How this service works
GPT-5.6 Luna API Base USDC and OpenAI-compatible x402 chat: one request for $0.00293, paid by browser wallet or a quote-first agent fallback.
Output
Returns a JSON object confirming the purchase with: pack ID ('gpt-5.5-100-call-pack'), model name ('gpt-5.5'), price, title ('GPT-5.5 100 Prepaid Call Credits'), a prepaid token (pk_test_***), discount factor (0.8), exact USD price (~$1.59992), call count (100), remaining calls (100), and product ID ('model-call-pack').
Example use cases
Bulk credits for agent pipeline
“I'm building an agent that needs to call GPT-5.5 a lot — grab the 100-call prepaid pack for $1.60 USDC so I don't have to pay per request each time.”
Discounted API access for a prototype
“I want to prototype an app using the GPT-5.5 API cheaply. Buy me the 100-call pack with the 0.8 discount applied and return the prepaid token I can use.”
Restocking call credits mid-workflow
“My GPT-5.5 call credits are running low — purchase another 100-call pack for $1.60 USDC via x402 and show me how many calls I have remaining after.”
Technical details
Endpoint
GEThttps://gpt55.558686.xyz/v1/paid/call-packs/gpt-5.5-100?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to bulk-purchase 100 prepaid GPT-5.5 API call credits at a discounted rate ($1.60 USDC for 100 calls, ~$0.016/call) via x402 USDC payment on Base, rather than paying per individual call. Prefer this over per-call endpoints when running pipelines, agent workflows, or prototypes that will make many sequential requests and want lower per-call cost and a reusable token.
Side effects
- Payment not authorized or insufficient USDC balance — x402 payment fails and no pack is issued
- Invalid or malformed request path — returns error if pack ID not found
- Rate limiting or quota exceeded on the gateway — request rejected
- Network or upstream gateway timeout — no pack created
- x402 facilitator unreachable — payment flow cannot complete
