# Alternatives for API access

Reaching these models from code: going direct to providers versus using an aggregator API, and what each costs you in work.

## What changes when you need code

Consumer platforms are built for a browser. Once generation has to run inside your own product or pipeline, the requirements change: authentication, predictable errors, idempotency so a retry cannot double-charge, and a way to poll long-running jobs.

## Direct versus aggregated

|  | Direct provider APIs | Aggregator API |  |

| Cost per generation | Lowest | Includes a platform margin |  |

| New features | First | After integration |  |

| Integration work | One per provider | One, total |  |

| Billing | Separate per provider | One balance |  |

| Error handling | Different shapes per provider | Normalised |  |

The tipping point is roughly the same as for the consumer question: one model means go direct; three or more and the integration work you avoid is worth the margin.

## What to check in any generation API

  - **Submit-and-poll, not a blocking call.** Renders take minutes; an API that holds the connection will time out.
  - **Idempotency keys**, so a dropped connection and retry cannot charge twice.
  - **Structured errors** with stable machine-readable codes, not HTML error pages.
  - **Rate-limit headers** you can self-throttle against, and `Retry-After` on a 429.
  - **A cost estimate endpoint**, so you can quote before committing.
  - **A sandbox** to rehearse the request shape without spending.

An API missing the first three will cost you more in engineering than it saves in credits, regardless of the per-generation price.

## Common questions

### Does Higgsfield have a public API?

Check their developer documentation for current availability — API surfaces change and are not always public. This page covers how to evaluate any option.

### Is an aggregator API worth the margin?

If you need three or more models, usually yes — you pay a margin instead of building and maintaining several integrations.
