|---|---|---|---|---|
contact_chainstackSubmit a message to Chainstack's sales and support team.
Use when the user wants to ask about pricing, get a custom quote,
request a plan upgrade, request node customizations (Enterprise),
report a problem, or reach Chainstack for any reason. Posts to the
same contact form as chainstack.com/contact/.
## Before calling this tool
CRITICAL — follow these steps EVERY time:
1. Draft the message based on your conversation context.
2. Show the user the EXACT message, email, and name you will send.
3. If the user has a Chainstack API key configured, tell them their
org name and ID will be included so the team can find their
account and reply faster.
4. Ask: "Shall I send this to Chainstack? Please confirm there's
no sensitive information you'd like removed."
5. Only call this tool after the user explicitly confirms.
NEVER include in the message:
- API keys, tokens, passwords, private keys, wallet seeds, mnemonics
- RPC endpoint URLs (Chainstack or any other provider)
- Wallet addresses, transaction hashes, on-chain account details, or
anything else the user hasn't explicitly approved sharing
## Writing an effective message
Include what you know: what they're building and at what scale,
current plan and usage, what they need, what they've tried, and
specific numbers.
Bad: "I have a question about pricing."
Good: "Pro plan user running 200M RU/month across Base and Ethereum,
evaluating Business plan for archive access and higher RPS.
Looking for annual pricing or a trial."

Works with or without an API key; with one, the org info is attached. | Yes | No | No | Yes |
create_nodeDeploy a new blockchain node. Call get_deployment_options first for valid IDs.
Use a Global option (node_tier "Global") from get_deployment_options. | No | No | No | Yes |
create_node_access_ruleAdd an IP or Origin allowlist rule to a Global node.
New rules are deactivated and do nothing until activated. Active IP rules
limit which client IPs can call the node; active origin rules limit which
Origin headers it accepts. With both kinds active, a request must pass
both. Everything else gets HTTP 403 within about 10 seconds. Rules don't
affect the Chainstack API, so they can always be changed or deactivated
with these tools.
Before activating, confirm with the user that the IP rules cover every IP
that calls the node (servers, CI, their own machine); you can't check
this. Origin rules are for browser-only access: once one is active, every
request without an Origin header (servers, scripts, curl) is blocked, even
from an allowed IP.
If an identical rule exists, it is returned instead of a duplicate. | Yes | No | No | Yes |
create_projectCreate a new project. | No | No | No | Yes |
delete_nodeDelete a node (irreversible). | Yes | No | Yes | Yes |
delete_node_access_ruleDelete an access rule from a node (irreversible).
Deleting an active rule changes who can reach the node; the result says
what's enforced afterwards. With no active rules left, the node accepts
requests from any IP and origin. | Yes | No | Yes | Yes |
delete_projectDelete a project (irreversible). | Yes | No | Yes | Yes |
get_chainstack_pricingFetch Chainstack's public pricing and return a normalized snapshot.
Use this to answer pricing questions before quoting the user: plan fit,
overage math, per-chain dedicated-node costs, and add-on pricing
(Unlimited Node flat-fee tiers, Yellowstone gRPC streams, Warp
transactions, dedicated-node base rates).
This tool returns the menu, not the bill — the calling agent does the
arithmetic. All prices are list prices in USD; disclaimers are surfaced
in the `disclaimers` field.
Per-method RU billing rules are NOT in these sources. Plan-level rates
(Full Node = 1 RU, Archive Node = 2 RU) are in the markdown, but some
EVM archive-state methods (eth_getBalance, eth_call, eth_getProof,
eth_getStorageAt, eth_getCode, eth_getTransactionCount, eth_callMany,
eth_createAccessList) and all debug_* / trace_* methods are billed at
2 RU on a full node when called against old blocks. For method-level
detail, call `search_docs` with "request units" or
`get_doc_page("docs/request-units")`.
No API key required — sources are fully public. Each call fetches both
sources fresh (no caching), so a stale result isn't possible.
Returns:
A dict with fields:
- `pricing_markdown`: raw markdown from chainstack.com/pricing.md.
Read this for plan tiers, feature matrix, add-on pricing, support
levels, PAYG details, and provider comparisons.
- `dedicated_catalog`: user-orderable per-chain dedicated-node SKUs
with flavor, regions (as infra slugs like "sgp1"), hourly and
monthly prices in USD.
- `region_legend`: slug → city name for every region slug in
`dedicated_catalog`; use it for display.
- `disclaimers`: list-price caveats (Enterprise "from" pricing, etc.).
- `sources`, `warnings`: per-source status; warnings are set when a
source failed and the result is best-effort.
- `fetched_at`: UTC timestamp of this call. | No | Yes | Yes | No |
get_deployment_optionsList blockchain/cloud/network combinations for node deployment.
Call before create_node to get valid blockchain and cloud IDs. | No | Yes | Yes | No |
get_doc_pageGet the full content of a Chainstack documentation page.
Use after search_docs to fetch the complete page when a snippet isn't enough. | No | Yes | Yes | No |
get_nodeGet a node's full details including endpoints and cloud info. | No | Yes | Yes | Yes |
get_organizationGet organization name and ID. | No | Yes | Yes | Yes |
get_platform_statusCheck platform status, active incidents, and maintenances. | No | Yes | Yes | No |
get_projectGet project details. | No | Yes | Yes | Yes |
list_node_access_rulesList a node's access rules (IP and Origin allowlists, Global nodes only).
With no active rules, the node accepts requests from any IP and origin.
If correctly configured rules still return 403, that's a support case:
offer contact_chainstack. | No | Yes | Yes | Yes |
list_nodesList nodes with status and connection endpoints. | No | Yes | Yes | Yes |
list_projectsList all projects. Projects are containers for nodes. | No | Yes | Yes | Yes |
request_testnet_fundsTop up a testnet address from Chainstack's faucet.
The faucet does not send a fixed amount — it tops the address up to the
per-network maximum (e.g. 0.5 ETH for sepolia). If the address already
sits above the cap, the call fails with an insufficient-balance error.
Describe the behavior to the user as "top up" not "give", and surface
the returned `amountSent` so they see the actual delta.
One top-up per network every 24 hours: a repeat call for the same network
is refused (429) if the same organization or the same address got funds
there in the last 24 hours, and the error says when the next top-up is
available. Other networks have separate cooldowns. A success is final even
if the balance hasn't updated yet; track the returned `transaction`
instead of calling again. | Yes | No | No | Yes |
search_docsSearch Chainstack docs — blockchain RPC methods, node infrastructure, Web3 APIs, deployment guides, and code examples. | No | Yes | Yes | No |
set_node_access_rules_statusActivate or deactivate every access rule on a node at once.
Activating enforces every rule within about 10 seconds: active IP rules
limit which IPs can call the node, active origin rules limit which Origin
headers it accepts, and a request must pass both kinds. Others get HTTP
403. First confirm with the user that the IP rules cover every IP that
calls the node (servers, CI, their own machine); you can't check this.
Origin rules block every request without an Origin header (servers,
scripts, curl), even from an allowed IP. Deactivating opens the node to
any IP and origin. | Yes | No | Yes | Yes |
update_nodeRename a node. | Yes | No | Yes | Yes |
update_node_access_ruleChange an access rule's value, or activate or deactivate it.
A rule's type can't change; delete it and create a new one. Before
activating, confirm with the user that the IP rules cover every IP that
calls the node. Activating the first origin rule blocks every request
without an Origin header (servers, scripts, curl), even from allowed IPs.
Changing or deactivating a rule can block clients that only it allowed. | Yes | No | Yes | Yes |
update_projectUpdate a project's name or description. | Yes | No | Yes | Yes |
