Read chain state and pay per request: blockchain infrastructure for AI agents

AI agents read state, sign transactions and pay for what they use without a human in the loop. Instanodes gives them RPC data they can parse, an MCP server for Claude Code, Cursor and Codex, and wallet-signed payments so an agent can pay per request without an API key. Available across 50+ networks.

Networks: 50+; One RPC API for every chain an agent reads
Shared p99: <100ms; Globally distributed RPC Endpoints
Free requests: 600K; Per month, enough to build and test
Uptime SLA: 99.95%; Contractual, with automated failover

Where an agent plugs in

Data for reading state, tooling for the coding assistant that writes the integration, and payments for an agent that settles its own requests.

Data Layer

Read blockchain data

Query and stream chain data over JSON-RPC and WebSockets, with gRPC streams and webhooks on supported chains. Structured responses an agent can parse without scraping.

eth_getBalance(address, "latest")
eth_getLogs({ address, topics })
eth_subscribe("newHeads")

Development Layer

Build with AI coding assistants

Connect Claude Code, Cursor, Codex or any MCP-compatible assistant to Instanodes, and it writes blockchain integrations against real endpoints and methods.

1  Install the Instanodes MCP server
2  Describe your application
3  Generate integration code
4  Run and iterate

Execution Layer

Execute onchain actions

Agents pay for requests with wallet-signed stablecoin payments, sign transactions and call smart contracts, with no API key to provision.

request   → 402 Payment Required
sign      → stablecoin payment
retry     → 200 OK

What teams point agents at

Agent workloads run on the same RPC Endpoints and nodes as any other application.

Research that reads the chain

Agents that read balances, positions and events across 50+ networks as blocks land.

Trading and DeFi bots

Agents that watch pools and submit transactions, reading at <100ms p99.

An appchain of its own

Give an agent dedicated blockspace on an appchain, with gas and throughput you set.

Agents that watch infrastructure

Agents that track validators, nodes and uptime, and open an alert or act when something drifts.

Give your agent an endpoint today

The free tier covers 600K requests a month across 50+ networks, enough to build and test an agent before it touches real funds.
