x402-agent-suite-production.up.railway.app
x402-agent-suite-production is a security and compliance middleware host designed for agents that make or receive x402 micropayments. It serves agent developers who need to gate payments behind risk checks, verify partner agent credentials via an attestation registry, and evaluate whether failed transactions qualify for refunds. Its distinct value is combining preflight spend/identity/URL safety checks with post-hoc refund arbitration and attestation verification in one host, purpose-built for the x402 protocol context.
Capabilities
Preflight Payment Safety
Runs spend-cap, identity-trust, and URL-safety checks before committing to an x402 payment, returning an allow/deny decision with a security grade and per-check breakdown.
check-pre-x402-guard
Attestation Registry and Verification
Looks up which agents hold valid attestations in the registry and verifies individual attestation IDs for validity, confidence score, and checks passed — enabling agents to gate partner interactions on credential status.

Refund Eligibility Arbitration
Evaluates whether a completed or failed x402 transaction qualifies for a refund based on seller verification signals such as endpoint reachability, response quality, and scoring, returning a graded eligibility decision with buyer guidance.

Workflows
Safe Paid API Call with Attestation Gate
Use when an agent needs to verify a target agent's attestation credentials and pass preflight safety checks before executing an x402 payment to that agent.
- 1fetch-attestation-registryQuery the attestation registry to confirm the target agent holds a valid attestation, optionally filtering by minimum grade.
- 2verify-attestation-signatureVerify the specific attestation ID returned from the registry to confirm its validity and confidence score before proceeding.
- 3check-pre-x402-guardRun spend-cap, identity, and URL safety checks against the target endpoint to get a final allow/deny decision before committing to payment.
Post-Transaction Refund Assessment
Use when an agent needs to determine refund eligibility after a paid x402 call returned a poor or empty response, by first checking the seller endpoint and then arbitrating eligibility.
- 1check-pre-x402-guardRetrieve endpoint reachability and identity trust signals for the seller URL, which feed into the verification score inputs required by the refund arbiter.
- 2evaluate-refund-eligibilitySubmit the verification score, endpoint reachability, and response quality signals to receive a graded refund eligibility decision and buyer guidance.

Own x402-agent-suite-production.up.railway.app? List it with your agent
Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 4 of 31 routes have never been scored — the audition tests them for the first time.
- 4 routes are in the 50–74 band — working, but with room to climb.
- 2 routes are flagged by the verifier as failing or inconclusive.
Paste this to your agent
Make my x402 API at https://x402-agent-suite-production.up.railway.app discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://x402-agent-suite-production.up.railway.app --json`. Heads up: 4 routes have never been scored — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
