How this service works
Índice de liquidación LatAm: qué endpoint puede pagar un agente ahora (mainnet, 402 live) y llevarse los datos. No es LupaRiel (rieles) ni LupaPago (fees).
Output
A JSON object containing a ranked list of Plaza listings, each with title, pay_url, price in USD, rail, chain, and plaza_id. Also includes metadata: total count, applied filters (rail, chain, max_price), product name, ruleset version, and a disclaimer. Capped at 20 results per call.
Example use cases
Budget API discovery for agent
“Find me all LupaPlaza Plaza listings on the Base chain that cost 2 cents or less per call — I want to see their names and where to pay.”
Checking available data APIs
“Search LupaPlaza for any x402 endpoints I can call right now on Base, with a max price of 5 cents — give me the full list with prices.”
Scouting cheap LatAm data feeds
“Look up what LupaPlaza has in its catalog under $0.01 on the Base chain — I'm specifically looking for data feeds I can afford to call frequently.”
Technical details
Endpoint
GEThttps://lupaplaza.com/api/discover?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover which x402-payable APIs are currently live and affordable on the Base chain. It is the right choice when building agent workflows that need to self-select tools at runtime based on price constraints, or when exploring the LupaPlaza Plaza catalog programmatically. Prefer this over static API directories when you need real-time listings with payment metadata.
Side effects
- Invalid or unsupported rail value (only 'x402' accepted) returns an error
- Invalid or unsupported chain value (only 'base' / eip155:8453 accepted) returns an error
- max_price value that cannot be parsed as a number returns a validation error
- No listings match the filter criteria — returns empty results array with count 0
- Payment not provided or rejected — 402 response requiring USDC payment before results are returned
- Network or service downtime returns a 5xx error
