## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402factory-ai-solanallmgpt6dsmq4ra7v3tctuws2-da92864e -d '<json body>'
```

Example prompt: Send a message to the Solana x402 GPT endpoint using gpt-5-mini with a max of 2000 output tokens and ask it: 'Summarize the key benefits of Solana for developers in 3 bullet points.'

## When to prefer this

Choose this endpoint when you need to call GPT with Solana-based x402 USDC micropayments, especially when building on-chain or Solana-native applications that require AI text generation with transparent per-token pricing. Also ideal for creating reusable custom agents with preprompts stored against a wallet identity.

## Known failure modes

- Input message exceeds max_input_tokens cap — server returns error instead of processing
- Insufficient USDC balance for x402 payment — payment fails before LLM is called
- Invalid or expired custom_id — agent not found
- Model name not supported — returns model error
- Rate limit or OpenAI API error downstream — 502 or error response
- Malformed request body — 400 bad request

## How this service works

Solana GPT wrapper API using x402 payments. Default direct call: model gpt-5-mini, max_output_tokens=2000, fixed price 0.01 USDC for up to 1000 input tokens. For all other settings the price is computed per model as (input_tokens * input_price_per_million + max_output_tokens * output_price_per_million) / 1,000,000, with a minimum of 0.001 USDC and always rounded up to 6 decimals. Optional max_input_tokens lets you cap the input tokens used for pricing; if the message is longer than this cap the server returns an error instead of under-pricing. Optional action=create creates a custom agent with the given message as preprompt for 0.001 USDC (no OpenAI call), stores a base_price_usdc using (max_input_tokens_for_agent or 1000) + preprompt + max_output_tokens, and returns a custom_id. Optional action=list lists up to 100 recent custom agents for the paying wallet for 0.001 USDC without calling OpenAI. Custom agents can be called via POST /solana/llm/gpt with custom_id, or POST /solana/llm/gpt/{custom_id}. Each custom agent has a fixed price per call based on its stored preprompt, model, max_output_tokens and max_input_tokens; if the runtime message is longer than max_input_tokens the server returns an error. Custom LLM agent 6DSMQ4RA7V3TCTUWS2 on Solana. Model gpt-5-mini, max_input_tokens=5000, max_output_tokens=5000. Preprompt preview (first 150 chars): "can you read these 5 topics and create a script for a tts function, only reply with the text script what the voice need to say, nothing else". Pricing mode: agent-per-token. Prepaid price (x402) for this request: 0.017019 USDC. Estimated input tokens for pricing: 5047.

## Output

Returns the LLM-generated text response for the given message. If action=create, returns a custom_id for the newly created agent. If action=list, returns up to 100 recent custom agents associated with the paying wallet. Pricing metadata may also be included.
