RSS Feed Aggregator
Fetch a public RSS or Atom feed with private-network blocking and return bounded current entries.
Preview request
The preview path is rate-limited and does not charge. It executes the live source and returns the paid response shape while withholding decision-ready values. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.
curl --request GET \ "https://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/rss_aggregator?preview=true&feed_url=https%3A%2F%2Fnews.ycombinator.com%2Frss&limit=3"
Input contract
| Parameter | Type | Required | Description |
|---|---|---|---|
feed_url | string | Yes | URL of the RSS/Atom feed. |
limit | integer | No | Number of latest items to retrieve. |
Example deliverable
This is the documented response shape, not a promise that live values will match the example. The paid request returns current or declared-source results using the same contract.

}Purchase decision
Buy when: the active task needs this product's structured result, its declared source and freshness are sufficient, and 0.02 USDC is within the buyer's authorized per-request limit.
Skip when: a cached result is sufficient, the source or fields do not satisfy the task, or the buyer has not authorized payment. Do not bypass wallet, budget, or user-approval policy.
Guaranteed response metadata
Every successful product response identifies how the result was produced. Product-specific output fields are documented in the paid OpenAPI contract. The preview proves the live source and field types without returning the paid values.

Fast path: install the public MCP package, configure a dedicated low-balance Base buyer wallet and a maximum per-request spend, then call this tool with auto_pay: true. The client handles the challenge, local signature, settlement, and retry in one tool call.
