name: x711.io
description: x711.io is a tool-execution host on Base that exposes a suite of utilities (web search, price feeds, transaction simulation, onchain insight) through a single endpoint. Payment is handled via x402 USDC micropayments, API key authentication, or a free tier. Each call is a single-shot invocation returning a discrete result.
host: x711.io

# x711.io

x711.io serves agents that need on-demand access to a curated set of utility tools on the Base network without managing separate API integrations. It consolidates web search, token price data, transaction simulation, and onchain analytics behind one authenticated endpoint, with flexible payment options including x402 micropayments.

## When to use this host

Use x711.io when an agent needs a lightweight, pay-per-call gateway to web search, price feeds, transaction simulation, or onchain analytics on Base, especially when x402 micropayment handling is required. Do not use it for cross-chain operations on networks other than Base, for streaming or subscription-style data feeds, or for bulk/batch data retrieval. If an agent needs dedicated, high-throughput price feeds or persistent data streams, a specialized oracle or indexer host would be more appropriate.

## Capabilities

### Multi-Tool Execution

Invokes any tool in the x711.io suite (web_search, price_feed, tx_simulate, onchain_insight) on Base with payment and authentication handled automatically per call.

- **`refuel-agent-tool`** — Executes a selected tool from the x711.io suite on Base, with payment handled via x402 USDC, API key, or free tier.

## Skill reference

### `refuel-agent-tool`

**Refuel API** — Executes a selected tool from the x711.io suite on Base, with payment handled via x402 USDC, API key, or free tier.

*Use when:* Use when an agent needs to invoke a specific x711.io tool (e.g., web_search, price_feed, tx_simulate, onchain_insight) and must handle x402 micropayment or API key authentication on Base.

*Not for:* Do not use for cross-chain operations outside Base or for streaming data feeds; this is a single-shot tool execution endpoint.

**Inputs:**

- `tool` (string, required) — The tool to execute. Must be one of the supported enum values such as web_search, deep_search, price_feed, hive_read, hive_write, tx_simulate, tx_broadcast, onchain_insight, wallet_investigate, agent_see, agent_act, llm_routing, code_sandbox, email_send, and others.

**Returns:** Returns a 200 with a Hive-enriched tool result object; returns 402 if payment via x402 USDC on Base or API key credits is required.

**Example:** `{"tool": "price_feed"}`
