Build on Trading & Intelligence APIs
Signals, market data, and pay-per-query intelligence — one REST API with replay-safe webhooks, and forward-deployed engineers to help you ship.
// Run a Deep Intelligence query — paid via x402
const report = await fexr.markets.query({
tier: 'deep_intelligence', // $2.00 USDC
topic: 'l2-token-unlocks',
format: 'json'
});
// Subscribe to signal events
fexr.webhooks.on('signal.published', handleSignal);消费者+链上，统一
构建将现实世界的商务与区块链合约连接起来的应用程序。 Fexr 简化了集成，以便您可以专注于您的产品。
Trading Signals Feed
Pull AI signals with plain-English risk summaries over REST, or receive them as webhook events the moment they publish. Filter by market and signal type.
Market Intelligence Queries
Call pay-per-query reports programmatically — your code pays in USDC over x402 per request, from $0.50 a query. No API contract, no key provisioning wait.
Account & Order Events
Replay-safe webhooks push order previews, executions, and portfolio changes to your stack in real time — every event signed and audit-logged.
Portfolio Data
Read positions, PnL, and margin health for connected accounts — the same data behind the app's portfolio view, available to your own tools.
内置合规性
Fexr is non-custodial by design: user funds stay in user wallets under capped, revocable permissions, and every API action is audit-logged. Read Fexr's infrastructure classification under FATF Recommendation 15 →
Sandbox First
A sandbox environment mirrors production behavior, so you can test signals, webhooks, and query flows without live transactions.
Agent automation
Wire AI agents that read signals, run market-intelligence queries, and pay per query over x402 — all within caps and permissions the user defines.

开发者常见问题解答
基于 Fexr 的团队提出的常见问题。
01.What does the FDE engagement look like?
我们的前沿部署工程师加入您的 Slack，审查您的架构，构建自定义连接器，并在发布过程中随时待命。将他们视为您团队的延伸。
02.Can I deploy my own contracts?
Yes. Bring your own stack and connect it to Fexr over REST and webhooks — you own the application and control the business logic; Fexr provides the signals, data, and execution rails.
03.How do you handle compliance?
Fexr is non-custodial: user funds stay in user wallets under capped, revocable permissions. Our team reviews your use case and helps ensure your integration design meets the requirements of your jurisdiction.
04.Which chains are supported?
Trading executes on Hyperliquid, funded with USDC via Arbitrum. Market-intelligence queries settle in USDC over x402 on Base.
