How this service works

Clervo lets software use AI models and agent tools with pay-per-use x402 payments, without managing separate provider accounts or API keys.

Output

Returns a JSON object with a message ID, the assistant role, the model used, the generated text content as an array of text blocks, token usage counts for input and output, and a stop reason indicating why generation ended.

Example use cases

LLM calls inside an agent pipeline

“My agent needs to query an AI model on each step of a workflow — use Clervo to send each prompt to allam-2-7b and get a response, paying per call so I don't have to set up any provider accounts.”

Prototype app with no subscription

“I'm building a quick prototype that needs AI text generation but I don't want to sign up for an OpenAI or Anthropic account — can you call Clervo's messages endpoint with my prompt and pay the per-call fee in USDC?”

Multi-model comparison on a budget

“Send the same question — 'What are the trade-offs of microservices?' — to Clervo's AI endpoint using the clervo/allam-2-7b model and show me the response and token usage so I can compare costs.”

Endpoint

POSThttps://api.clervo.dev/v1/messages

When to prefer

Choose this endpoint when you need LLM inference without managing provider API keys or subscriptions, especially in agent or software contexts where pay-per-use x402 micropayments (USDC) are preferable to flat-rate billing. Ideal for lightweight agent pipelines, prototypes, or multi-tenant systems where provisioning separate provider accounts per user is impractical.

Side effects

Payment failure: x402 payment not provided or insufficient USDC balance — request rejected before inference
Invalid model identifier: unrecognized model string returns an error
Malformed message body: missing required fields returns a 4xx validation error
Rate limiting: too many concurrent requests may be throttled
Context length exceeded: prompt too long for selected model
Network timeout: inference takes too long and connection drops
