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 ranked list of matching documents (up to the specified limit, default 50, max 1000) from the specified namespace that satisfy the FTS5 query, including document content and relevance metadata.
Example use cases
Retrieve invoices by keyword
“Search the 'invoices' namespace for any document containing 'overdue AND 2024' and show me the top 50 hits.”
Find agent memory by phrase
“Look through my 'agent-logs' namespace for documents that mention the exact phrase "task completed" — give me up to 200 results.”
Wildcard search across stored notes
“Search the 'research-notes' namespace for everything matching 'climat*' so I can find all my climate-related notes, limit to 75 results.”
Technical details
Endpoint
POSThttps://2s.io/api/store/doc-searchWhen to prefer
Use this endpoint when you have already stored documents in a 2s namespace and need to retrieve them by content using full-text search with FTS5 syntax (boolean operators, exact phrases, prefix wildcards). Prefer this over generic web search when querying private, agent-owned document stores. It is the right choice for agent memory retrieval, stored knowledge bases, or any corpus you previously uploaded to 2s storage.
Side effects
- Empty namespace or namespace not found returns zero hits
- Malformed FTS5 query syntax returns a parse error
- Limit out of range (below 1 or above 1000) returns a validation error
- Missing required 'query' field returns a 400-style error
- No matching documents returns an empty result set
