For Agents

Look up current crypto prices, market caps, and global market metrics across thousands of coins via three simple Coinlib endpoints.

Install Jentic One Beta

Connect the Coinlib API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Coinlib API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with Coinlib API.

Retrieve aggregated global crypto market data including total market cap and volume

List coins with prices, market cap, supply, and 24-hour change in a paginated feed

Look up a single coin by symbol with detailed pricing and metadata

Use Cases

Patterns agents use Coinlib 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

Key Endpoints

3 endpoints — jentic publishes the only available openapi specification for coinlib api, keeping it validated and agent-ready.

Why 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 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.
