# MapleAI Autonomous Agent Execution

> MapleAI Autonomous Agent Execution is a paid API for AI agents from base.mapleai.shop, paid per call via x402, $0.0145/call, status unknown (last checked 2026-10-02).

Executes a multi-step autonomous agent that reasons and uses tools (calculator, URL fetch) to complete a natural language task, billed per call plus per reasoning step

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 mapleai-autonomous-agent-execution-41bb0883 -d '<json body>'
```

Example prompt: Use the agents/oss-20b model to autonomously figure out the current USD to EUR exchange rate and calculate how much €500 converts to in USD — let it fetch URLs and use the calculator, with up to 10 reasoning steps.

## When to prefer this

Choose this endpoint when a task requires multiple sequential reasoning steps, tool calls (web fetching or calculation), and autonomous decision-making rather than a single-shot LLM completion. It is ideal when you cannot predict ahead of time exactly how many steps or which tools will be needed. Prefer a simple chat completion endpoint for tasks that require only one model call with no tool use.

## Known failure modes

- max_steps exceeded — agent hits the step ceiling without completing the task
- tool failure — fetch_url returns an unreachable URL or the calculator receives malformed input
- model unavailable — agents/oss-20b engine is temporarily offline or overloaded
- task too ambiguous — agent cannot determine a concrete action plan from the natural language task
- payment failure — x402 USDC payment is rejected or insufficient
- timeout — long-running tasks exceed server time limits

## How this service works

4 GPT models, 7 image models, and Jev structured decisions. Pay per request in USDC on Base with x402.

## Output

Returns the final answer or output produced by the agent after completing its reasoning and tool-use steps, along with metadata about how many steps were taken and what tools were invoked during execution.
