Any RSS or Atom feed

# Any RSS or Atom feed

The items of any RSS 2.0 or Atom feed: title, link, publication time, author, the first 300 characters of the summary, and the item's id. Give the feed's `url`; `limit` caps the rows (up to 200). Columns: title, link, published, author, summary, id.
Upstream direct: USD 0.00015/successful call.
Overflow: not published (unknown; not zero).
Disabled draft retail: maximum of published direct/overflow fixed prices, without markup. Unknown overflow is not a zero quote. Draft retail USD 0.00015/billable call.
Usage limits: Public RSS/Atom only. This configuration caps limit at 1-25; this is a platform restriction, not a published upstream maximum. Empty rows incur no retail charge. Preserve authors and original links. No paywalled full text is provided, and access to every feed is not guaranteed.
Supplier limits: Prepaid credits, 1 credit = $0.001 at the $10 pack. A page already in Crawl4AI's archive costs half; the effort a page needed sets the rest (x0.5 archived, x1 light/standard, x2 browser, x4 the site fought back). Every priced answer carries its exact charge in x-c4-cost (credits) and the running balance in x-c4-balance; a batch line carries "cost" and the stream ends with a {"summary": {"cost": …}} line; a finished job reports usage.cost. Blocked (403), unreachable (502) and fleet-busy (503) answers are not charged. Out of credit answers 402 no_credit, the account's own monthly cap 402 spend_cap, the plan's monthly allowance 402 plan_cap; per-plan pace limits answer 429 with X-RateLimit-* headers. GET /v1/billing/balance trails the per-call header by about a minute.
Catalog prices and provider response fields are not proof of actual TREG charges. Reconcile X-Treg-Cost-Micro with call IDs and usage records; caching and overflow may change the charge.
Before enabling, verify business results and charges for this account, plus X-Treg-Meta customer tagging and usage-by-tag reconciliation. Testnet verification results for this definition are recorded below.
Testnet verification (2026-11-04): business result passed; OpenAny debit USD 0.00015 matched the configured retail policy for this request. This is one observed call, not a guarantee for future requests. The paired example is captured from testnet; long excerpts may be shortened. Actual TREG upstream debit was not verified.
