How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
Returns a JSON object with an array of blob metadata items (key, size in bytes, content type, expiration timestamp), a pagination cursor for fetching the next page, and an optional total count. Source provenance (provider, URL, license) is also included.
Example use cases
Audit agent-cached data keys
“Show me all the keys stored in my 'reports' namespace — I want to see what my agent has cached, including their sizes and when they expire.”
Paginate through large blob namespace
“I have a lot of blobs in my 'pipeline-outputs' namespace. Get me the first 200 keys, then I'll page through the rest using the cursor you return.”
Find blobs by key prefix
“List all blobs in my 'user-data' namespace that start with the prefix 'user:42/' so I can see everything stored for that user.”
Technical details
Endpoint
POSThttps://2s.io/api/store/blob-listWhen to prefer
Use this endpoint when you need to enumerate, browse, or audit keys stored in a 2s.io blob namespace — especially when filtering by prefix or paginating through large collections. Prefer this over a direct blob fetch when you don't know which keys exist yet or need to discover what's been stored.
Side effects
- Invalid or unknown namespace returns empty items array
- Malformed cursor causes pagination error or unexpected results
- Limit out of range (below 1 or above 1000) triggers validation error
- Namespace not found may return ok:true with empty items rather than an error
- Payment failure (x402) blocks request before reaching storage layer
