How this service works
Guardian Gate — before your agent pays ANY other x402 service, grade the payTo counterparty + spend shape in one cheap call. Patterns, not verdicts. Agent guide: use before non-Guardian awal x402 pay. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a pattern-based risk signal object describing the payTo counterparty's behavioral profile and spend shape characteristics — not a binary verdict but observable patterns (e.g. dormancy, burst activity, anomaly flags) that the agent can use to decide whether to proceed with payment.
Example use cases
Pre-payment counterparty risk screen
“My agent is about to pay 0xabc123... on Base chain for an x402 API call — can you run Guardian Gate on that address and tell me the risk patterns before we send anything?”
New x402 skill vetting
“I found a new x402 service I want my agent to use, the payTo is 0xdef456... — check it with Guardian Gate before we commit any spend, the resource URL is https://someservice.dev/api/endpoint.”
Solana x402 counterparty check
“Before my agent pays that Solana-based x402 endpoint, can you screen the payTo address CK7b...XYZ on Solana through Guardian Gate so I can see any risk signals on their spend shape?”
Technical details
Endpoint
GEThttps://cyre.dev/api/gateWhen to prefer
Use this endpoint as a lightweight pre-flight check before any non-Guardian x402 payment — it is the cheapest entry point in the CYRE Guardian suite ($0.001 per call). Prefer Guardian Gate when you only need basic counterparty + spend-shape patterns for a single payTo address. Use Guardian Bazaar Scan if you also want to probe the resource URL itself, or Guardian Settlement Batch when grading multiple payout addresses simultaneously.
Side effects
- Missing required payTo parameter returns validation error
- Invalid address format (malformed 0x or non-base58) may return error or low-confidence result
- Unsupported chain identifier returns error
- Network timeout on counterparty data lookup
- Unknown or brand-new address with no on-chain history may return minimal/empty pattern data
