PayPerQ (PPQ.AI)

PayPerQ is a pay-per-use AI access platform that solves a straightforward problem: most people who use AI tools irregularly or professionally across multiple providers are still paying flat subscription fees they cannot justify. PPQ.AI lets users pay only for the queries they actually make—averaging around $4 per month in practice—while accessing the full breadth of frontier models from a single interface.

Core Mechanism

The platform aggregates models from OpenAI (including GPT-5), Anthropic (Claude), Google (Gemini), Meta, Mistral, DeepSeek, Perplexity, xAI (Grok), and others under a single API and web interface. Users top up a balance—minimum $0.10—and pay per token or per generation event, with no recurring billing. There is no mandatory account creation; the platform explicitly supports anonymous crypto payments without email registration.

Queries are routed through PayPerQ's infrastructure to whichever upstream provider hosts the selected model. Model selection is exposed directly: users pick by name (e.g., claude-sonnet-4.6, openai/gpt-5.5) and can append routing suffixes to influence how the platform fulfills the request:

• :nitro — prioritize throughput speed
• :floor — prioritize lowest price
• :online — attach real-time web search
• :thinking — enable extended reasoning variant

An AutoClaw smart-routing layer, introduced in February 2026, can also automatically select the best model for a given query without user configuration.

API and Developer Integration

The API surface is intentionally OpenAI-compatible. Developers change only the base URL to https://api.ppq.ai and their existing OpenAI SDK code works without modification. This compatibility extends to a Responses API endpoint designed as a drop-in replacement for OpenAI's agentic-loop interface.

Documented integrations cover Claude Code, Claude Desktop, Cursor, Cline, Aider, OpenWebUI, Roo, Kilo Code, and other popular developer tools—each requiring only a base URL change and a PPQ API key. Payment can also be handled entirely programmatically via the L402 protocol: developers pay for individual requests over Bitcoin Lightning without an account or stored balance.

Beyond chat completions, the API supports speech-to-text (Deepgram Nova-3), text-to-speech (Deepgram Aura, ElevenLabs), image generation, asynchronous video generation, audio transcription, embeddings, and a set of 39 data enrichment endpoints covering people search, company lookup, and web scraping.

Privacy Architecture

PayPerQ offers three privacy tiers that users select based on their threat model:

Anonymous — No account, no email, payments via crypto. Queries may be logged by upstream providers under their standard policies.

Zero Data Retention (ZDR) — Opt-in routing parameter (provider: { "zdr": true }) that restricts upstream providers from storing prompt data. Requires account-level configuration.

Trusted Execution Environment (TEE) — End-to-end encrypted inference powered by Tinfoil running on NVIDIA GPU secure enclaves. The encryption flow encrypts the prompt in-browser before transmission; the ciphertext passes through PayPerQ's servers unreadably, decrypts only inside the hardware enclave, and the response returns encrypted. Cryptographic attestation—a verifiable proof of which code runs in the enclave—is surfaced to users via a shield icon in the interface. Even PayPerQ itself cannot read TEE-routed queries. Eight models ranging from 31B to 284B parameters, with context windows up to 1 million tokens, are available via TEE as of mid-2026. Developers can access TEE models via the open-source ppq-private-mode proxy with OpenAI- and Anthropic-compatible endpoints.

Products

Web App — Browser-based chat interface with local conversation storage, multi-model switching, and optional persistent memory across sessions. A Multi-Model Chat feature introduced in August 2026 allows sending a single prompt to multiple models simultaneously and comparing responses side by side.

Private Whisper — A desktop application providing AI-powered voice dictation that works inside any application where typing occurs. Introduced in February 2026, it connects to the PPQ API for transcription.

API — The OpenAI-compatible API serves as the backbone for third-party tool integrations. Per-key spending limits (daily, weekly, or monthly) and a query history endpoint give developers programmatic cost controls.

Payments and Crypto Integration

PayPerQ accepts approximately 13 cryptocurrencies at checkout, explicitly including SOL (Solana) and USDC/USDT on Solana, alongside Bitcoin, Bitcoin Lightning, Ethereum, Monero, Litecoin, DOGE, BNB, Dash, and TRX. Credit card payments are also available. Gift cards sold through Bitrefill make top-ups accessible to users without direct crypto wallets. The platform maintains an active Lightning Network node and supports Nostr Wallet Connect (NWC) for automatic Lightning-based top-ups.

There is no native PPQ governance or utility token. The crypto integration is payment-layer only: SOL and other assets serve as top-up methods, not staking or governance instruments.

Team and Background

Matt Ahlborg founded PayPerQ with an explicit goal of making it the preferred AI interface for crypto-adjacent developers and professionals worldwide. Rafael Valverde serves as CTO. The project launched in February 2024. Consistent product releases through 2025 and 2026—including TEE inference, multi-model chat, memory, data enrichment endpoints, and routing preferences—reflect sustained active development.

Solana Ecosystem Fit

PayPerQ occupies an adjacent position to the Solana ecosystem: it is not a DeFi protocol, does not deploy programs on-chain, and carries no Solana-native tokenomics. Its relevance to Solana users comes from two angles. First, it accepts SOL and Solana-based stablecoins as payment methods, making it a practical AI utility for holders who prefer spending SOL rather than converting to fiat. Second, its privacy and permissionless access model—no email, anonymous crypto payments, L402 pay-per-request—resonates with the same values that draw developers to crypto-native infrastructure. The blog's Nostr integration guides and Bitcoin Lightning payment rails position PPQ.AI as infrastructure that crypto developers reach for when they need AI without surveillance or subscriptions.
