How Payment Works

BotIndex uses x402 — the HTTP 402 Payment Required protocol by Coinbase.

Your Agent → calls botindex tool
MCP Server → GET king-backend.fly.dev/api/botindex/v1/sports/odds
           ← 402 + payment instructions (amount, wallet, network)
           → pays USDC on Base via x402
           ← 200 + data

No API keys. No signup. No rate limit tiers. Your wallet is your identity.

Free Trial

Every wallet gets 50 free premium requests. Just send an X-Wallet: 0x... header. The response includes X-BotIndex-Free-Remaining so you know exactly where you stand. After 50 requests, x402 payment kicks in automatically.

To enable automatic payments after trial, configure your agent with a funded Base wallet and the @x402/client SDK.

Free Endpoints (No Payment)

These work out of the box — no wallet needed:

• botindex_discover — full endpoint catalog with pricing

• Zora trending coins (via API: /api/botindex/zora/trending-coins)

• Hyperliquid funding arb (via API: /api/botindex/hyperliquid/funding-arb)

Free vs Pro

• Free key: 100 requests/day on free endpoints. Premium endpoints return an upgrade/payment prompt.

• Pro key ($29/mo): Unlimited access to all endpoints with no x402 payment gates.

Verifiable Agent Actions (AAR)

Every BotIndex API response carries a signed Agent Action Receipt in the X-AAR-Receipt header — Ed25519-signed proof of what your agent requested, what was returned, and what it cost.

• Verify any receipt independently — no trusted intermediary needed

• Privacy-preserving — inputs/outputs are SHA-256 hashed, not exposed

• Compatible with — bidirectional mapping

• Aztec ZK-compatible — verify on-chain without revealing contents

npm install botindex-aar

import { verifyReceipt } from 'botindex-aar';
const result = verifyReceipt(receipt);
// { ok: true } — receipt is valid and untampered
