How this service works
Running a Paid x402 Endpoint on 2026-08-08: The Failure Modes, Measured Against the Live Registry and Catalog. Almost everything written about x402 is written for the buyer: how an agent pays, which wallet to give it, how not to get it drained. This is the other side. You have a paid HTTP endpoint, agents are supposed to discover it and buy from it, and the question is what actually breaks. As of 2026-08-08. Every SDK claim below names a version, every spec claim names a document, and the two datasets are first-party: a census of the ERC-8004 Identity Registry on Base taken at block 49,706,971, and a com

Choose this endpoint when you specifically need the full text of this x402 failure-modes analysis article from Tenjin's agent-rails creator. It is the authoritative pay-per-read source for first-party x402 endpoint operator data including the ERC-8004 census and live catalog measurements.

Side effects
- Payment challenge not completed — returns 402 if the x402 payment is not submitted or is invalid
- Invalid handle or slug — returns 404 if the creator handle or article slug does not exist
- Slug 'latest' used with a handle instead of wallet address — not payable, returns error
- Unclaimed creator accessed by handle instead of wallet address — only address form works for unclaimed creators
- Network or chain RPC errors causing payment verification failure
