# 2s Document Store — Put (Index Document)

> 2s Document Store — Put (Index Document) is a paid API for AI agents from 2s.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Store and full-text index a text document within a named namespace, with optional metadata and secret redaction, for later retrieval via search.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 2s-document-store-put-index-document-f4c91cbc -d '<json body>'
```

Example prompt: Index this article under namespace 'research-notes' with id 'climate-2024-01': 'Global temperatures in 2024 continued to break records across all continents...' — tag it with metadata {"title":"Climate 2024","tags":["climate","research"]} and strip any secrets before storing.

## When to prefer this

Use this endpoint when you need to persist and make searchable a text document within a named namespace, especially within the 2s.io ecosystem where sibling search endpoints can later retrieve it. Prefer this over generic object storage when full-text search retrieval is required. Particularly useful for agent memory, knowledge base construction, or document indexing workflows where pay-per-call economics are preferred over subscription storage services.

## Known failure modes

- Body exceeds 1 MB limit — request rejected
- Document id exceeds 256 characters — validation error
- Missing required body field — 400 error
- Namespace not specified — document may be placed in default or rejected
- Payment failure via x402 — call not executed

## 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

A confirmation that the document has been stored and indexed in the specified namespace under the given id, ready to be retrieved via subsequent search queries.
