How this service works
Create a bounded spend plan without spending money.
Output
A JSON object with an 'ok' boolean, the tool name ('procurement.plan'), and a 'recommendation' field (e.g. 'approve-after-review') indicating whether the buyer should proceed with the candidate set, along with any ranked or scored breakdown of the candidates.
Example use cases
Rank data-enrichment APIs by value
“I'm looking at four x402 endpoints for real-time customer profile enrichment and I've got $3.50 to spend. They're at https://api.dataprovider.io/enrich, https://api.intel.com/profile, https://api.signals.eth/match, and https://api.verify.xyz/validate — priced at $0.05, $0.08, $0.04, and $0.06 per call. Can you score them against my enrichment goal and recommend which ones I should actually approve?”
Find trustworthy APIs within strict budget
“I need to integrate three pay-per-call endpoints into my automation workflow but I only have $1.00 to spend this month. The candidates are https://api.classify.io/categorize at $0.015, https://api.extract.com/parse at $0.025, and https://api.transform.ai/convert at $0.020. Which of these should I trust and approve given my budget and classification task?”
Plan multi-API spending across suppliers
“We're building a document processing pipeline and considering five different x402 suppliers for OCR, entity extraction, and validation. My procurement budget is $5.00 and I need recommendations on which combo of these endpoints represents the best trust-to-cost ratio. Can you evaluate them and give me a ranked approval plan?”
Technical details
Endpoint
POSThttps://trust402.aztecbeacon.uk/api/procurement/planWhen to prefer
Use this endpoint when an AI agent needs to autonomously decide which x402 pay-per-call APIs to purchase or invoke, especially when comparing multiple candidates against a fixed budget and a specific task goal. It is the right choice when you need a structured trust assessment and procurement recommendation before committing micropayments, rather than paying blindly or manually comparing endpoints.
Side effects
- Missing or empty 'goal' field causes unscored or rejected plan
- Budget of 0 or below may result in all candidates being rejected
- Candidates with no 'endpoint' or 'url' field fail schema validation
- Malformed payTo address (not a valid 0x Ethereum address) causes candidate rejection
- Unknown or unsupported network string may reduce scoring confidence
- Empty candidates array returns a trivially empty plan
- Price fields with non-numeric strings may be ignored or cause parse errors
