What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of x402.aibtc.dev controls every word below.

LLM Inference (OpenRouter)

Access 100+ LLM models via OpenRouter with dynamic pricing. POST /inference/openrouter/chat with model and messages. Pricing is dynamic: model cost + 20% margin. First request returns 402 with payment amount. Retry with payment-signature header for completion.

inferencellmopenrouterchatgptclaudellama
Examples it gives
  • Generate text with GPT-4o
  • Chat with Claude via x402 payment
  • Use Llama 3 with STX payment

LLM Inference (Cloudflare AI)

Cloudflare-hosted AI models at standard fixed pricing (0.001 STX). POST /inference/cloudflare/chat with @cf/ model id and messages.
