How this service works
Rank 2-10 candidate paid resources for a goal, budget, and risk policy.
Output
A ranked list of candidate x402 resources ordered by alignment to the stated goal, price fit within the budget, and risk policy compliance — including scores, recommended pick, and any candidates flagged for disqualification.
Example use cases
Budget-constrained agent resource selection
“I've got 4 candidate x402 endpoints that could all answer my data enrichment goal, but my total budget is $0.20. Rank them by fit and price so my agent calls the best one first.”
Risk-filtered API comparison for autonomous workflow
“Before my agent spends anything, compare these 3 paid APIs against my low-risk policy — I only want to pay for endpoints that are verified and have proof-ready receipts. Which one should it use?”
Multi-vendor scoring for a specific AI task
“I'm building an agent that needs to geocode addresses and I have 6 x402 candidate services at different price points. Rank them by how well they match that goal and which offers the best value under $0.10 per call.”
Technical details
Endpoint
POSThttps://trust402.vercel.app/api/trust/compare-resourcesWhen to prefer
Use this endpoint when an agent has already discovered multiple x402 candidate APIs and needs to make a cost- and trust-aware selection decision before spending money. Prefer it over manual comparison or random selection when budget constraints, risk policies, or goal alignment matter. Especially valuable in autonomous purchasing workflows where the agent must justify its API choice.
Side effects
- Fewer than 2 candidates provided — endpoint requires a minimum of 2 for comparison
- Candidates missing required endpoint or url fields — schema validation error
- budgetUsd is zero or negative — no candidates can qualify
- All candidates exceed the budget — returns empty or all-disqualified ranking
- Malformed x402 metadata on candidates — scoring degrades gracefully but may reduce accuracy
- Payment of $0.03 USDC not completed — returns 402 challenge before processing
