# Use the Agent Paywire library

The library is public. Reading it does not require payment.

## Files

- Full document: https://agentpaywire.com/api/library.json
- One category: https://agentpaywire.com/api/library/{category}.json
- Tag list: https://agentpaywire.com/api/library/tags.json
- One tag: https://agentpaywire.com/api/library/tag/{tag}.json
- Compact index: https://agentpaywire.com/api/search-index.json
- Dates: https://agentpaywire.com/api/updated-since/index.json
- One date: https://agentpaywire.com/api/updated-since/{date}.json
- Protocol facts: https://agentpaywire.com/api/protocol-facts.json

Bitcoin and Lightning is the featured category and is listed first.

## Filter

The search index documents the filter a later API or MCP worker applies:

- `q`: case-insensitive substring of id, title, summary, or publisher
- `category`: exact category id
- `tag`: exact tag
- `type`: exact library type
- `featured`: true keeps featured records
- `updated_since`: YYYY-MM-DD. Keep records whose verified_at is greater than this date

A day file lists records verified on that date. To sync, read every day file after your cursor. The same records are in https://agentpaywire.com/changelog.json.

## Limits

Summaries are ours. Linked pages belong to their publishers. This skill does not give investment advice.
