How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
A JSON object including the EIP-155 network identifier (eip155:8453 for Base), the product name ('feed-snapshot'), an assessment object with a risk_level (e.g. 'low'), a numeric risk_score, and an array of any flags detected in the feed.
Example use cases
Example prompt
“Can you run a safety preflight check on this RSS feed — https://feeds.example.com/posts.xml — and tell me its risk score and any flags before I start ingesting it?”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/web/feed-snapshotWhen to prefer
Use this endpoint when an autonomous agent needs to preflight-check a public RSS or Atom feed URL for safety and risk before ingesting or subscribing to it, especially in Base/EVM-adjacent workflows where agent safety tooling is required. Prefer over generic HTTP fetch tools when you need structured risk scoring and flag detection specific to feed content.
Side effects
- Invalid or non-public URL returns validation error
- Non-RSS/Atom URL (e.g. plain HTML page) may return parse failure or unexpected assessment
- Timeout if the remote feed server is slow or unreachable
- Malformed feed XML may result in partial or error response
- Missing required 'url' query parameter returns schema validation error
