A high-performance index and search API designed for the AI agent economy. Free tier is open. Premium endpoints are x402-gated, settled in stealth USDC via the Pakana protocol. No API keys, no rate limit tables, no identity exposed by either side.
AI agents are the fastest-growing category of API consumers. They cannot click through OAuth flows, cannot manage credentials in a password manager, cannot read pricing pages. They can pay. The web has no native way for an autonomous program to pay for an HTTP request — until x402.
TurboDex is built x402-native from the first endpoint. An agent that needs a semantic search result sends an HTTP GET; the server responds with HTTP 402 Payment Required and a quote denominated in USDC; the agent's Pakana wallet generates a stealth payment and a Groth16 proof; the proof is verified on Stellar Mainnet; the search response is returned. End to end, sub-second. No account creation. No API key rotation. No agent doxxing itself to the search service.
Standard keyword and metadata search across the indexed public web. Rate-limited per IP, no payment required, no privacy guarantees beyond standard HTTPS. Useful for prototyping, not production agent workloads.
Vector-based semantic search across the same corpus. Per-query pricing in USDC, paid via stealth payment. The search service does not link queries to a paying identity — only to a one-shot stealth address.
On-demand crawl and parse of a target URL with structured extraction. Per-URL pricing. Useful for agents that need fresh data outside the index window.
Full-text and structured search over Stellar Mainnet transactions, contracts, and Soroban events. Per-query pricing. Built for agents and analysts working with on-chain data.
x402 over HTTPS, settled in Stellar USDC, verified by the Pakana protocol.
The TurboDex server forwards the proof to the Pakana x402 facilitator, which verifies it on-chain via PakanaTracker. If the proof is valid and the payment matches the quoted price, the response is returned. Latency is dominated by Stellar's 5-second finality, with proof verification adding less than 100ms.
TurboDex public endpoints are free. Premium endpoints — semantic search, full-text indexing, real-time crawl — are x402-gated. Get an early-access wallet and start querying.
