How this service works
Produce a concrete quote and approval payload for a multi-resource purchase path without spending.
Output
Returns a structured quote object with a ranked list of selected x402 resources that fit within the budget, per-resource price breakdown, total estimated cost, and a ready-to-sign approval payload that can be passed to a payment executor — all without triggering any actual transactions.
Example use cases
Budget-capped agent procurement plan
“I have a goal of 'summarize recent news for 10 topics' and a $1.50 budget. Here are 5 candidate x402 API endpoints with their prices and descriptions — can you produce a quote and approval payload that fits within budget without making any payments?”
Pre-flight cost check for agentic workflow
“Before my agent starts running, I need a concrete quote for these 4 x402 resources it wants to call — the goal is 'generate weekly market reports', budget is $3.00. Show me what the spend plan would look like and give me an approval payload I can review first.”
Multi-vendor x402 resource selection quote
“I'm comparing 6 paid API endpoints for my goal of 'translate and classify customer feedback'. My max budget is $0.50 per run. Can you rank these candidates and give me a quote with an approval payload so I can authorize the best combination?”
Technical details
Endpoint
POSThttps://trust402.vercel.app/api/procurement/quoteWhen to prefer
Use this endpoint when an agent needs to plan and review a multi-resource x402 purchase before committing funds — especially when working with a fixed budget across heterogeneous candidate endpoints. Prefer this over the single-endpoint probe when you have 2–10 candidate resources and need a ranked, cost-bounded selection with an approval artifact. Choose this over the spend-plan endpoint when you need a concrete, signable quote payload rather than just a budget allocation sketch.
Side effects
- Budget too low to cover any candidate resource — returns empty plan or error
- Invalid candidate endpoint URLs — schema validation failure
- Missing required 'goal' or 'budgetUsd' fields — 400 bad request
- All candidates lack x402 metadata — scoring impossible, returns degraded quote
- Payment asset or network mismatch across candidates — may exclude incompatible resources
- Endpoint returns 402 during enrichment probe — expected, handled gracefully
