How this service works
Machina's World Cup Intelligence APIs cover the 2026 tournament: canonical entity resolution across providers, fixtures, standings, squads, injuries, per-player performance context, Dixon-Coles match forecasts with historical backtests, and finished editorial content. Every endpoint is a synchronous POST that returns grounded, source-cited JSON. This server is a pay-per-use, transparent proxy in front of Machina Sports's own API: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its live price in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.
Output
Returns a status field (e.g. 'quoted', 'ready', 'needs_input'), a priceUsd always set to '0' confirming no charge for this lookup, a Markdown guide with task result, exact API contract, pricing, and next steps, and a guideUrl pointing to the wallet-free advisor endpoint for further planning or recovery.
Example use cases
Budget planning for fixture data
“I need fixture results and standings for the 2026 World Cup — roughly 200 API calls. Can you get me a quote showing the price and what I need to set up before I can start calling those endpoints?”
Choosing the right endpoint for player stats
“I want per-player performance context for World Cup 2026 matches — what's the exact API contract I should use, what will it cost per call, and what are the prerequisites? I'm planning about 1000 calls with a $50 budget.”
Comparing payment options for autonomous agent
“My agent will be running autonomously without a human in the loop — can you find me a guide on which Machina sports APIs cover match forecasts, what payment methods work (x402 or card), and how to get started with no wallet?”
Technical details
Endpoint
POSThttps://agents.machina.gg/zeroclick/agent/quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to plan, budget, or explore Machina's World Cup 2026 API surface before committing to a purchase. It is the right first step when you don't yet know which endpoint to call, what it costs, or what prerequisites are required. It is especially useful for autonomous agents that need to verify feasibility and price before authorizing spend, or for users without a wallet who need guidance. Prefer this over directly calling a paid endpoint when the task requirements, cost, or API contract are uncertain.
Side effects
- goal field missing or empty — returns validation error
- goal description too vague to match a specific API — status returns 'needs_input' or 'unknown'
- requested capability not available in Machina catalog — status returns 'unsupported' or 'unavailable'
- budgetUsd format invalid (non-numeric or wrong pattern) — schema validation failure
- quantity out of range (0 or over 1,000,000) — schema validation failure
Input
Schema · Request body
| Field | Type | Description |

| quantity | integer | Number of API calls, not returned items. Omit when unknown; describe desired output in goal. |
| budgetUsd | string | Total cash budget in USD. A quote does not authorize spending. |
| requirements | string | |
| humanAvailable | boolean | Whether a human is in the loop. False recommends anonymous auth for a new autonomous identity; omit when unknown. Executing a human's request without further interruptions does not by itself mean false. |
| budgetExclusive | boolean | |
