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.
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.
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 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.
Upgrade link: https://api.botindex.dev/api/botindex/keys/register?plan=pro
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 Mastercard Verifiable Intent — bidirectional mapping
- Aztec ZK-compatible — verify on-chain without revealing contents
