How this service works
Library entries and articles whose verified_at is on or after since (YYYY-MM-DD). One request is 0.01 USDC. An unpaid challenge returns a count and the first three ids and titles. The files on https://agentpaywire.com stay free.
Output
A JSON object containing: the since date used for filtering, a comparison operator string (e.g. 'verified_at >= since'), a count of matching entries, and an array of entries — each with an id, url, kind (e.g. library, article), title, verified_at date, and date_published date.
Example use cases
Monitor new agent payment resources
“What has Agent Paywire verified about AI agent payment protocols since March 1, 2026? I want to stay on top of any new libraries or articles that have been curated.”
Research stablecoin payment infrastructure
“Show me all the entries on the Agent Paywire updates feed verified after October 1, 2025 — I'm researching how AI agents handle stablecoin and machine-to-machine payments.”
Track x402 and L402 developments
“Get me the latest verified entries from Agent Paywire since July 1, 2026 so I can see what new tools or writing has appeared about x402 and L402 for agents.”
Technical details
Endpoint
GEThttps://api.agentpaywire.com/v1/updates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a curated, machine-verified feed of resources specifically about AI agent payment protocols (stablecoins, x402, L402, machine-to-machine payments). It is ideal for monitoring new additions to the Agent Paywire knowledge base over time using a since-date filter. Prefer this over general web search when you want structured, verified metadata (kind, verified_at, url) rather than raw search results.
Side effects
- Missing 'since' query parameter returns an error — the parameter is required
- Invalid or unparseable date format for 'since' may return a 400 error
- Payment not completed (x402 flow not fulfilled) results in a 402 Payment Required response
- No entries matching the since filter returns an empty entries array with count 0
- Upstream service unavailability may return a 5xx error
