How this service works
HTTP-402 gated ChatGPT and Claude Opus inference. $0.02–$0.05 USDC per call, settled in <2s on Base via the x402 protocol. No API keys, no signup, no subscriptions.
Output
A JSON chat completion object mirroring the OpenAI ChatCompletion schema, including the assistant's message content, finish reason, model name ('auto'), and an extra `x_clawy` field indicating which provider (e.g. 'anthropic') and delivery method (e.g. 'claude-cli') was used. Payment is settled on Base in under 2 seconds via the x402 protocol before the response is returned.
Example use cases
One-off AI answer without subscription
“I need a quick AI-generated explanation of how transformer attention mechanisms work — just pay the tiny USDC fee per call, I don't want to sign up for anything.”
Autonomous agent using frontier models
“My agent needs to call Claude Opus to evaluate this legal clause and flag any ambiguities — route it through Clawy so it pays per call in USDC on Base with no API key needed.”
Cost-controlled LLM experimentation
“Run this prompt through whichever frontier model Clawy picks automatically and bill me the micro-USDC amount: 'Draft three tagline options for a sustainable sneaker brand targeting Gen Z.'”
Technical details
Endpoint
POSThttps://clawy.uk/v1/chat/autoWhen to prefer
Choose Clawy when you need one-off or low-volume LLM inference without committing to a subscription or storing API keys — particularly in autonomous agent pipelines that already handle x402 USDC micropayments on Base. It is ideal when you want cost-per-call billing at $0.02–$0.05 USDC and access to both OpenAI and Anthropic models behind a single endpoint with automatic routing.
Side effects
- HTTP 402 returned if the x402 payment header is missing or the USDC balance is insufficient
- Payment settlement timeout on Base can cause delayed or failed responses
- Model routing ('auto') may select a provider that is temporarily unavailable, causing a 503
- Malformed messages array will result in a 400 bad request
- Rate limiting may apply if too many concurrent calls are made from the same wallet
