Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Crypto Vision News 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://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcryptocurrency.cv%2Fcrypto-vision" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcryptocurrency.cv%2Fcrypto-vision" | sh
jentic register # connects your agent to your Jentic One instanceJentic 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.
What an agent can do with Crypto Vision News API.
Retrieve coin market data with filtering, and top gainers and losers
Read Bitcoin and altcoin market dominance
Pull exchange and derivatives market data
Read DeFi statistics such as stablecoins and yields
Generate a daily AI crypto news brief and article summaries
GET STARTED
Track upcoming airdrops and manage price alerts
Patterns agents use Crypto Vision News API for, with concrete tasks.
★ Agent market briefing
An AI agent connected through Jentic reads coin market data and the AI-generated daily brief to produce a morning crypto summary for a user. Many market data endpoints are public, so the agent can gather prices and dominance without a key and only authenticate for premium endpoints.
Read the coin market data and today's AI brief, then write a short market summary with the top gainers
DeFi monitoring
A research workflow pulls DeFi statistics such as the market summary, stablecoin supply, and yield data to track protocol health over time. Crypto Vision exposes separate DeFi endpoints for summary, stablecoins, and yields so an agent can assemble a DeFi snapshot on a schedule.
Read the DeFi summary and stablecoin data and report total stablecoin supply and the top yields
Airdrop and alert tracking
An agent lists upcoming and active airdrops and sets price alerts so a user is notified when a coin crosses a threshold. The airdrops and alerts endpoints let the agent surface opportunities and register watch conditions from the same API.
List active airdrops and create a price alert for a chosen coin at a target price
467 endpoints — the crypto vision news api returns cryptocurrency market data and news across a large surface: coin market data with filtering, top gainers and losers, market dominance, exchange and derivatives data, and defi statistics such as stablecoins and yields.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Crypto Vision News API by hand means handling two auth paths, an X-API-Key header and the x402 micropayment flow, and sorting public market endpoints from paid ones. Through Jentic you install once, import Crypto Vision from the API Directory, store any key once, and your agent calls it.
Permission scoping
Crypto Vision carries each data topic in the URL path, so rules bound which operations your agent may call. You choose the operations it may call, so it can read coin market data and the brief without being able to create alerts or hit paid endpoints unless you add those.
Credential isolation
Any Crypto Vision key you use is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'get crypto market data' or 'get a news brief', and Jentic returns the matching Crypto Vision operation with its input schema so the agent calls the right endpoint without browsing the reference docs.
Alternatives and complements available in the Jentic catalogue.
Specific to using Crypto Vision News API through Jentic.
What authentication does the Crypto Vision News API use?
The Crypto Vision News API accepts an X-API-Key header for authenticated access, and it also supports a pay-per-request x402 micropayment through the X-PAYMENT header, per its OpenAPI spec. Many market data endpoints are public and need no credential. Through Jentic any key you use is stored once by your own self-hosted instance and injected when a call runs, so it never appears in the agent's prompt or logs.
Can I get crypto market data with the Crypto Vision News API?
Yes. Read coin market data with filtering, top gainers and losers, market dominance, and exchange and derivatives data, plus DeFi statistics such as stablecoins and yields. Many of these market endpoints are public, so an agent can pull them without a key.
Can I limit what my agent is allowed to do with the Crypto Vision News API?
Yes. Write a rule that allows only the data operations the agent needs, such as reading coin market data and the daily brief, so it cannot create alerts or spend on paid endpoints, and every call it makes is logged. Add more operations only when the task requires them.
What are the rate limits for the Crypto Vision News API?
The OpenAPI spec does not state fixed rate limits, since paid endpoints are metered through the x402 micropayment model. Check the Crypto Vision documentation for current limits and per-request pricing before heavy use.
Is there a Crypto Vision MCP server?
You don't need an MCP server to give your agent the Crypto Vision News API. Jentic connects it directly from the API Directory: import it, store any key once, and your agent calls the market and news operations on demand without loading another server's tool definitions into its context.
How do I get a crypto brief with the Crypto Vision News API through Jentic?
Search Jentic by intent such as 'get a daily crypto news brief', and Jentic returns the brief operation with its input schema so your agent calls it and reads back the summary. To run it on your own infrastructure, install Jentic One from its GitHub repo.
For Agents
Retrieve cryptocurrency market data, news, and DeFi statistics, with AI briefs and summaries over the news. Many market endpoints are public; others take an API key or an x402 micropayment.
Use for: Get the market data for the top coins right now, Show today's biggest crypto gainers and losers, Check Bitcoin dominance in the market, Pull a DeFi summary with stablecoin supply
Not supported: Does not execute trades, custody funds, or manage wallets. Use for reading cryptocurrency market data, news, DeFi statistics, and on-chain analytics only.
The Crypto Vision News API returns cryptocurrency market data and news across a large surface: coin market data with filtering, top gainers and losers, market dominance, exchange and derivatives data, and DeFi statistics such as stablecoins and yields. It layers AI analysis over the news, including daily briefs, summaries, and named-entity extraction, and tracks airdrops and price alerts. Many market data endpoints are public, while other endpoints accept an X-API-Key header or a pay-per-request x402 micropayment. It reports data only and does not place trades or move funds.
