How this service works
Guardian Intent Exchange match — compare a sealed intent token to a vendor quote (URL, payTo, amount). Returns fit brief + next skills. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a fit brief describing how well the vendor quote matches the sealed intent token, along with recommended next skills to call. The response provides patterns and guidance rather than binary verdicts, helping the agent decide whether to proceed with payment.
Example use cases
Pre-payment intent-to-quote validation
“Before my agent pays that x402 skill at https://api.partner.dev/analyze, check if the quote with payTo 0xDEF456 for 0.01 USDC actually matches my intent token eyJpbnRlbnQiOiJidXkifQ== — I only want to proceed if it's a genuine fit.”
Budget guard for autonomous spend
“My agent is about to pay 0.003 USDC to payTo 0x789ABC at https://skills.example.com/summarize — compare that against my intent token eyJidWRnZXQiOjF9 and tell me if the quote is within the patterns I sealed in, plus what skill I should call next.”
Multi-vendor quote comparison workflow
“I have three vendor quotes coming in for my agent task — run my intent token eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCJ9 against the first one: URL https://vendor1.cyre.dev/extract, payTo 0x111222, amount 0.002 USDC, and tell me how well it fits before I evaluate the others.”
Technical details
Endpoint
GEThttps://cyre.dev/api/exchange/matchWhen to prefer
Use this endpoint when an autonomous agent has received a vendor quote for an x402-gated resource and needs to verify it aligns with a previously sealed intent token before committing payment. Prefer this over manual inspection when operating autonomously at scale or when budget/host constraints were encoded in the intent token. Best used as a pre-payment gate in agent payment pipelines on the cyre.dev Guardian system.
Side effects
- Missing intentToken query parameter returns validation error
- Malformed or expired intent token returns token parse failure
- Vendor URL unreachable may result in incomplete fit analysis
- Amount or payTo format mismatch returns schema validation error
- Rate limit exceeded returns 429 with retry guidance
