How this service works
Every model with holographic memory in front. No account, no API key, no subscription — pay per request in USDC, TOKEN, LEOS or USDG on Solana, Base, Robinhood Chain, eip155:137, eip155:42161, eip155:10 or eip155:480. The 402 quotes a discount off what the same request costs bought direct.
Output
Returns a JSON object containing a generation ID, usage statistics (token counts), and a choices array with the assistant's message role and content string — standard OpenAI-compatible chat completion format.
Example use cases
One-off AI drafting without account setup
“I need to draft a professional email declining a job offer but keeping the door open for future roles — use the OpenZoo pay-per-call chat API with USDC so I don't have to set up another subscription.”
Crypto-native agent pipeline text generation
“My Solana-based agent needs to generate product descriptions for three new items in our store — call the OpenZoo chat completions endpoint and pay per request in USDC on Base, no API key needed.”
Discounted LLM inference for cost-sensitive workloads
“Can you run this classification prompt through OpenZoo's holographic-memory-backed chat API? I want to take advantage of the discount versus buying direct from the model provider, and pay per call in USDG.”

Endpoint
POSThttps://api.openzoo.fun/v1/chat/completionsWhen to prefer
Choose this endpoint when you need LLM chat completions without account registration, API keys, or subscriptions — ideal for one-off requests, crypto-native agent pipelines, or when you want to pay per call in USDC or other supported tokens on Solana, Base, or EVM chains. It offers a discount vs. buying direct from the model provider and is compatible with the x402 payment protocol.
Side effects
- Payment not received or insufficient USDC/TOKEN/LEOS/USDG balance — returns HTTP 402 with a payment quote
- Unsupported blockchain or token — request rejected if chain not in supported list
- Malformed request body — 400 error if required fields missing or bodyType mismatch
- Model unavailable or overloaded — may return 503 or timeout
- Invalid or expired payment — transaction not confirmed on-chain before timeout
