Shipping api content negotiation accept without regret means you keep api content correct under retries and partial failure — with a named owner, a measurable signal, and a rollback a tired on-call can run. I reach for this when enterprise buyers ask how you prove it works; that is also when shortcuts like retries without idempotency keys start paging people.

This write-up is specific to api-content-negotiation-accept in a product context, using Postgres, Prometheus, OpenTelemetry for the mechanics while keeping ownership human.

Concretely, being able to keep api content correct under retries and partial failure forces explicit choices: source of truth, timeout budgets, and which errors users see versus operators.

// Shipping api content negotiation accept without regret
export async function handle_api_content_negotiation_accept(input: unknown): Promise<Result> {
  const parsed = schema.safeParse(input);
  if (!parsed.success) throw new ValidationError(parsed.error);
  const span = tracer.startSpan("api-content-negotiation-accept");
  try {
    if (await repo.seen(parsed.data.idempotencyKey)) return { ok: true, deduped: true };
    const out = await repo.execute(parsed.data);
    await repo.mark(parsed.data.idempotencyKey);
    return out;
  } finally {
    span.end();
  }
}
