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 lupapago-fee-changelog-b845102f ``` Example prompt: Can you pull the LupaPago fee changelog for all Argentine PSPs since 2026-09-01 and tell me which ones had actual rate changes versus just a verified_at refresh? ## When to prefer this Choose this endpoint when you need a dated, curated audit trail of Argentine PSP fee changes — especially to detect whether a rate changed versus just a verification refresh — rather than fetching current live fee rates. Prefer it over a fee-compare endpoint when the goal is historical tracking, compliance monitoring, or answering 'when did this last change?' questions for specific PSPs. ## Known failure modes - Invalid date format for 'since' param (must match YYYY-MM-DD pattern) returns a validation error - Unknown or misspelled PSP slug returns an empty entries array with count 0 - Payment not completed (x402 flow failure) returns HTTP 402 before data is delivered - Network timeout if upstream audit data is temporarily unavailable - HEAD or DELETE method returns empty body with metadata headers only ## How this service works Compará pasarelas de pago en Argentina: fees, liquidación e integraciones. Directorio independiente ecommerce-first. ## Output Returns a JSON object with a count of matching entries, the since date used, and an array of changelog entries. Each entry includes the PSP slug, audit date, a human-readable summary of what was verified or changed (including rate details), and a source URL pointing to the official PSP pricing page that was audited. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string" }, "headers": { "type": "object", "additionalProperties": { "type": "string" } }, "queryParams": { "type": "object", "properties": { "psp": { "type": "string", "description": "Optional PSP slug filter (fee-pack or changelog slug)" }, "since": { "type": "string", "pattern": "^\\d{4}-\\d{2}-\\d{2}$", "description": "ISO date YYYY-MM-DD — include entries on/after" } }, "additionalProperties": false } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object" } } } } } ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "count": 9, "since": "2026-09-01", "entries": [ { "psp": "mercado-pago", "date": "2026-09-18", "summary": "Auditoría P0 2026-09-18: MATCH vs QR / Point Smart / Point Tap / Checkout oficiales.
