## 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-solanallmgpt32x5w88z9patzh85t5-85a6ca6e -d '<json body>'
```

Example prompt: Ask the Solana x402 GPT endpoint to explain quantum entanglement in simple terms using model gpt-4o-mini with max 2000 output tokens, paying with my Solana wallet via x402.

## When to prefer this

Choose this endpoint when you need pay-per-call GPT access using Solana USDC micropayments via the x402 protocol, especially when you want transparent token-based pricing, the ability to create and reuse custom AI agents with preprompts, or when operating in a Solana-native payment environment without subscription overhead.

## Known failure modes

- Input message exceeds max_input_tokens cap — server returns error instead of under-pricing
- Insufficient USDC balance on Solana wallet for the computed price
- Invalid model name specified — unknown model error
- x402 payment header missing or malformed — 402 Payment Required response
- custom_id not found when invoking a custom agent
- Rate limiting or OpenAI upstream errors propagated back

## 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=message (or omitting action) performs a direct GPT call with the given message. 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 32X5W88Z9PATZH85T5 on Solana. Model gpt-5-mini, max_input_tokens=1000, max_output_tokens=2000. Preprompt preview (first 150 chars): ".". Pricing mode: agent-per-token. Prepaid price (x402) for this request: 0.006401 USDC. Estimated input tokens for pricing: 1001.

## Output

Returns the GPT model's text response to the input message, along with token usage metadata. For agent creation (action=create), returns a custom_id for future use. For action=list, returns up to 100 recent custom agents associated with the paying wallet. Pricing details and any errors (e.g. input too long) are also included.
