Why use Ceven?

  1. AI native Polygon integration

    • Describe the outcome and Ceven picks the right Polygon calls, fills the parameters, and checks the result.
    • Structured, agent friendly tool schemas so each call runs reliably instead of by guesswork.
    • Rich coverage for reading, writing, and querying your Polygon data, across all 90 of its actions.

  2. Managed auth

    • Built in OAuth with automatic token refresh and rotation.
    • One place to manage, scope, and revoke Polygon access.
    • Per user and per environment credentials instead of shared keys.

  3. Agent optimized design

    • Actions are tuned from real success and error rates so reliability climbs over time.
    • Full execution logs so you always know what ran in Polygon, when, and on whose behalf.
    • The agent pauses and asks when Polygon is unclear instead of plowing ahead.

  4. Enterprise grade security

    • Fine grained access so you control which agents and people can reach Polygon.
    • Least privilege by default, read scopes first and only the writes a workflow needs.
    • A full audit trail of every Polygon action to support review and sign off.

Frequently asked questions

Ceven implements a sophisticated queuing system that respects the specific tier of your Polygon account. If you are on a free tier, the agent automatically throttles requests to stay within the five calls per minute limit to avoid 429 errors. For paid tiers, Ceven optimizes requests by batching ticker lookups and caching static reference data like exchange lists. If a rate limit is hit, the agent uses an exponential backoff strategy, pausing the workflow and retrying the request once the window resets. You can see the current consumption and any throttling events in the workflow execution logs.
Ceven acts as the intelligence and orchestration layer. While Polygon provides the high fidelity data and indicators needed to make a decision, Ceven does not execute trades directly on an exchange. Instead, you build a workflow where Polygon provides the signal, and Ceven then pushes that signal to a trading platform via API or sends a notification to your terminal. For example, if a Polygon RSI indicator drops below 30, Ceven can trigger a webhook to your brokerage or alert your trading desk via Slack with the supporting data attached.
The latency depends entirely on your Polygon subscription plan. Users with a basic or free plan receive delayed data as per Polygon terms. For those with a professional or enterprise subscription, Ceven accesses the real time WebSocket and REST endpoints. Because Ceven processes these events in a serverless environment, there is a negligible overhead of a few milliseconds added to the raw API response time. This makes it suitable for swing trading and portfolio rebalancing, though it is not designed for high frequency trading where microsecond latency is the primary requirement.
Yes, Ceven can interact with stocks, options, forex, and cryptocurrencies. The agent is programmed to recognize which tool to use based on the ticker symbol provided. If you ask for a crypto indicator, it automatically routes the request to the crypto specific EMA or RSI tools. If you ask for dividends, it uses the stock specific endpoints. This means you can build cross asset workflows, such as monitoring the correlation between Bitcoin price movements on Polygon and the stock price of Coinbase in a single automated sequence.
Ceven does not calculate indicators locally. It leverages Polygon's server side technical indicator endpoints. When you request an SMA or EMA, Ceven sends the ticker, window size, and timespan to Polygon, and Polygon returns the computed value. This ensures that the math is consistent with professional charting software and reduces the amount of raw data that needs to be transferred to the workflow. This approach also allows the agent to pull pre computed historical indicator values for backtesting without needing to download years of minute by minute price data.
Ceven manages watchlists within the workflow state rather than on Polygon servers. You can define a list of tickers in a Ceven variable or a connected Google Sheet, and the agent will iterate through that list using Polygon tools to check for specific conditions. For instance, you can tell the agent to check the previous close for every ticker in your growth portfolio every morning at 8 AM. The agent handles the looping and individual API calls, aggregating the results into a single report for your review.
When a ticker is delisted or undergoes a symbol change, Polygon returns a specific error or an empty response. Ceven is designed to handle these gracefully by flagging the ticker as invalid in your workflow logs. If you are using the Get Ticker Details tool, the agent can detect changes in the company name or identifiers. You can build a cleanup workflow that periodically runs the Get All Tickers tool to reconcile your internal watchlists against the current Polygon universe, ensuring you are not wasting API calls on dead symbols.
Ceven stores your Polygon API key in an encrypted vault. The key is never exposed in the clear to the model or stored in the workflow definition itself. When an action is triggered, the system injects the key into the request header at the infrastructure level. Access to this secret is restricted to the execution environment. You can rotate your key in the Polygon dashboard at any time and update it in the Ceven integration settings, which immediately updates all active agents without requiring you to rewrite your workflows.
