How this service works
Create a bounded spend plan without spending money.
Output
A structured spend plan showing which candidate x402 resources are selected, how the budget is allocated across them, their ranked priority, and the projected total cost — all without triggering any actual payment transactions.
Example use cases
Agent budget allocation for data APIs
“I have $10 to spend on x402 data APIs for my research agent. The goal is to gather financial news and sentiment data. Can you build a procurement plan across these five candidate endpoints without actually spending anything yet?”
Pre-approval spend simulation for multi-step workflow
“Before my agent starts executing, I want a bounded spend plan covering up to $3 for these four x402 endpoints — the goal is image captioning and object detection. Show me how the budget would be allocated across them.”
Vendor selection for a frugal autonomous buyer
“My agent needs to pick the best combination of x402 APIs for answering legal document questions, but I can only spend $2 total. Create a plan that ranks and selects from these six candidate resources so I know which ones to approve before any payment goes out.”
Technical details
Endpoint
POSThttps://trust402.vercel.app/api/procurement/planWhen to prefer
Use this endpoint when you need to decide which x402 APIs to purchase before committing funds — it is the right choice for pre-flight budget planning, agent spend governance, or generating an approval payload for human review. Prefer it over the quote endpoint when you want a full multi-resource plan rather than a single-resource quote, and over the ranking endpoint when you need budget-bounded allocation rather than just a ranked list.
Side effects
- Budget too low to cover any candidate's minimum price — returns empty or infeasible plan
- Invalid or missing goal string — plan may be unscored or poorly ranked
- Candidates missing required endpoint/url field — schema validation error
- Candidate price fields absent or unparseable — endpoint excluded from plan
- Budget exceeds reasonable sanity limits — may return error or capped plan
