected server-side at execution and never appears in agent context.

Intent-based discovery

Agents search Jentic by intent (e.g. get crypto market overview) and Jentic returns the matching Coinlib operation with its parameter schema, so the agent calls the correct endpoint without browsing docs.

Time to first call

Direct integration: under an hour for auth and pagination. Through Jentic: under 15 minutes — search, load schema, execute.

FAQs

Specific to using Coinlib API API through Jentic.

Why is there no official OpenAPI spec for Coinlib API?

Coinlib publishes textual API documentation but not a machine-readable OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Coinlib API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.

What authentication does the Coinlib API use?

Coinlib uses an API key passed as the key query parameter on every request. Through Jentic, the key is stored in the encrypted vault and the agent receives a scoped execution token rather than the raw key value.

Can I list cryptocurrencies with prices and market caps using Coinlib?

Yes. GET /coinlist returns a paginated list of coins with current price, market cap, circulating supply, and 24-hour change. Use the page query parameter to walk through results and the pref parameter to choose a quote currency.

What are the rate limits for the Coinlib API?

Coinlib enforces per-key rate limits that vary by plan. The OpenAPI spec does not declare exact thresholds; consult your Coinlib account dashboard for current limits attached to your key.

How do I look up a single coin's price through Jentic?

Install the SDK with pip install jentic, search Jentic for look up a single cryptocurrency price, load the schema for GET /coin, and execute with the symbol (for example BTC) and pref currency (for example USD).

Does Coinlib expose global market metrics?

Yes. GET /global returns total crypto market capitalisation, total volume, and dominance percentages quoted in the preferred currency you supply, suitable for top-of-page market summaries.
