How this service works
3-node swarm that scores x402 Payment Required calls and returns a GO/NO-GO credit recommendation.
Output
Returns a JSON object containing a status string, a final_creditability_score integer (e.g. 820), a final_recommendation of GO or NO-GO, an optional trust_level label, an array of node_reports from each of the 3 swarm nodes, and an array of aggregated_flags describing any detected risk signals.
Example use cases
Pre-payment trust check for agent
“My AI agent is about to pay an x402-protected endpoint at https://inference.vendor.io/generate — can you run it through the crediting swarm and tell me if the creditability score is high enough to trust?”
Vet unknown x402 vendor before integration
“I found this x402 API at https://unknown-data-api.up.railway.app/feed and the payTo address is 0xABC123. Can you score it with the crediting swarm and flag any risks before I wire it up?”
Automated payment gate in agentic workflow
“Before approving any x402 payment in my pipeline, I want to score the target endpoint with the crediting swarm and only proceed if the final recommendation is GO — can you check https://premium-signals.io/api/v1?”
Technical details
Endpoint
POSThttps://x402-crediting-swarm-production.up.railway.app/api/swarmWhen to prefer
Choose this endpoint when an AI agent or automated workflow needs to evaluate whether an x402 Payment Required endpoint is trustworthy before committing a micropayment. It is especially useful in agentic pipelines where the agent must autonomously decide whether to pay unknown or third-party x402 APIs. Prefer this over manual inspection when you need a structured, scored, multi-node consensus recommendation rather than a simple URL check.
Side effects
- Missing required endpoint_url field returns a validation error
- Unreachable or non-existent endpoint_url may result in low score or error status
- Invalid method enum value (not POST/PUT/PATCH) causes schema rejection
- Malformed payload body causes parsing failure
- Transient upstream swarm node failures may return partial or degraded results
