## 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 machina-sports-entity-resolver-a4041406 -d '<json body>'
```

Example prompt: Can you resolve the Sportradar ID 'sr:competitor:36' through Machina Sports so I can see what team that is and get all its cross-provider IDs including api_football, Opta, and ESPN?

## When to prefer this

Use this endpoint when you need to translate a sports entity ID from one data provider into a unified canonical representation and/or retrieve equivalent IDs from other providers — especially when working with World Cup data across multiple feeds (e.g. reconciling Sportradar fixtures with Opta player data or Entain odds). Prefer this over manual mapping tables or provider-specific lookup endpoints when cross-provider consistency is required.

## Known failure modes

- Unknown or invalid provider ID returns a not-found error
- Malformed or empty ID string returns a validation error
- Provider prefix not recognised (must be one of api_football, sportradar, opta, entain, espn, or machina URN) returns a bad-request error
- Payment failure (x402) if USDC balance insufficient
- Rate limiting or timeout for high-frequency resolution calls

## How this service works

Resolves a provider id (api_football, sportradar, opta, entain, espn) or canonical machina URN to the entity it identifies, with all cross-provider ids attached.

## Output

Returns the canonical Machina entity corresponding to the supplied provider ID or URN, including the entity's type (team, player, fixture, etc.), canonical Machina URN, and a full set of cross-provider IDs covering api_football, Sportradar, Opta, Entain, and ESPN where available.
