Circuit SDK node — join/manage a mesh node from code: the inference-mesh control plane (register/ready/heartbeat) + the public node registry (announce/ping). The heavy GPU serving stays in the node image.

Circuit SDK models — client for the circuitllm.xyz/models gateway: buy prepaid credits in USDC/SOL/CIRC, mint a Circuit API key, and call the metered OpenAI-compatible chat API.

Tiny, Elegant, and Brutally Optimized HTTP Client for Server-Side Runtimes. Zero-dependency.

Drop-in adapters that expose the Circuit Data API (pay-per-call in CIRC via x402) to agent frameworks: an ElizaOS plugin and a Solana Agent Kit action set. One dependency turns any agent into a Circuit data consumer.

Circuit SDK vault client — drive the non-custodial on-chain Agent Vault Anchor program: owner lifecycle, the route-agnostic trade adapter, a Jupiter route source, and makeVaultExecutor (the concrete executor for @circuit-llm/agent's VaultCustody). Opt-in:

No description provided.

Circuit SDK agent runtime — write an autonomous agent (CircuitAgent) with pluggable custody (paper · self-custody · off-box signer · non-custodial vault). Buy/sell only; on the mesh the key stays off-box, so funds can't leave.

External service integrations, Stripe (payment processing + circuit breaker) and email (Gmail API delivery). Ships with RevealUI.

Neural router for AI agent orchestration - FastGRNN-based intelligent routing with circuit breaker, uncertainty estimation, and hot-reload

Circuit MCP — real-time Solana data, agent-swarm intelligence, and decentralized LLM inference as x402-paid tools for any AI agent. No API keys.

o1js rules for ESLint

Evaluate code in a full tscircuit runtime environment, including Sucrase transpilation and execution, so you just need to send the code to be executed with automatic handling of imports from `@tsci/*`

Circuit SDK on-chain reads — StakePoint stake verification + CIRC balances via pure JSON-RPC (no @solana/web3.js).

Circuit SDK agent bundles — build, sign, verify, and unpack content-addressed (sha256) signed agent bundles. The canonical codec shared by the Circuit agent cloud and the circuit CLI.

Local circuit-breaker analyzers for AgentInspect trace patterns

A package containing circuit dependent types which are relevant through all the Aztec Typescript codebase.

The `circuits` package exports the circom circuits needed for building on ZK Email.

Circuit SDK — batteries-included meta-package re-exporting @circuit-llm/{core,x402,inference,models,data,wallet}.

Hystrix-like circuit breaker for JavaScript.
