How this service works
Payment-gated AI and browser automation API using the x402 protocol. All /v1/* endpoints require USDC payment on Base (eip155:8453) via x402 v2 exact scheme.
Output
The agent receives a reasoned AI-generated response to the submitted input, produced by the AI reasoning engine behind the x402-gated endpoint. The response reflects analysis, inference, or text generation based on the provided prompt body.
Example use cases
On-demand logical inference task
“Can you reason through this multi-step logic puzzle for me: if Alice is taller than Bob, and Bob is taller than Carol, who is the shortest? Send it to the Tanship AI reasoning endpoint and pay per call.”
Autonomous agent decision-making
“My agent needs to decide whether to approve or reject this loan application summary — can you run it through the Tanship PayAI reasoning endpoint and get a recommendation with justification?”
Pay-per-use AI analysis without subscription
“I don't want to pay a monthly AI subscription — just run this contract clause through the Tanship reasoning API once and tell me if there are any red flags, paying the small USDC fee per call.”
Technical details
Endpoint
POSThttps://x402.tanship.dev/v1/ai/reasonWhen to prefer
Choose this endpoint when you need AI reasoning on a pay-per-call basis without committing to a subscription, especially in autonomous agent workflows where cost control per inference matters. It is particularly well-suited for blockchain-native or Web3 agent stacks that already handle x402 USDC micropayments on Base. Prefer it over traditional API-key LLM providers when you want on-chain payment settlement and per-call billing transparency.
Side effects
- 402 Payment Required — x402 payment header missing or USDC payment on Base not confirmed
- Invalid input schema — missing required fields (type, method, bodyType, body)
- Payment amount mismatch — sent amount does not match the required $0.008 USDC
- Network error on Base chain — payment transaction not confirmed in time
- Unsupported bodyType — value outside json/form-data/text enum
- Empty or malformed body — reasoning engine receives no actionable input
