For Agents
Query verified corporate, government, and ETF crypto treasury holdings, prices, historical purchases, and a real-time signals feed. Every holdings figure ships with how it was verified and a source link.
Use for: I need to see which companies hold Bitcoin in their treasury, Get a single holder's crypto treasury detail, List all tracked treasuries, Check the latest token prices
Not supported: Does not handle trade execution, portfolio management, or custody. Use for querying verified crypto treasury holdings, prices, and signals only.
The CorpStacking API reports the Bitcoin, Ethereum, Solana, and XRP treasury holdings of corporate, government, and ETF holders, along with the SEC filings, prices, and historical purchases behind them. It lists tracked treasuries, returns a single holder's detail and purchase history, serves aggregate stats and live token prices, and carries a real-time signals feed over both polling and Server-Sent Events. Every holdings figure ships with how it was verified and a link to its primary source.
Install Jentic One Beta
Connect the CorpStacking API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the CorpStacking 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%2Fcorpstacking.com%2Fcorpstacking" | sh2
Step 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%2Fcorpstacking.com%2Fcorpstacking" | 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.
Capabilities
What an agent can do with CorpStacking API.
Query corporate, government, and ETF treasury holdings of Bitcoin, Ethereum, Solana, and XRP
Retrieve a single treasury's holdings detail and purchase history
Pull aggregate treasury stats across all tracked holders
Read live token prices and global market stats
Stream a real-time treasury signals feed over Server-Sent Events
Subscribe a webhook to treasury activity and inspect its delivery history
Use Cases
Patterns agents use CorpStacking API for, with concrete tasks.
★ Agent-Monitored Treasury Signals
An AI agent connected through Jentic watches the CorpStacking signals feed for new corporate crypto purchases and surfaces each one with the verification method and primary source attached. Because the feed is available over Server-Sent Events, the agent reacts as signals land rather than polling on a timer.
Read the treasury signals feed, pick up a new purchase signal, and return the holder, token, and the primary source link behind it
Corporate Crypto Holdings Research
A research workflow pulls the full list of tracked treasuries and then the detail and purchase history for a specific holder, grounding each figure in the SEC filing or source CorpStacking verified it against. This replaces hand-collecting disclosures with a single queryable dataset of who holds what.
List tracked treasuries, fetch one holder's detail by slug, and report its current holdings and most recent purchase
Market Price Context
An analytics job reads live token prices and global market stats alongside the holdings data, so a treasury's position can be valued at current prices in the same integration. The market endpoint keeps price context next to the holdings rather than wiring a separate price source.
Read live token prices and combine them with a holder's reported holdings to estimate the position's current value
Key Endpoints
16 endpoints — the corpstacking api reports the bitcoin, ethereum, solana, and xrp treasury holdings of corporate, government, and etf holders, along with the sec filings, prices, and historical purchases behind them.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the CorpStacking API by hand means sending the x-api-key header on every call, handling its wrapped data-and-meta JSON responses, and treating the raw exports and event stream differently from the JSON endpoints. Through Jentic you install once, import CorpStacking from the API Directory, store the key once, and your agent calls it.
Permission scoping
CorpStacking puts the treasury slug in the URL path (/treasuries/{slug}), so a rule can pin your agent to one treasury and the operations you pick, such as reading its holdings and activity. You choose the operations it may call, so the webhook-delete operation is not included unless you add it.
Credential isolation
Your CorpStacking API key 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 'which companies hold Bitcoin' or 'latest crypto treasury signals', and Jentic returns the matching CorpStacking operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using CorpStacking API through Jentic.
What authentication does the CorpStacking API use?
The CorpStacking API authenticates with an API key sent in the x-api-key header per its OpenAPI spec, and a key in the query string is not accepted. Through Jentic the key is stored encrypted by your own Jentic One instance and injected at call time, so it never reaches the agent's context.
Can I query a single company's crypto treasury holdings with the CorpStacking API?
Yes. Fetch a holder by its slug to get the treasury detail and purchase history, with every holdings figure carrying how it was verified and a link to its primary source. The list endpoint returns all tracked corporate, government, and ETF holders to pick from.
Can I limit what my agent is allowed to do with the CorpStacking API?
Yes. Write a rule that allows only the read operations, such as listing treasuries, reading a holder's detail, and the market and signals feeds, so your agent can research holdings but cannot create or delete webhook subscriptions, and every call it makes is logged.
What are the rate limits for the CorpStacking API?
The CorpStacking API exposes a usage endpoint that returns your current rate limit and quota, so your agent can read its own ceiling at runtime; the OpenAPI spec does not hard-code a numeric figure. Check the usage endpoint for the limit that applies to your key.
How do I find which companies hold Bitcoin with the CorpStacking API through Jentic?
Search Jentic for 'which companies hold Bitcoin in their treasury' and it returns the treasuries-listing operation with its input schema; your agent filters by token and reads each holder's detail. To run it on your own infrastructure, install Jentic One from its GitHub repo.
Is there a CorpStacking MCP server?
You don't need an MCP server to give your agent the CorpStacking API. Jentic connects it directly from the API Directory: import it, store your key once, and your agent calls the holdings, market, and signals operations with scoping and credential isolation applied.
