Low-Price GPT-5.5 x402 API
gpt55.558686.xyz
· GPT-5.5 x402 API Gateway
Price-first GPT-5.5 compact chat at $0.0001, long chat at $0.002134, max-output chat at $0.066667, and text microtasks at $0.0001 over x402 USDC on Base. Market benchmark: public x402 API listings commonly use per-call pricing around $0.001-$0.01; this gateway advertises a $0.0001 compact GPT-5.5 entry request, $0.002134 long-output GPT-5.5 requests, and $0.066667 true max-output GPT-5.5 requests. At the public max limits, $0.0001 is about 2.6% of the official token-cost estimate, roughly 38.2x cheaper. Best for agents that need cheap one-call GPT-5.5 access without API-key onboarding or subscription setup. Long tier supports up to 4096 output tokens with proportional pricing. Max tier supports up to 128000 output tokens with proportional pricing.
