Omit it — or send the empty string — to start at the newest entry. It names a position in the newest-first order rather than an offset, so a page you have already read never shifts under you: an entry that arrives mid-walk takes the place its own publish date gives it — above the cursor, on ground you have already covered, or below it, still ahead of you — instead of renumbering every page behind it. It does not expire; a walk can be paused and resumed. Do not construct or edit one: a token that is malformed, or was issued for a different vendor, is refused with 400 and is never charged."}}}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"enum":["json"],"type":"string"},"example":{"type":"object"}},"description":"Full structured recent releases (paid)"}},"description":"Call shape for GET /api/monitors/{slug}."},"responseSchema":null,"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.01","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"probe","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.01/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.01","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.01","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_TJGCjF6y78eroOqO8JCJH","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.01","costPer":"request","priority":0,"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Returns structured, paginated recent release entries for the Anthropic vendor as tracked by the Changelog State monitor.","exampleAgentPrompt":"Pull the 10 most recent structured release entries for Anthropic from the Changelog State tracker so I can see what they've shipped lately.","exampleUseCases":[{"title":"Track Anthropic model release history","prompt":"Can you fetch the latest 10 Anthropic releases from the Changelog State monitor and summarize what new models or API changes they've announced?"},{"title":"Alert on new Anthropic releases","prompt":"Check the Changelog State API for Anthropic and tell me if there are any releases I haven't seen yet — grab the most recent 5 entries."},{"title":"Compare Anthropic release cadence","prompt":"Pull up to 50 recent Anthropic release entries from the Changelog State tracker so I can analyze how frequently they've been shipping updates."}],"resultDescription":"A JSON object containing a list of structured release entries for Anthropic, each with metadata such as version identifiers, release dates, and descriptions, limited by the requested count (default 10, max 50).","failureModes":["Invalid or unrecognized vendor slug returns an error or empty result","limit parameter out of range (below 1 or above 50) causes a validation error","Payment not processed correctly results in 402 response blocking data access","Service unavailability on Replit infrastructure may cause timeouts or 5xx errors","No releases tracked yet for the vendor may return an empty list"],"whenToPreferThis":"Choose this endpoint when you need structured, machine-readable recent release data specifically for Anthropic and want a pre-monitored, paid feed rather than scraping changelog pages yourself.
