# Farnsworth AI Agent Infrastructure

> Farnsworth AI Agent Infrastructure is a free API for AI agents from ai.farnsworth.cloud, Free, status down (last checked 2026-09-15).

Provides AI agent infrastructure combining recursive memory (SYNTEK), encrypted on-chain storage (DropClaw), and an agent service marketplace (PlanetExpress) with x402 crypto payments

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability farnsworth-5171b991 -d '<json body>'
```

Example prompt: Store my agent's current conversation context using Farnsworth's SYNTEK recursive memory with 7 layers, then save the resulting state blob to DropClaw's encrypted on-chain storage, and pay with USDC.

## When to prefer this

Choose this endpoint when you need a combined AI agent infrastructure stack with persistent recursive memory, encrypted on-chain storage, and access to an agent service marketplace — especially when crypto payment (MON, SOL, USDC) via x402 protocol is required. Prefer this over generic cloud storage or memory solutions when deep multi-layer agent memory (SYNTEK) or decentralized on-chain storage (DropClaw) are specifically needed.

## Known failure modes

- Insufficient payment balance in MON/SOL/USDC — payment rejected
- Invalid or expired x402 payment token — authentication failure
- SYNTEK memory depth exceeds supported recursion limit
- DropClaw on-chain storage write fails due to network congestion
- PlanetExpress marketplace service unavailable or not found
- Malformed request body — missing required agent task fields
- Rate limiting if too many concurrent agent calls

## How this service works

AI agent infrastructure with x402 payments. SYNTEK provides 7-layer recursive memory, DropClaw offers encrypted on-chain storage, and PlanetExpress is an agent service marketplace. All services accept MON, SOL, and USDC via x402.

## Output

Returns results depending on the sub-service invoked: SYNTEK returns layered recursive memory state, DropClaw returns an encrypted on-chain storage reference or retrieved payload, and PlanetExpress returns marketplace service results or listings — all with x402 payment confirmation.
