Delx Commerce Token Budget Split
x402
Delx Commerce Token Budget Split is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).
Computes how to split a model's context window into system, input, and output token budgets given total and reserved token counts

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the requested token split is feasible, along with the calculated available_input_tokens, and echoes back total_tokens, system_tokens, and reserved_output_tokens for confirmation. Schema version is included as 'delx/util-token-budget-split/v1'.
Example use cases
LLM pipeline token planning
“My model has a 16,000-token context window, I'm using 1,200 tokens for the system prompt and need 2,000 reserved for the response — how many tokens do I have left for the user's input?”
Feasibility check before inference
“Before I run this agent, I want to make sure my token reservations are actually feasible: total window is 4096 tokens, system takes 800, and I need 512 for output. Is that going to work and what's left for input?”
Dynamic budget allocation in agentic loop
“In my agentic loop the context window is 32,768 tokens, system instructions are 3,000 tokens, and I always reserve 4,096 tokens for the model's reply — tell me the exact input budget I can pass to the user turn.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/token-budget-split?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or pipeline needs a lightweight, deterministic utility to compute safe token budgets before calling an LLM — especially useful in agentic loops where context management is dynamic. Prefer it over manual arithmetic when you need a verifiable, pay-per-use microservice with no signup overhead, paid via USDC on Base or Solana.
Side effects
- Infeasible split (available_input_tokens would be zero or negative): feasible returns false
- Missing required fields (total_tokens, system_tokens, reserved_output_tokens): likely 400 or validation error
- Payment failure via x402 protocol: 402 Payment Required if USDC payment not attached
- Non-numeric token values: schema validation error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| total_tokens | number | Model context window size in tokens. |
| system_tokens | number | Tokens already reserved for system/instructions. |
| reserved_output_tokens | number | Tokens reserved for model output. |
