# x402 Agent Task Executor

> x402 Agent Task Executor is a paid API for AI agents from api.x-402.online, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-20).

Accepts an objective and budget, executes an autonomous agent task, and returns a verified result assembled via pay-per-call x402 micro-payments.

## 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 x402-agent-task-executor-2e798a1e
```

Example prompt: Run an agent task to find the current ETH price and summarize the top 3 recent news headlines about Ethereum — my budget is $0.10 USDC.

## When to prefer this

Choose this endpoint when you need an autonomous agent to complete a goal-oriented task within a defined USDC budget, especially when the task requires chaining multiple data lookups or API calls. Prefer it over single-purpose endpoints when the objective involves multiple steps, verification of results, or when you want budget-bounded execution without managing individual API calls yourself. Best suited for agents that need hands-off task delegation with a verified outcome.

## Known failure modes

- Insufficient budget to complete the task — agent halts and returns a budget-exceeded error
- Malformed or missing 'input' object — returns 400 validation error
- Task objective too vague or unsupported — agent may return empty or partial results
- x402 payment failure (insufficient USDC balance or allowance) — returns 402 Payment Required
- Network or downstream API failure during sub-task execution — partial result or timeout returned

## Output

A verified, assembled result corresponding to the submitted objective — the agent executes sub-tasks (potentially chaining multiple x402 pay-per-call APIs), aggregates outputs, and returns a structured or textual answer confirming task completion and findings.
